Silverlight - Radupload Issue with Importing file

Question

Hi All,

I am using Silverlight + Rad controls.

I am implementing Import functionality. I have used Radupload control (Telerik.Windows.RadUploadHandler).

When i am going to import file. But suppose the file is already open. Then it is throwing error that "process can not access the file, it is being used by another process".

I am trying to catch the error but not success.

The error is out of control.

Can anyone plz guide me?

Thanks, Mahesh.
