Hi,

I have a silverlight 4 webpart in sharepoint 2010. I'm trying to access it with Telerik testing framework. I'm using the following code.
Settings mySettings = new Settings(new Settings.WebSettings(BrowserType.InternetExplorer));
 mySettings.Web.EnableSilverlight = true;           
 
Manager myManager = new Manager(mySettings);
myManager.Start();
 
myManager.LaunchNewBrowser();
AddDialogSupport(myManager);
 
Thread.Sleep(mySettings.Web.SilverlightConnectTimeout);
 
var slApp = myManager.ActiveBrowser.SilverlightApps()[0];            \\ this is where i get the error
 
myManager.Dispose();

 

I'm getting the following exception when i execute the Manager.ActiveBrowser.SilverlightApps()[0] line.

ApplicationNotReadyException.
Error checking HTML access on SilverlightApp.

ExecuteCommand failed!
InError set by the client. Client Error:

System.InvalidOperationException: Javascript call [document.getElementsByTagName(\\'object\\')[0].settings.enableHtmlAccess] failed!

Any help would be appreciated.

Hello Arooj,

Basically the error message is trying to say that it could not find the Silverlight application on the web page. There are a couple of possible reasons for this:

1) The browser did not navigate to the right page with your Navigate call
2) The Silverlight application is actually contained inside an <iframe> element. If this is the case you need to access the frame first then the app like this:

var slApp = myManager.ActiveBrowser.Frames[0].SilverlightApps()[0];

That is assumeing Frames[0] is the correct frame. It could be Frames[1] or 2. Depends on which frame the Silverlight application was placed on. By looking at the HTML source you should be able to discover which one is the right one.
