Hi!
I'm testing my site until I received the following error:
"Sys.WebForms.PageRequestManagerServerErrorException: An unknown error occurred while processing the request on the server. The status code returned from the server was: 0"

The error started to appear when I put my RadGrid(sortable) inside a Radpanel and put a Radloading panel. The error appears whenever I try to click any navigation button while the RadLoading panel is loading.
Can anyone tell what does this error means, what its cause, and how to fix it?

Thanks!

I am getting the exact error only on Chrome and Safari, when using RadAjaxPanel

I tried to trace this, but it happens exactly after i set the onclick property of a button inside the RadAjaxPanel.

any help?

Ah, 

I am not the initial poster

anyhow, i thought that the code will not be useful in my case since i am not using a Grid.

i will check it
