Strobe Symbol Migration from Silverlight 4 to WPF

Question

Hello,

I have migrated my Silverlight 4 WbeMapping application to WPF. I am having trouble migrating my Strobe symbol. The xaml works but when the strobes are flashing it slows down the application to a crawl. I am trying to convert the strobe symbol from XAML to C# to see if that will help. The code I have so far will display the point but the animations are not working. I have attached the screen shots of the code. Any help would be much appriciated.

You can look at the following Microsoft documentation about animation in WPF http://msdn.microsoft.com/en-us/library/bb613592.aspx. Animating 2000 features is expected to slow down your application. You can google about Hardware Acceleration for WPF, this might help improve performance.

Jennifer,

Thanks for the code. What I was looking for was using the Selected attribute not so much the MouseOver. I switch the VisualState to Selected and that works fine. The issue I am having is if I place 2000 points on the map and have them all flash at the same time the application slows down to a crawl. Is this a known WPF or ESRI bug or should the app be able to handle 2000 flashing points at a time?

V/R,

Josh

You can download WPF Interactive SDK from http://help.arcgis.com/en/webapi/silverlight/help/index.html#/Sample_Interactive_SDK/01660000000v000000/ You will notice that SL and WPF are not very much alike with their Storyboard, specifically how they define their TargetProperty.
