Cancel Ajax Request?

[Robert]

I have the following on a page:

radscriptmanager
radajaxpanel
radajaxloadingpanel
button

I wire everything together, click the button and the loading panel displays the image as expected.  However say on the server a process is running very long and I want the user to be able to kill the request.  I don't mean a timeout I want to be able to kill the ajax request by maybe clicking a button embedded within the radajaxloadingpanel.  

Can you tell me if this is possible?

Hello Robert,

I would suggest you to review the following help topic which elaborates on canceling Ajax request. Give it a try and let me know if it helps.

Well.. that's not exactly related but here is the solution:

<script type="text/javascript">

    function CancelAjaxRequest() {

        var obj = Sys.WebForms.PageRequestManager.getInstance();

        if (obj.get_isInAsyncPostBack())

            obj.abortPostBack();

    }

</script>

Put this in a RadAjaxLoadingPanel template:
<asp:button runat="server" onclientclick="CancelAjaxRequest(); return false;"></asp:button>
