c# DataGridView EditMode and DeleteKey

Question

c# winforms
My DataGridView has:
SelectionMode - CellSelect
EditMode - EditOnKeyStroke
It works well for all Keys except fot DeleteKey (when pressed - nothing happend).
I want - if DeleteKey is pressed - selected Cell (or Cells) stay selected, but - empty value (like in Excel).
Must I create a separate KeyDownEvent for DeleteKey only ?

Yes I think you will have to handle the KeyDown event to do that. Try something like the following: private void dataGridView1_KeyDown(object sender KeyEventArgs e) { if (e.KeyCode == Keys.Delete && dataGridView1.CurrentCell.Selected) { dataGridView1.CurrentCell.Value = null; e.Handled = true; } }

I'm not sure what the logic is behind this behaviour. If the entire cell is selected then pressing the 'Delete' key does nothing as you say. However if only the contents of the cell are selected then the 'Delete' key works as expected even without my code. It may be that in the first case the Delete key does nothing because you can't of course delete an entire cell - you can only delete its contents.

Vulpes Your code works asUsual. But I'm wondering about MSLogic. If dgv is in FullRowSelectMode - DelKey deletes selectedRow. If dgv is in CellSelectMode - it should be naturally to delete cellContent (or maybe cellItself). What does it mean that - DelKey - deletes Nothing ! Is there some hidenReason ? AnyWay - ThanksForYourCode.
