When the Upload control is submitted on our website, the following alert popup message appears. Why is this, and how can I prevent it from happening so that the Upload control works as it should?

Thanks
Curtis

Hi JimB,

Please make sure that you have the Telerik.RadUploadProgressHandler. ashx registered in the web.config. In order to do that, please click on design view for the page that contains RadProgressManager, click on the manager's smart tag and select register RadUploadProgressHandler.

Hi JimB,

This issue happens because you are using right-button click on the control. Please use left-button click on the control's smart tag. I am sending you a screenshot as attachment how would it look like. For additional information please consult with this helpful article.

I am also getting this error, but could not resolve it. I moved from ASP.NET 2.0 to 4.0 on IIS7.0.
Here is complete error message

Page: /Claims/Telerik.RadUploadProgressHandler.ashx

Hello Nishat Mazhar,

To resolve this issue you need to turn off the "verify file exists" setting on the handler mapping in IIS7. In the UI, do this by double clicking on a handler, click on "request restrictions" and uncheck "invoke handler only if request is mapped to:".

Thanks for your reply. I gave that a try, however I don't get the options which you print-screened. Attached is what I get.

Hello JimB,

You need to add the RadProgressManager to your .aspx file.
After that, register the Telerk.Web.UI.RadProgressManagerHandler.ashx and RadUploadModule(with left button click on the smart tag(screenshot).

The reason why you got that error(described into your first post and the Nishat Mazhar's post) is because you don't have registered Telerk.Web.UI.RadProgressManagerHandler.ashx .
After the registration they should appear into your web.config file.
For more information see this help article.

Kind regards,

I've worked out why I couldn't register the handler and the module, and thats now been done. Cheers.

The error no longer appears, but the progress area doesn't appear! It just takes ages to process (like a normal FileUpload would do with such a large file).

Any ideas?

Thanks!

Hi,

Please make sure that the RadUploadProgressHandler is registered in the web.config file:
<httpHandlers>
  <add path="ChartImage.axd" type="Telerik.Web.UI.ChartHttpHandler" verb="*" validate="false" />
  <add path="Telerik.Web.UI.SpellCheckHandler.axd" type="Telerik.Web.UI.SpellCheckHandler" verb="*" validate="false" />
  <add path="Telerik.Web.UI.DialogHandler.aspx" type="Telerik.Web.UI.DialogHandler" verb="*" validate="false" />
  <add path="Telerik.RadUploadProgressHandler.ashx" type="Telerik.Web.UI.RadUploadProgressHandler" verb="*" validate="false" />
  <add path="Telerik.Web.UI.WebResource.axd" type="Telerik.Web.UI.WebResource" verb="*" validate="false" />
</httpHandlers>
