Found the following interesting discussion in the Newsgroups:
Datagrid (windows forms)
by:Anonymous
| is there like a BeforeColumnEdit() or BeforeRowEdit() event in the datagrid.
i want to disable a command button when a row in the grid is dirty. (i.e. a column is being currently edited) and enable it after the Changed() or Validated event fires
i tried the RowChanging(), ColumnChanging() events. but it didnt work.

| | | Hi,
I would add a handler to the datagridtextboxcolumns textbox
textchanged and validating events to enable or disable the command buttons.
Dim colName As New DataGridTextBoxColumn
With colName
..MappingName = "LastName"
..HeaderText = "Name"
..Width = 100
End With
AddHandler colName.TextBox.TextChanged, AddressOf TextBox_TextChanged
AddHandler colName.TextBox.Validating, AddressOf TextBox_Validating
Private Sub TextBox_Validating(ByVal sender As Object, ByVal e As
System.ComponentModel.CancelEventArgs)
Debug.WriteLine("Validating")
End Sub
Private Sub TextBox_TextChanged(ByVal sender As Object, ByVal e As
System.EventArgs)
Debug.WriteLine("Text changed")
End Sub
Ken
