    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
