I am facing an issue while using RadUpload control.
The control Select file button gets disabled and is not available to user at times. This happens randomly and there is no fixed pattern. We have the following code available on all our pages.

protected

void _DisablePageCache()

{

Response.Expires = -1;

Response.ExpiresAbsolute =

DateTime.Now.AddHours(-48);

Response.Cache.SetCacheability(HttpCacheability.Private);

Response.CacheControl =

"no-cache";

Response.Cache.SetNoStore();

}

The resolution to this takes us to clean browser cache which rectifies the issue and allows user to again upload by clicking on select button. An urgent solution to this problem will help a lot.

Thanks
Bhawesh

Hi Bhawesh Kumar,

There was a problem with the Select button in versions prior to Q2 2009. It has nothing to do with the server side code but with incorrect positioning of the hidden input file that actually takes care of the upload process. Unfortunately the only two resolutions to this problem. The first is to upgrade to the latest version of the RadControls (this is Q2 2009). Another solution is to disable the input skinning. This can be achieved with setting the EnableEmeddedStyleSheets property of the RadUpload to false.
