Onvalidating in editorcontrol

[styxke]

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:

 

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.
