Hi,

First add a tablestyle to the datagrid then I would add a handler to
the datagridtextboxcolumns textbox validating event.

Add Tablestyle

Add a handler to the textbox validating event


Dim colDescription As New DatagridTextboxcolumn

With colDescription

..MappingName = "Notes"

..HeaderText = "Notes"

..Width = 350

End With

AddHandler colDescription.TextBox.Validating, AddressOf CellValidating



Private Sub CellValidating(ByVal sender As Object, ByVal e As
System.ComponentModel.CancelEventArgs)

Debug.WriteLine(DirectCast(sender, DataGridTextBox).Text)

End Sub

Mike,

I am glad that you make this mistake as well, I think more than a year ago I
gave this answer as well and than I got the only answer from Ken something
as.

"Does not work with a datagrid"

You cannot add a handler to the cells in a datagrid to write something more
than he did.

Or do you have some code.

You can develop a your own DataGridTextBoxColumn inherited from
DataGridTextBoxColumn to do whatever you want.
