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:

      <Grid.BindingGroup>

            <BindingGroup>

              <BindingGroup.ValidationRules>

                      <db:BookCaseValidationRule />

             </BindingGroup.ValidationRules>

          </BindingGroup>

      </Grid.BindingGroup>

Is not this the way to get row level validation?
