PopupButton not disabled when generated by DataTemplate - Ribbon for WPF Forum

Environment: Windows 7 (64-bit)

Hi,
I am trying to use databinding to dynamically generate the controls on my ribbon. I have found a problem where a PopupButton doesn't get automatically disabled when its PopupContent is set to a Menu which has an an ItemsSource binding and an ItemTemplate.

E.g.


<r:PopupButton Label="Bound" Command="NotACommand">
  <r:Menu ItemsSource="{Binding Items}">
    <r:Menu.ItemTemplate>
      <DataTemplate>
        <r:Button Context="MenuItem" Label="{Binding}" />
      </DataTemplate>
    </r:Menu.ItemTemplate>
  </r:Menu>
</r:PopupButton>

I have emailed a sample showing the problem to support.

Hi Phil,

In that scenario the visuals can't be found since they are dynamically created so we can't check them like we can in the scenario where you explicitly give the controls as popup children. As a workaround, you can give another Command (instead of NotACommand) and have that command's CanExecute return true/false based on the state of the commands on your buttons.

Thanks, that works great. Is there any way the command on a PopupButton can be executed, or does it only use CanExecute?

Hi Phil,

I believe it will fire that command when the popup is first opening from a click. But you should really only use the command for a PopupButton to control its enabled state.
