Onvalidating in editorcontrol

Hi,

I made my own DataGridViewEditingControl, DataGridViewCell and DataGridViewColumn.
Is it possible to use an Onvalidating event in an editing control in a datagridview?
I wrote something like this:
Code:
Code:

Code:

---

Protected Overrides Sub OnValidating(ByVal e As System.ComponentModel.CancelEventArgs)
  MyBase.OnValidating(e)
  If Me.Text <> String.Empty Then
      If Me.Text <> "CORRECT"
        e.Cancel = True
      End If
  End If
End Sub

---

But when tabbing out the cell it gets executed twice plus that the incorrect value in the cell remains and the I can continue to edit in other cells.The event is correctly handled when I click somewhere else with the mouse (being the cursor remaining in the cell until a correct value is given).

Do I need to do something special when the tab key is pressed.

Any help is appreciated.

Thanks in advance.

The problem is that Tab is both an acceptable character in your editing control and a control key in the DGV. It may be as simple as excluding the Tab from your editing control (OnKeyDown filter, perhaps) so that it can act solely as a control key.
