Problem using Enter key with DataGridView control

Hi guys,
I have a DataGridView control that is not bound to any underlying data, as I handle that manually.

If I enter some text into a DataGridView cell and press Tab key the focus changes to the next cell and if I also enter some text into that cell a new Row is automatically added to the control.

If however I enter some text into a DataGridView cell as before but press Enter key instead of Tab, the contents of that cell is basically lost and no new row is added.

I was hoping to create a new Row whether I press a Tab or Enter keys. Is that possible and if so, how can I do that?

The thing is that the application I have is getting fairly large so it's not so easy to extract code but I'll tell you a bit more of what's going on and what I've tried.

I handle DataGridView events such as CellBeginEdit, CellValidating, CellValueChanged, CellClick, CellEnter. For example when I click on a cell I get events such as CellClick and CellBeginEdit. After entering some text if I press Tab key I get CellValidating event but if I press Enter instead, I don't get CellValidating event.

Sorry for not being able to send you code, as it's scattered and fairly extensive, but I hope the above paragraph gives you a bit more info, even though it's not very much.

If you want me to try something and let you know of the result I'd be happy to do that ?

As you may know it's dificult to help you that way but I will try.

If your problem is when you're editing the cell and press enter key instead of tab you can do this (in the snippet) to change the behavior of the handle keys. This overrides the ProcessCmdKey() changing the TAB key with ENTER key. Maybe this way all the events that you use now keeps running.

I really don't understand why the CellValidating is not running ... it should work on bouth examples that you give me.

Check if this heps
   Protected Overrides Function ProcessCmdKey(ByRef msg As System.Windows.Forms.Message, ByVal keyData As System.Windows.Forms.Keys) As Boolean
        If keyData = Keys.Enter And Me.DataGridView1.IsCurrentCellInEditMode Then
            SendKeys.Send("{TAB}")
            Return True
        Else
            Return MyBase.ProcessCmdKey(msg, keyData)
        End If
    End Function
