Tab and "DroppedDown" Combo Box

[georg]

Hello All,

Im having a bit of trouble with tabbing and the dropped down combo box (within a datagrid).

e.g.

ColumnComboBox.DroppedDown = True

and

 Protected Overrides Function ProcessCmdKey(ByRef msg As System.Windows.Forms.Message, _
        ByVal keyData As System.Windows.Forms.Keys) As Boolean
            Explanation: This will turn the enter key into a tab key

            If msg.WParam.ToInt32() = CInt(Keys.Enter) Then
                SendKeys.Send("{Tab}")
                Return True
            End If
            Return MyBase.ProcessCmdKey(msg, keyData)
        End Function ProcessCmdKey

The problem is, that when I select an item in the dropped down portion of the ComboBox, and then hit Enter (which is processed as a Tab), the Text Box "underneath" the ComboBox doesnt collect the new entry.

So, I guess my question is really: How do I "get at" the selected item in the ComboBox which inherits the Text Box in the datagrid?

Thanks,

georg
