I need to set DefaultImageSrc of a tree item (and other things that support images) to reference an icon in a different xap. THe xap is loaded into my app. (xap1 has the UI, xap 2 has the data model indicating data to be shown by the UI)

My app successfully loads multiple xaps

THe UI is managed in xap1 (all calls to telerik code are there)

The other xaps provide data for the UI to work on (they know how to fetch the data, format it etc).

I want the data xaps to be able to provide icons for the objects they manage and hand off to the UI layer. Concrete example. I want the RadTreeItems to have data specific icons. The icon is a part of the data xap that provides the data objects. I dont see how to refer to them

I must go



What is the correct syntax of this string that would allow me to refer to an icon in a xap that is not the one that contains this code

Hi Paul,

You can use the approach that is demonstrated in the blog post Peter reffed you to. Basically you can access the stream of the image from the second xap and use it to create a BitmapImage. Then you can set the RadTreeViewItem.DefaultImageSource to the BitmapImage.

I attached a sample project demonstrating this approach. Please make sure that the SilverlightApplication8.Web project is marked as start-up project and the SilverlightApplication8TestPage.aspx page is the start-up page.

Examine the solution and let us know if it helps.

Kind regards,
