RadUpload Error

[Freak]

Hi,

Sometimes i am facing this issue with rad upload control, when some postback already happened on the page.

The error says:

Radupload ajax callback error. Source url returned error: 500
Internal Server Error
../Telerik.RadUploadProgressHandler.ashx?RadUrid=addfddd-wefd-dffd-ddffddfdffs

Did you register the RadUploadProgressHandler in web.config?

I have registered the module and handler as below in web.config:

<modules runAllManagedModulesForAllRequests="true">
      <add name="RadUploadModule" type="Telerik.Web.UI.RadUploadHttpModule, Telerik.Web.UI" preCondition="managedHandler"/>
    </modules>
    <validation validateIntegratedModeConfiguration="false" />
    <handlers>
      <add name="Telerik.RadUploadProgressHandler.ashx_*" path="Telerik.RadUploadProgressHandler.ashx" verb="*" type="Telerik.Web.UI.Upload.RadUploadProgressHandler, Telerik.Web.UI" preCondition="integratedMode,runtimeVersionv4.0"/>
      <add name="Telerik_Web_UI_WebResource_axd" verb="*" preCondition="integratedMode" path="Telerik.Web.UI.WebResource.axd" type="Telerik.Web.UI.WebResource" />
      
    </handlers>
