dataGrid1 = gcnew DataGrid;
// Add the handler for the DataSourceChanged event.
dataGrid1->DataSourceChanged += gcnew EventHandler(
this, &Form1::DataGrid1_DataSourceChanged );
}
void DataGrid1_DataSourceChanged( Object^ sender, EventArgs^ /*e*/ )

}
private System.Windows.Forms.DataGrid dataGrid1;
private void CreateDataGrid()
{
dataGrid1 = new DataGrid();
// Add the handler for the DataSourceChanged event.
dataGrid1.DataSourceChanged += new EventHandler(DataGrid1_DataSourceChanged);
}
private void DataGrid1_DataSourceChanged(object sender, EventArgs e)
{
DataGrid thisGrid = (DataGrid) sender;
}
Private dataGrid1 As System.Windows.Forms.DataGrid
Private Sub CreateDataGrid()
dataGrid1 = New DataGrid()
' Add the handler for the DataSourceChanged event.
AddHandler dataGrid1.DataSourceChanged, AddressOf DataGrid1_DataSourceChanged
End Sub
Private Sub DataGrid1_DataSourceChanged(sender As Object, e As EventArgs)
Dim thisGrid As DataGrid = CType(sender, DataGrid)
