Unable to disable AJAX for a RadUpload in a nested user control

[Dave]

I have a user control that consists of a RadUpload, RadProgressManager, RadProgressArea, and a button.  This user control is nested in another user control which is ajaxified by a RadAjaxManager.  I've scoured the forums and tried everything I came across, including adding a call to __doPostBack() and adding a handler to the RadAjaxManager to disable AJAX when my button raises the event.  My click event doesn't roll up to the outer user control or the page its on.  Any suggestions??? I can provide code if necessary, but I think my description makes the scenario clear.  Thanks!!

Hello Dave,

You can try to attach an event handler (the below mentioned conditionalPostback function) to the OnRequestStart event of the RadAjaxManager control. Here is the client-side function that you will need to implement:

function conditionalPostback(sender, args) {
         if (args.get_eventTarget().indexOf('submit button id') > -1) {
             args.set_enableAjax(false);
         }
     }

Kate,

Thanks for your reply.  I have tried to implement that exact conditionalPostback function with no success.  The wrench in the gears is that this request originates from a user control that is nested within another user control that is placed on a page have a RadAjaxManagerProxy that is attached to a Master Page with the RadAxajManager.  I cannot even add any JavaScript to the markup of my user control directly without it causing an error.  When I try adding this function using RadScriptManager.RegisterStartupScript, the function never even gets triggered.  I suspect this is because the RadAjaxManager cannot be found in the user control because it sits 3 levels above it.  Do you have any other suggestions?

Hello Dave,

Have you tried the following in your user control:

RadAjaxManager.GetCurrent(Page).ClientEvents.OnRequestStart =
"function(sender,args){if (args.get_eventTarget().indexOf('Button1') > -1) { args.set_enableAjax(false);}}";

I hope that helps.

Cori,

Thanks for the reply.  I did try that, to no avail.  I ended up re-architected the app so I could meet my deadline.  I did want to leave this thread open though in case anyone else has this problem.

Hi Ben,

Try using the following in your user control:

protected void Page_Load(object sender, EventArgs e)
{
ClientScript.RegisterClientScriptBlock(Page.GetType(), "manager", string.Format("window['managerId'] = '{0}'", RadAjaxManager.GetCurrent(this).ClientID), true);
}

<script type="text/javascript">

Sys.Application.add_load(function {$find(window["managerId"]).OnRequestStart = function(sender, args) {
if (args.get_eventTarget().indexOf('submit button id') > -1) {args.set_enableAjax(false);}};});

</script>

Kind regards,
