Stopping drag and drop

[Mike Woolley]

Hi,

I''d like to prevent any form of drag and drop on the grid. I''ve set AllowDragSelectedCols and AllowDragSelectedRows to false and also tried setting GridOleDataSourceMouseController.HitTestSelectionEdge to 0 and large values, but with no luck. How do I prevent the ''arrow with box'' cursor from appearing?

Thanks once again.

In the designer, under the ControllerOptions property, uncheck the OleDataSource flag. Or, from code, try

//C#
this.gridControl1.ControllerOptions = GridControllerOptions.All & (~GridControllerOptions.OleDataSource);

''VB.NET
Me.gridControl2.ControllerOptions = GridControllerOptions.All And Not GridControllerOptions.OleDataSource

Thanks. Is it possible to do this on a row-by-row basis, i.e. enable drag and drop from the grid only for the currently selected row?

You can try handling QueryCanOleDragRange and cancel it if you do not want to allow the e.Range to be dragged.

private void gridControl1_QueryCanOleDragRange(object sender, GridQueryCanOleDragRangeEventArgs e)
{
	if(!(e.Range.IsRows && e.Range.Top == this.gridControl1.CurrentCell.RowIndex && e.Range.Height == 1))
	{
		e.Cancel = true;
	}
}
