Add the e.OldValue property to the BaseContainerValidateEditorEventArgs class

created 12 years ago

It would be very convenient to have the OldValue property in the BaseContainerValidateEditorEventArgs class. For instance, it will be useful if it is required to determine dependencies between an old and new entered cell values.

    I wonder if anything will happen on this one? - it's been 4 years … :)

      Hi,

      At present, we do not have immediate plans to add this property. In any case, you can access an old value in the ValidatingEditor event handler by using the BaseEdit.OldEditValue property. For instance, if you are using a grid, the code should look like this:

      C#
      private void gridView1_ValidatingEditor(object sender, DevExpress.XtraEditors.Controls.BaseContainerValidateEditorEventArgs e) {  
    GridView view = sender as GridView;  
    BaseEdit edit = view.ActiveEditor;  
    object val = edit.OldEditValue;  
}  
      Visual Basic
      Private Sub gridView1_ValidatingEditor(ByVal sender As Object, ByVal e As DevExpress.XtraEditors.Controls.BaseContainerValidateEditorEventArgs)  
    Dim view As GridView = TryCast(sender, GridView)  
    Dim edit As BaseEdit = view.ActiveEditor  
    Dim val As Object = edit.OldEditValue  
End Sub
