This error might be accure by varios reasons.

1. Check whether you are trying to upload a document with size more than 4 MB. Refer this link.
2. Also check the size of the ViewState of your page. If the ViewState has a larger size, it might cause this error to occur. Check this thread.

Also check your network connectivity.

Use FileUpload control. (if are working with .netframeworkd 2.0)

Thanks to all,
I used fileupload control & in webconfig file I simply add <httpRuntime maxRequestLength ="45600"/>
& Finally I can upload files without any error.

Thanks!
