Define ScreenTipHelpUri in XAML

Posted 10 years ago by Eric P

Version: 15.1.0624

Is it possible to define the ScreenTipHelpUri in XAML? I have tried the following.

<Style TargetType="{x:Type ribbon:Button}" x:Key="BookmarkRibbonButtonStyle">
  ...
  <Setter Property="ScreenTipHeader" Value="bla" />
  <Setter Property="ScreenTipDescription" Value="bla" />
  <Setter Property="ScreenTipHelpUri" Value="http://somewhere.com/help" />
  ...
</Style>

I get a design-time XAML error that says "The method or operation is not implemented" for the Value of the ScreenTipHelpUri. When I look through the sample application I only see three places that the ScreenTipHelpUri property is used and its all in code not XAML.

Thanks

Hi Eric,

I believe it works fine to set a URL how you are doing even if VS complains. When we've done that in the past, I think it still had the value at run-time appropriately, meaning the warning is likely a VS bug.

Ok I feel a little stupid. I did not even thing to try and run the app. I saw the error and thought it would not compile. So the app does run and when I mouse-over the ribbon button I see the "Press F1 for more help" on the tooltip. So next question...pressing F1 does not do anything. I was assuming that it would open the default browser and navigate to the ScreenTipUri defined in the XAML. Is there another step I need to do (maybe in code) to get this to work?

Thanks

Hi Eric,

Check out the last section in the "Ribbon / Laout, Globalization, and Accessibility / Screen Tips" topic in the documentation. That talks about that ScreenTipUri property and how to handle it.

Great thanks. The sample code wires-up the ApplicationCommand.Help to a method handler in the code-behind. If I can figure out how to wire this up on my ViewModel I will be all set!

Thanks,

Hi Eric,

Since it's a routed command, you might have to have a related command handler in your view, and then call a method on your view-model in response.

So I found this blog (https://codingcontext.wordpress.com/2008/12/10/commandbindings-in-mvvm/) that talks about CommandBindings (plural vs. simple Command Binding) and MVVM and another link (http://matthamilton.net/commandbindings-with-mvvm) about the same topic. This looks promising. Maybe this information will be useful to someone else on the Actipro forums.

The latest build of this product (v25.1.0) was released 29 days ago, which was after the last post in this thread.
