BindingGroup stop controls from updating

Mar 19, 2009 at 3:36 AM

When I add a BindingGroup ValidationRules, my DataRows are nolonger updated. I have Grid that provides the DataContext for my text controls. It is bound to a ComboBox, which in turn is bound to a DataTable. This all works fine. Even my database gets update. But no validation. So I added a BindingGroup to my Gird and now nothing is updated. Not even the current DataRow. My BindingGroup is:




                      <db:BookCaseValidationRule />




Is not this the way to get row level validation?
