Help Please! VSM Storyboard Events not Firing

09-11-2008 1:41 PM |

I'm trying to write my first custom control utilizing the VisualStateManager for events. The control displays properly, but the storyboards wired via VSM do not fire. Could someone please review this generic.xaml and tell me where I've gone wrong?

Thanks in advance for any help you can provide.

Are you sure the right template is being applied?

It does indeed appear that the correct template is being loaded. The control is properly rendered. It's just that none of the events fire. Here's a snippet of the underlying custom control class.

[TemplateVisualState(Name = "Normal", GroupName = "CommonStates")]

[TemplateVisualState(Name = "MouseOver", GroupName = "CommonStates")]
