out of the range

Hi Nietzsche, Based on the call stack it looks like there is a current record that was marked modified. Does it help if you set Table.CurrentElement = null; - or - Table.CurrentRecordManager.Navigate(null); - or - Table.CurrentRecordManager.Reset(); before you set the datasource to null.

I tried the solutions you proposed, but they doesn''t work. I send a sample. If You delete the last record the exception raised. Waiting for one answer. Thanks of everything.

Sample WindowsApplication15_7859.zip

This code seems to delete the row fro me in your sample.

private void grdResult_TableControlCellButtonClicked(object sender, GridTableControlCellButtonClickedEventArgs e)
{
	e.TableControl.Table.GetCurrencyManager().Position -= 1;
	oCol.RemoveAt(e.Inner.RowIndex-2);
	grdResult.Engine.Table.TableDirty = true;
	grdResult.Refresh();
}
