Hello,

I am using RadAsyncUpload 2012.1.411.40.  I try to have OnClientProgressUpdating to create a custom progress bar.  When uploading a file under the Visual Studio Development Server, OnClientProgressUpdating is fired properly.  However, when uploading a file under a testing server(windows sever 2008), OnClientProgressUpdating is not fired at all in IE 9.  (I tired to upload a 80MB file.)  It actually works fine in Firefox in both servers.

I have set DisablePlugins to true for the RadAsyncUpload.  Will it cause the problem?  Does anyone have an idea?

Thank you,

Wai

Hello Wai,

DisablePlugins(true) forces the control to work with IFrame module so you need to register progress handler and upload module in you web config and add progressmanager on your page to work under IE.
Under all modern browsers the control use FileAPI and the progress monitoring works out the box.
