Thank you for contacting us.
This Dll (Telerik.Windows.RadUploadHandler.dll
) is located in the pack with our Silverlight controls just for our clients' convenience. I am confirming it is "a standard .Net framework dll and you should add it to your ASP.Net project and use it only from there
". This Dll contains code for the upload handler (RadUploadHandler) related to the RadUpload for Silverlight control.
Attached you can find an example with the RadUploadControl and the RadUploadHandler. Please preview it to figure out how to use it and where to reference it from. More about the RadUpload you can find in our Knowledge Base articles
We hope this information will help you. Of course if you have other RadUpload-related questions please do not hesitate to contact us again.
