    <summary>Represents the simple binding between the property value of an object and the property value of a control.</summary>
    <remarks>
      <format type="text/markdown"><![CDATA[

## Remarks
 Use the <xref:System.Windows.Forms.Binding> class to create and maintain a simple binding between the property of a control and either the property of an object, or the property of the current object in a list of objects.

 As an example of the first case, you can bind the <xref:System.Windows.Forms.Control.Text> property of a <xref:System.Windows.Forms.TextBox> control to the `FirstName` property of a `Customer` object. As an example of the second case, you can bind the <xref:System.Windows.Forms.Control.Text> property of a <xref:System.Windows.Forms.TextBox> control to the `FirstName` property of a <xref:System.Data.DataTable> that contains customers.

 The <xref:System.Windows.Forms.Binding> class also enables you to format values for display through the <xref:System.Windows.Forms.Binding.Format> event and to retrieve formatted values through the <xref:System.Windows.Forms.Binding.Parse> event.

 When constructing a <xref:System.Windows.Forms.Binding> instance with <xref:System.Windows.Forms.Binding.%23ctor*> constructor, you must specify three items:

- The name of the control property to bind to.

- The data source.

- The navigation path that resolves to a list or property in the data source. The navigation path is also used to create the object's <xref:System.Windows.Forms.Binding.BindingMemberInfo> property.

 First, you must specify name of the control property you want to bind the data to. For example, to display data in a <xref:System.Windows.Forms.TextBox> control, specify the <xref:System.Windows.Forms.TextBoxBase.Text> property.

 Second, you can specify an instance of any one of the classes in the following table as the data source.

|Description|C# example|
|-----------------|-----------------|
|Any class that implements <xref:System.ComponentModel.IBindingList> or <xref:System.ComponentModel.ITypedList>. These include the following: <xref:System.Data.DataSet>, <xref:System.Data.DataTable>, <xref:System.Data.DataView>, or <xref:System.Data.DataViewManager>.|`DataSet ds = new DataSet("myDataSet");`|
|Any class that implements <xref:System.Collections.IList> to create an indexed collection of objects. The collection must be created and filled before creating the <xref:System.Windows.Forms.Binding>. The objects in the list must all be of the same type; otherwise, an exception will be thrown.|`ArrayList ar1 = new ArrayList;  Customer1 cust1 = new Customer("Louis");  ar1.Add(cust1);`|
|A strongly typed <xref:System.Collections.IList> of strongly typed objects|`Customer [] custList = new Customer[3];`|

 Third, you must specify the navigation path, which can be an empty string (""), a single property name, or a period-delimited hierarchy of names. If you set the navigation path to an empty string, the <xref:System.Object.ToString*> method will be called on the underlying data source object.

 If the data source is a <xref:System.Data.DataTable>, which can contain multiple <xref:System.Data.DataColumn> objects, the navigation path must be used to resolve to a specific column.

> [!NOTE]
> When the data source is a <xref:System.Data.DataSet>, <xref:System.Data.DataViewManager>, or <xref:System.Data.DataTable>, you are actually binding to a <xref:System.Data.DataView>. Consequently, the bound rows are actually <xref:System.Data.DataRowView> objects.

 A period-delimited navigation path is required when the data source is set to an object that contains multiple <xref:System.Data.DataTable> objects (such as a <xref:System.Data.DataSet> or <xref:System.Data.DataViewManager>). You can also use a period-delimited navigation path when you bind to an object whose properties return references to other objects (such as a class with properties that return other class objects). For example, the following navigation paths all describe valid data fields:

-   "Size.Height"

-   "Suppliers.CompanyName"

-   "Regions.regionsToCustomers.CustomerFirstName"

-   "Regions.regionsToCustomers.customersToOrders.ordersToDetails.Quantity"

 Each member of the path can return either a property that resolves to a single value (such as an integer), or a list of values (such as an array of strings). Although each member in the path can be a list or property, the final member must resolve to a property. Each member builds on the previous member: "Size.Height" resolves to the <xref:System.Drawing.Size.Height> property for the current <xref:System.Drawing.Size>; "Regions.regionsToCustomers.CustomerFirstName" resolves to the first name for the current customer, where the customer is one of the customers for the current region.

 A <xref:System.Data.DataRelation> returns a list of values by linking one <xref:System.Data.DataTable> to a second <xref:System.Data.DataTable> in a <xref:System.Data.DataSet>. If the <xref:System.Data.DataSet> contains <xref:System.Data.DataRelation> objects, you can specify the data member as a <xref:System.Data.DataTable.TableName*> followed by a <xref:System.Data.DataRelation.RelationName*>, and then a <xref:System.Data.DataColumn.ColumnName*>. For example, if the <xref:System.Data.DataTable> named "Suppliers" contains a <xref:System.Data.DataRelation> named "suppliers2products", the data member could be "Suppliers.suppliers2products.ProductName".

 The data source can consist of a set of related classes. For example, imagine a set of classes that catalogs solar systems. The class named `System` contains a property named `Stars` that returns a collection of `Star` objects. Each `Star` object has `Name` and `Mass` properties, as well as a `Planets` property that returns a collection of `Planet` objects. In this system, each planet also has `Mass` and `Name` properties. Each `Planet` object further has a `Moons` property that returns a collection of `Moon` objects, each of which also has `Name` and `Mass` properties. If you specify a `System` object as the data source, you can specify any of the following as the data member:

-   "Stars.Name"

-   "Stars.Mass"

-   "Stars.Planets.Name"

-   "Stars.Planets.Mass"

-   "Stars.Planets.Moons.Name"

-   "Stars.Planets.Moons.Mass"

 Controls that can be simple-bound feature a collection of <xref:System.Windows.Forms.Binding> objects in a <xref:System.Windows.Forms.ControlBindingsCollection>, which you can access through the control's <xref:System.Windows.Forms.Control.DataBindings> property. You add a <xref:System.Windows.Forms.Binding> to the collection by calling the <xref:System.Windows.Forms.ControlBindingsCollection.Add*> method, thereby binding a property of the control to a property of an object (or to a property of the current object in a list).

 You can simple-bind to any object that derives from the <xref:System.Windows.Forms.Control?displayProperty=nameWithType> class, for example, the following Windows controls:

-   <xref:System.Windows.Forms.Button>

-   <xref:System.Windows.Forms.CheckBox>

-   <xref:System.Windows.Forms.CheckedListBox>

-   <xref:System.Windows.Forms.ComboBox>

-   <xref:System.Windows.Forms.DateTimePicker>

-   <xref:System.Windows.Forms.DomainUpDown>

-   <xref:System.Windows.Forms.GroupBox>

-   <xref:System.Windows.Forms.HScrollBar>

-   <xref:System.Windows.Forms.Label>

-   <xref:System.Windows.Forms.LinkLabel>

-   <xref:System.Windows.Forms.ListBox>

-   <xref:System.Windows.Forms.ListView>

-   <xref:System.Windows.Forms.MonthCalendar>

-   <xref:System.Windows.Forms.NumericUpDown>

-   <xref:System.Windows.Forms.PictureBox>

-   <xref:System.Windows.Forms.ProgressBar>

-   <xref:System.Windows.Forms.RadioButton>

-   <xref:System.Windows.Forms.RichTextBox>

-   <xref:System.Windows.Forms.ScrollBar>

-   <xref:System.Windows.Forms.StatusBar>

-   <xref:System.Windows.Forms.TextBox>

-   <xref:System.Windows.Forms.TreeView>

-   <xref:System.Windows.Forms.VScrollBar>

> [!NOTE]
> Only the <xref:System.Windows.Forms.ListControl.SelectedValue> property of the <xref:System.Windows.Forms.ComboBox>, <xref:System.Windows.Forms.CheckedListBox>, and <xref:System.Windows.Forms.ListBox> control is simple bound.

 The <xref:System.Windows.Forms.BindingManagerBase> class is an abstract class that manages all the <xref:System.Windows.Forms.Binding> objects for a particular data source and data member. Classes that derive from <xref:System.Windows.Forms.BindingManagerBase> are the <xref:System.Windows.Forms.CurrencyManager> and the <xref:System.Windows.Forms.PropertyManager> classes. How a <xref:System.Windows.Forms.Binding> is managed depends on whether the <xref:System.Windows.Forms.Binding> is a list binding or a property binding. For example, if it is a list binding, you can use the <xref:System.Windows.Forms.BindingManagerBase> to specify a <xref:System.Windows.Forms.BindingManagerBase.Position*> in the list; the <xref:System.Windows.Forms.BindingManagerBase.Position*>, therefore, determines which item (out of all items in the list) is actually bound to a control. To return the appropriate <xref:System.Windows.Forms.BindingManagerBase>, use the <xref:System.Windows.Forms.BindingContext>.

 To add a new row to a set of controls bound to the same <xref:System.Windows.Forms.Binding.DataSource*>, use the <xref:System.Windows.Forms.BindingManagerBase.AddNew*> method of the <xref:System.Windows.Forms.BindingManagerBase> class. Use the <xref:System.Windows.Forms.BindingContext.Item*> property of the <xref:System.Windows.Forms.BindingContext> class to return the appropriate <xref:System.Windows.Forms.CurrencyManager>. To escape the addition of the new row, use the <xref:System.Windows.Forms.CurrencyManager.CancelCurrentEdit*> method.



## Examples
 The following code example creates a Windows Form with several controls that demonstrate simple data binding. The example creates a <xref:System.Data.DataSet> with two tables named `Customers` and `Orders`, and a <xref:System.Data.DataRelation> named `custToOrders`. Four controls (a <xref:System.Windows.Forms.DateTimePicker> and three <xref:System.Windows.Forms.TextBox> controls) are data bound to columns in the tables. For each control, the example creates and adds a <xref:System.Windows.Forms.Binding> to the control through the <xref:System.Windows.Forms.Control.DataBindings> property. The example returns a <xref:System.Windows.Forms.BindingManagerBase> for each table through the form's <xref:System.Windows.Forms.BindingContext>. Four <xref:System.Windows.Forms.Button> controls increment or decrement the <xref:System.Windows.Forms.BindingManagerBase.Position> property on the <xref:System.Windows.Forms.BindingManagerBase> objects.

          <format type="text/markdown"><![CDATA[

## Remarks
 You can specify an instance of any of the following classes for the data source:

-   <xref:System.Data.DataSet>

-   <xref:System.Data.DataTable>

-   <xref:System.Data.DataView>

-   <xref:System.Data.DataViewManager>

-   <xref:System.Windows.Forms.BindingSource>

- Any class that implements the <xref:System.Collections.IList> interface

- Any class

 See the <xref:System.Windows.Forms.Binding> class for more information about creating the `dataMember` string.

 When you create a binding to a control's property, the new <xref:System.Windows.Forms.Binding> inspects the events exposed by the bound control and attaches to two particular events:

-   <xref:System.Windows.Forms.Control.Validating?displayProperty=nameWithType>

- An event named *PropertyName*`Changed` (for example, <xref:System.Windows.Forms.Control.BackColorChanged?displayProperty=nameWithType>)

 If you attempt to bind to a property that does not exist, an <xref:System.ArgumentException> will be thrown when the <xref:System.Windows.Forms.Binding> is added to the control's <xref:System.Windows.Forms.Control.DataBindings*?displayProperty=nameWithType> collection.



## Examples
 The following code example binds a <xref:System.Windows.Forms.TextBox> control to a table column in a <xref:System.Data.DataSet> named `myDataSet`. The example requires that you have declared `myDataSet` in the declarations section of the module.

        <summary>Occurs when the <see cref="P:System.Windows.Forms.Binding.FormattingEnabled" /> property is set to <see langword="true" /> and a binding operation is complete, such as when data is pushed from the control to the data source or vice versa.</summary>

## Remarks
 This event is raised under any of the following conditions when <xref:System.Windows.Forms.Binding.FormattingEnabled*> is `true`:

- Data from the data source is pushed onto the control property.

- Data from the control property is pushed onto the data source.

 This event is raised at the completion of these operations, independent of the completion status. For example, if a binding operation binds a null value to a <xref:System.Windows.Forms.DateTimePicker.Value> property, an exception is thrown, but the <xref:System.Windows.Forms.Binding.BindingComplete> event still occurs. The handler of this event can take the appropriate action, based on the success, error, or exceptions in the binding process, by examining the <xref:System.Windows.Forms.BindingCompleteEventArgs.BindingCompleteState> property of the <xref:System.Windows.Forms.BindingCompleteEventArgs> parameter.

 For more information about handling events, see [Handling and Raising Events](/dotnet/standard/events/).



## Examples
 The following code example demonstrates how to handle the <xref:System.Windows.Forms.Binding.BindingComplete> event.

## Remarks
 Use the <xref:System.Windows.Forms.BindingManagerBase> to iterate through a data-bound list by incrementing or decrementing the <xref:System.Windows.Forms.BindingManagerBase.Position> property. The <xref:System.Windows.Forms.BindingManagerBase> class is abstract. The <xref:System.Windows.Forms.CurrencyManager> class, which manages data-bound lists, inherits from the <xref:System.Windows.Forms.BindingManagerBase> class.



## Examples
 The following code example gets the <xref:System.Windows.Forms.BindingManagerBase> of every <xref:System.Windows.Forms.Binding> on the form, and prints the <xref:System.Windows.Forms.BindingManagerBase.Position> property for each <xref:System.Windows.Forms.BindingManagerBase>.

        <summary>Occurs when the property of a control is bound to a data value.</summary>
        <remarks>

## Remarks
 The <xref:System.Windows.Forms.Binding.Format> event is raised when data is pushed from the data source into the control. You can handle the <xref:System.Windows.Forms.Binding.Format> event to convert unformatted data from the data source into formatted data for display. When data is pulled from the control into the data source, the <xref:System.Windows.Forms.Binding.Parse> event is raised to unformat the displayed value, then the <xref:System.Windows.Forms.Binding.Format> event occurs to reformat the data for display. This ensures that the bound control displays correctly formatted data regardless of whether the user enters formatted or unformatted data in the control.

 The <xref:System.Windows.Forms.Binding.Format> and <xref:System.Windows.Forms.Binding.Parse> events allow you to create custom formats for displaying data. For example, if the data in a table is of type <xref:System.Decimal>, you can display the data in the local currency format by setting the <xref:System.Windows.Forms.ConvertEventArgs.Value> property of the <xref:System.Windows.Forms.ConvertEventArgs> to the formatted value in the <xref:System.Windows.Forms.Binding.Format> event. You must consequently unformat the displayed value in the <xref:System.Windows.Forms.Binding.Parse> event.

 The <xref:System.Windows.Forms.Binding.Format> event occurs whenever the <xref:System.Windows.Forms.BindingManagerBase.Current*> value of the <xref:System.Windows.Forms.BindingManagerBase> changes, which includes:

- The first time the property is bound.

- Any time the <xref:System.Windows.Forms.BindingManagerBase.Position*> changes.

- Whenever the data-bound list is sorted or filtered, which is accomplished when a <xref:System.Data.DataView> supplies the list.

 The <xref:System.Windows.Forms.Binding.Format> event also occurs after the <xref:System.Windows.Forms.Binding.Parse> event. For example, when a control loses focus, its contents are parsed. Immediately afterward, as new data is pushed into the control, the <xref:System.Windows.Forms.Binding.Format> event occurs allowing the new contents to be formatted.

 For more information about handling events, see [Handling and Raising Events](/dotnet/standard/events/).



## Examples
 The following code example creates a <xref:System.Windows.Forms.Binding>, adds a <xref:System.Windows.Forms.ConvertEventHandler> delegate to both the <xref:System.Windows.Forms.Binding.Parse> and <xref:System.Windows.Forms.Binding.Format> events, and adds the <xref:System.Windows.Forms.Binding> to the <xref:System.Windows.Forms.BindingsCollection> of a <xref:System.Windows.Forms.TextBox> control through the <xref:System.Windows.Forms.Control.DataBindings> property. The `DecimalToCurrencyString` event delegate, added to the <xref:System.Windows.Forms.Binding.Format> event, formats the bound value (a <xref:System.Decimal> type) as currency using the <xref:System.Decimal.ToString*> method. The `CurrencyStringToDecimal` event delegate, added to the <xref:System.Windows.Forms.Binding.Parse> event, converts the value displayed by the control back to the <xref:System.Decimal> type.

 This example assumes the presence of a <xref:System.Data.DataSet> named `ds`.

## Remarks
 Setting this property to `true` also enables error-handling behavior and causes the <xref:System.Windows.Forms.Binding.BindingComplete> event to be raised. The handler of this event can take the appropriate action, based on the success, error, or exceptions in the binding process, by examining the <xref:System.Windows.Forms.BindingCompleteEventArgs.BindingCompleteState> property of the <xref:System.Windows.Forms.BindingCompleteEventArgs> parameter.

## Remarks
 A binding is active when it meets these conditions:

- All its properties are set.

- The user did not call <xref:System.Windows.Forms.BindingManagerBase.ResumeBinding*> or <xref:System.Windows.Forms.BindingManagerBase.SuspendBinding*> on the <xref:System.Windows.Forms.BindingManagerBase> that the <xref:System.Windows.Forms.Binding> belongs to.

- The control to which the <xref:System.Windows.Forms.Binding> belongs has been created.

 A null value will be added to the data source when the control property is set to the object of <xref:System.Windows.Forms.Binding.NullValue*>. If <xref:System.Windows.Forms.Binding.NullValue*> is set to a string value, comparisons are case-insensitive.

## Remarks
 Raising an event invokes the event handler through a delegate. For more information, see [Handling and Raising Events](/dotnet/standard/events/).

 The <xref:System.Windows.Forms.Binding.OnParse*> method also allows derived classes to handle the event without attaching a delegate. This is the preferred technique for handling the event in a derived class.

## Remarks
 The <xref:System.Windows.Forms.Binding.Format> and <xref:System.Windows.Forms.Binding.Parse> events allow you to create custom formats for displaying data. For example, if the data in a table is of type <xref:System.Decimal>, you can display the data in the local currency format by setting the <xref:System.Windows.Forms.ConvertEventArgs.Value> property of the <xref:System.Windows.Forms.ConvertEventArgs> to the formatted value in the <xref:System.Windows.Forms.Binding.Format> event. You must consequently unformat the displayed value in the <xref:System.Windows.Forms.Binding.Parse> event.

 The <xref:System.Windows.Forms.Binding.Parse> event occurs under the following conditions:

- After the <xref:System.Windows.Forms.Control.Validated> event of the <xref:System.Windows.Forms.Control> occurs.

- When the <xref:System.Windows.Forms.BindingManagerBase.EndCurrentEdit*> method of the <xref:System.Windows.Forms.BindingManagerBase> is called.

- When the <xref:System.Windows.Forms.BindingManagerBase.Current*> of the <xref:System.Windows.Forms.BindingManagerBase> changes (in other words, when the <xref:System.Windows.Forms.BindingManagerBase.Position*> changes).

 For more information about handling events, see [Handling and Raising Events](/dotnet/standard/events/).



## Examples
 The following code example creates a <xref:System.Windows.Forms.Binding>, adds a <xref:System.Windows.Forms.ConvertEventHandler> delegate to both the <xref:System.Windows.Forms.Binding.Parse> and <xref:System.Windows.Forms.Binding.Format> events, and adds the <xref:System.Windows.Forms.Binding> to the <xref:System.Windows.Forms.BindingsCollection> of a <xref:System.Windows.Forms.TextBox> control through the <xref:System.Windows.Forms.Control.DataBindings> property. The `DecimalToCurrencyString` event delegate, added to the <xref:System.Windows.Forms.Binding.Format> event, formats the bound value (a <xref:System.Decimal> type) as currency using the <xref:System.Decimal.ToString*> method. The `CurrencyStringToDecimal` event delegate, added to the <xref:System.Windows.Forms.Binding.Parse> event, converts the value displayed by the control back to the <xref:System.Decimal> type.

## Remarks
 Use the <xref:System.Windows.Forms.Binding.PropertyName*> to specify the control property that you want to bind to a list in a data source. Most commonly, you bind a display property such as the <xref:System.Windows.Forms.Control.Text> property of a <xref:System.Windows.Forms.TextBox> control. However, because you can bind any property of a control, you can programmatically create controls at run time using data from a database.



## Examples
 The following code example prints the <xref:System.Windows.Forms.Binding.PropertyName*> value of each <xref:System.Windows.Forms.Binding> for each control on a form.
