Weird RadAjaxManager Behavior

[Virgil Rodriguez]

Hi all,

What would cause program execution to keep switching between a Page_Load event and a RadAjaxManager_AjaxRequest event ? And sometimes even a function and a RadAjaxManager_AjaxRequest event?

I experience this when I try to debug my program, and as I am stepping through it, line execution keeps switching from one to the other. And not only that, after completing one round of switching between Page_Load and RadAjaxManager, the whole process is repeated not once, not twice, but at least 3-4 times.

Although I still get my desired results, without any noticeable delay, it sure is so much inefficient and very confusing to debug.

I would have wanted to paste my actual code but it is too big. I'm just wondering why this is happening and what should I consider doing so that the execution is more efficient and predictable.

Any feedback or help would be appreciated.

Thanks,

Hello Virgil,

When ajax request is performed the Page_Load is event is fired as in the case of regular postback. And the RadAjaxManager AjaxRequest event is fired when you have called the ajaxRequest() client-side method of RadAjax. A possible reason for the multiple page executions is if you have invoked a few ajax requests from the client for instance as below:

<script type="text/javascript">
function InitiateRequests()
{
    var manager = $find("<%= RadAjaxManager1.ClientID %>");
    manager.ajaxRequest("args");
    manager.ajaxRequest("args");
    manager.ajaxRequest("args");
}
</script>

Could you please check if this is the case?

Any additional information on your scenario might help us get to the source of the issue.
