Hello Manish,

Take a look at the following help documentation which explains how to check file size from client side.
Checking File Size on the Client.

Hi,

Thanks for your reply. But I have already mentioned in my post that i am not using

RadProgressArea

and you told me example of that. So please tell me about that what i have asked.


Please help.


Thanks

Hello Manish,

To Princy's point, you can't check the file size of a file in RadUpload, when using javascript, without the use of RadProgressArea. That is the only way you can do it.

Hello Manish,

Kevin is correct. RadUpload control is using a standard input type="file" control. With it is not possible to check the file size client-side. To validate the file size on the client please use the RadAsyncUpload control.
