Hello Son,

You can create a DelegateCommand and do something in its Execute method and then call RadUpload.CancelUpload(). This command, you can set to the RadUpload.CancelCommand property, and the command will be triggered when the Cancel button is pressed.

Hi Son,

I attached a sample illustrating Alex's suggestion. The Telerik DelegateCommand provides a simple ICommand implementation. If you need more info about implementing command binding in Silverlight, you can have a look at this article.

Hi Tina
Thank you for your repply.
I was talking about "Cancel" button in File Open Dialog which is showed when you click on "Browse" button in RadUpload control. Maybe we have a confusion about this. And I apologize about that confusion.
Please help me again.

Hi Son,

There is nothing exposed for the cancel button of the open file dialog. The upload control will only prepare files when the file dialog returns positive result.
