Dynamic layer mapservice not displayed at runtime

[sapnas]

The WPF application displays the dynamic layer in VS Studio design. But when I run the app the dynamic layer does not appear on the map. The app does not generate any error and I'm unable to  narrow down the issue. Attached is the screen shot of design and runtime

Hi,

Please can you provide the XAML for the map portion of your application?

Cheers

Additional info, initially loads fine (this is intermiitent). When I maximize the application and zoom in the map the dynamic layers fails to load.

Ever resolve this?  I am experiencing the similar issue.............

In my situation I am connecting to a local ArcGIS Server using SQL Server DB.  In VS, I can see all features at layer selection time in the designer but when I run the application I only get a subset of the features.
