ListBoxSelectionMode.One/DEL key in GDBG

[Administrator]

Hi Stefan

When I set the ListBoxSelectionMode.One in a GDBG, the delete key will remove the whole row. How can I change the behaviour of the del key that I''m able to delete the selected text in a grid cell while editing the cell?

Thomas,

there are two options:

1) Set ActivateCurrentCellBehavior & GridCellActivateAction.SetCurrent) != 0)

- or -

2) override HandleBoundCurrentCellKeyDown and check for e.KeyCode == Keys.Delete and don''t call base class.

Right now this is the code that gets excecuted in GridDataBoundGrid.HandleBoundCurrentCellKeyDown

			else if (e.KeyCode == Keys.Delete)
			{
				GridRangeInfo range = Selections.Ranges.ActiveRange;
				if (range.IsRows || range.IsTable)
				{
					if (Model.Options.ListBoxSelectionMode != SelectionMode.None
						&& CurrentCell.IsEditing
						&& (Model.Options.ActivateCurrentCellBehavior & GridCellActivateAction.SetCurrent) != 0)
						return;
					if (range.IsRows)
					DeleteRecordsAtRowIndex(range.Top, range.Bottom);
					else if (range.IsTable)
						DeleteRecordsAtRowIndex(Binder.ListManagerPositionToRowIndex(0), Binder.ListManagerPositionToRowIndex(Binder.RecordCount-1));

					e.Handled = true;
				}

Additionally you should also handle either the OnKeyDown or OnClearingCells event for the case that you press DELETE when the current cell is not in edit mode.
