Examples

void button1_Click( Object^ /*sender*/, System::EventArgs^ /*e*/ )
{
   try
   {
      // Get the 'BindingManagerBase' Object*.
      BindingManagerBase^ myBindingManagerBase = BindingContext[ myDataTable ];

      // Remove the selected row from the grid.
      myBindingManagerBase->RemoveAt( myBindingManagerBase->Position );
   }
   catch ( Exception^ ex ) 
   {
      MessageBox::Show( ex->Source );
      MessageBox::Show( ex->Message );
   }
}

private void button1_Click(object sender, System.EventArgs e)
{
   try
   {
      // Get the 'BindingManagerBase' object.
      BindingManagerBase myBindingManagerBase=BindingContext[myDataTable];
      // Remove the selected row from the grid.
      myBindingManagerBase.RemoveAt(myBindingManagerBase.Position);
   }
   catch(Exception ex)
   {
      MessageBox.Show(ex.Source);
      MessageBox.Show(ex.Message);
   }
}

Private Sub button1_Click(sender As Object, e As EventArgs)
   Try
      ' Get the 'BindingManagerBase' object.
      Dim myBindingManagerBase As BindingManagerBase = BindingContext(myDataTable)
      ' Remove the selected row from the grid.
      myBindingManagerBase.RemoveAt(myBindingManagerBase.Position)
   Catch ex As Exception
      MessageBox.Show(ex.Source)
      MessageBox.Show(ex.Message)
   End Try
End Sub

Remarks

The RemoveAt method relies on the underlying data source to determine how the method behaves. (See the Binding class for a list of supported data sources.) For classes that implement IList, IBindingList, or ITypedList, as well as strongly typed classes that implement IList, the RemoveAt method actually deletes the row in the underlying list instead of removing its contents.

If the underlying list implements the IBindingList interface, the AllowRemove property must return true. If the underlying list implements the IList interface, the IsFixedSize property must return false.
