Grid控件的操作

 grid_ItemDataBound(object sender, DataGridItemEventArgs e)中:

protected   void  grid_ItemDataBound( object  sender, DataGridItemEventArgs e)
     ... {
       //当为1时,显示已审,当为0时,显示未审
        foreach (DataGridItem a in grid.Items)

           ...{

                  a.Cells[15].ForeColor = System.Drawing.Color.Red;//把未审的颜色变成蓝色
                    a.Cells[16].Enabled = false;//修改和删除不可用
                    a.Cells[17].Enabled = false;
