Hi,

I am trying to use RadAsyncUpload control in SharePoint but so far I am having no luck.

First of all, I have to say that I have found very little documentation to help me on this. I am currently stuck at a point where I keep getting the following error when I select a file:

Error: Unhandled Error in Silverlight Application Failed to Invoke: _onSilverlightError.   at System.Windows.Browser.ScriptObject.Invoke(String name, Object[] args)
   at UploadPrototype.EventManager.SilverlightError(String message, Int32 index)
   at UploadPrototype.MainPage.<>c__DisplayClass1f.<ProcessResponse>b__18()

I have uploaded a screenshot that shows where exactly the error is thrown in ure JS. I have also uploaded a screen shot that shows the UI.

Can you please clarify what I need to do to get this to work in SharePoint 2010? What changes do I need to make to the Web.Config?

Thanks

Hello Richard,

Please make sure that you have the following handler registered in the handlers section of the web.config:

<add name="Telerik.Web.UI.WebResource"

path="Telerik.Web.UI.WebResource.axd" verb="*"

type="Telerik.Web.UI.WebResource, Telerik.Web.UI, Culture=neutral, PublicKeyToken=121fae78165ba3d4"/>

If you are using IIS6.0 or the Visual Studio integrated server the registration should go the HttpHandlers section. In that case the registration should look like:

<add path="Telerik.Web.UI.WebResource.axd" type="Telerik.Web.UI.WebResource, Telerik.Web.UI, Culture=neutral, PublicKeyToken=121fae78165ba3d4" verb="*" validate="false"/>

I have added it and I am getting the same error (version of telerik 2012.1.501.35):

Hello Richard,

This error tells you that there is no handler registered in the web.config, hence the control complains and says "Not Found". Please make sure that the handlers are registered because this is the only reason AsyncUpload will throw such error.

In order to verify that the handler is registered try to access the Telerik.Web.UI.WebResource.axd handler the following way:

http://localhost/{Your web site name}/Telerik.Web.UI.WebResource.axd?type=rau

An error screen displaying

{ "message" : "RadAsyncUpload handler is registered succesfully, however, it may not be accessed directly." }

should pop up (because there are no files uploaded, this is just a test request). Is this the case?

It comes up with an error complaining that the telerik dll was not found. However I did a further search and found this:

http://www.telerik.com/help/aspnet-ajax/introduction-troubleshooting.html

Which states that if the telerik DLL is in the GAC then the handler needs to be registered like this:

<add name="Telerik.Web.UI.WebResource" path="Telerik.Web.UI.WebResource.axd" verb="*" type=

"Telerik.Web.UI.WebResource, Telerik.Web.UI, Version=[ASSEMBLY_VERSION], Culture=neutral, PublicKeyToken=121fae78165ba3d4"

/>

So I made this change:

<add name="Telerik.Web.UI.WebResource" path="Telerik.Web.UI.WebResource.axd" verb="*" type="Telerik.Web.UI.WebResource, Telerik.Web.UI, Version=2012.1.501.35, Culture=neutral, PublicKeyToken=121fae78165ba3d4" />

And now it works. I really think this needs to be documented more comprehensively as it has taken me weeks to figure this out when the only thing I was missing was a version number.
