Hi telerik,

Wanted to know if the upload control for silverlight has a built in mechanism to check if the file uploaded to the server is completely intact and the same exact file both on the client and server. 

Thanks!

Hi JDT,

We don't have such functionality enabled in the control itself, but we have the needed events and the infrastrucure for users to extend it and to provide such check. You can make a crc checksum and to pass it as a parameter to the upload handler and to compare. We are not aware of a tool that will create the crc checksum of a file in silverlight. You can check this .net tool, but it will require a Silverlight porting to be used in SL app:

Please check the following help articles for using the events and passing the parameters.

Please let us know how it goes.

Valentin,

Thank you for your response. I can't implement your suggestion since I can't access the file locally. Please see my post 


Regards.
