Examples
The following example assigns the CurrentCell property of a System.Windows.Forms.DataGrid to a DataGridCell. The value stored in the DataTable is returned by specifying DataRow and DataColumn objects through the RowNumber and ColumnNumber properties.
void PrintCell( Object^ sender, MouseEventArgs^ /*e*/ )
{
DataGrid^ thisGrid = dynamic_cast<DataGrid^>(sender);
DataGridCell myDataGridCell = thisGrid->CurrentCell;
BindingManagerBase^ bm = BindingContext[ thisGrid->DataSource,thisGrid->DataMember ];
DataRowView^ drv = dynamic_cast<DataRowView^>(bm->Current);
Console::WriteLine( drv[ myDataGridCell.ColumnNumber ] );
Console::WriteLine( myDataGridCell.RowNumber );
}
private void PrintCell(object sender, MouseEventArgs e)
{
DataGrid thisGrid = (DataGrid) sender;
DataGridCell myDataGridCell = thisGrid.CurrentCell;
BindingManagerBase bm = BindingContext[thisGrid.DataSource, thisGrid.DataMember];
DataRowView drv = (DataRowView) bm.Current;
Console.WriteLine(drv [myDataGridCell.ColumnNumber]);
Console.WriteLine(myDataGridCell.RowNumber);
}
Private Sub PrintCell(sender As Object, e As MouseEventArgs)
Dim thisGrid As DataGrid = CType(sender, DataGrid)
Dim myDataGridCell As DataGridCell = thisGrid.CurrentCell
Dim bm As BindingManagerBase = _
BindingContext (thisGrid.DataSource, thisGrid.DataMember)
Dim drv As DataRowView = CType(bm.Current, DataRowView)
Console.WriteLine(drv(myDataGridCell.ColumnNumber))
Console.WriteLine(myDataGridCell.RowNumber)
End Sub
Remarks
You can use the ColumnNumber value to specify a DataColumn in the DataTable associated with the System.Windows.Forms.DataGrid control.
