      myTableStyle->MappingName = "Orders";
      myColumnStyle = gcnew DataGridTextBoxColumn;
      myColumnStyle->MappingName = "Orders";
      myColumnStyle->HeaderText = "Orders";
      myTableStyle->GridColumnStyles->Add( myColumnStyle );
      myDataGrid->TableStyles->Add( myTableStyle );
      myColumnStyle->MappingNameChanged += gcnew EventHandler( this, &MyForm::columnStyle_MappingNameChanged );
      flag = (bool *)true;
   }

   // MappingNameChanged event handler of DataGridColumnStyle.
   void columnStyle_MappingNameChanged( Object^ /*sender*/, EventArgs^ /*e*/ )
   {
      MessageBox::Show( "Mapping Name changed" );
   }

private void AddCustomColumnStyle()
{
   DataGridTableStyle myTableStyle = new DataGridTableStyle();
   myTableStyle.MappingName = "Orders";
   myColumnStyle =  new DataGridTextBoxColumn();
   myColumnStyle.MappingName="Orders";
   myColumnStyle.HeaderText="Orders";
   myTableStyle.GridColumnStyles.Add(myColumnStyle);
   myDataGrid.TableStyles.Add(myTableStyle);
   myColumnStyle.MappingNameChanged+=new EventHandler(columnStyle_MappingNameChanged);
   flag=true;
}
// MappingNameChanged event handler of DataGridColumnStyle.
private void columnStyle_MappingNameChanged(object sender, EventArgs e)
{
   MessageBox.Show("Mapping Name changed");
}

Private Sub AddCustomColumnStyle()
   Dim myTableStyle As New DataGridTableStyle()

   myDataGrid.TableStyles.Add(myTableStyle)
   AddHandler myColumnStyle.MappingNameChanged, AddressOf columnStyle_MappingNameChanged
   flag = True
End Sub
