I am currently testing out Trial versions of the ASP.Net AJAX Rad Controls and the RadControls for Silverlight. I have the following in the Visual Studio 2010 project
- Silverlight 4 Application (SL App) with a RadChart in it.
- ASP.Net User Control with a reference to the the SL app: <object data="data:application/x-silverlight-2," ...> ... </object>
- Master Page including the RadScriptManager
- ASP.Net form with related RadComboBoxes and the above user control
I was trying to refresh the RadChart in the SL App with value from the selected values in the ASP.Net AJAX RadComboboxes. I figured out how to pass parameters to the SL App. However, with the SL App present on the page, the RadComboBoxes do not drop down. Is this a known issue? Is there a fix or a workaround?
I've attached a simpler version of the project for your reference. The outcome is the same whether I use a Master Page or not.
Thank you,
Wes C.
