Hello, guys.
In my application I added loading panel on client PageLoad event as it was described on this forum.
            function pageLoad(sender, eventArgs) {
                if (!eventArgs.get_isPartialLoad()) {
                    $find("<%= RadAjaxManager1.ClientID %>").ajaxRequest("PAGE_LOAD");
                }
            }
But after I added some ajax requests to my code I found that the panel used as updated control gets redrawn each time (to be exact not, each but starting from second time and I think thi is a kind of bug) I perform ajax request.
I tryed to remove the ajax setting made to AjaxManager in a design time using the following code
        bool Stop = false;
        foreach (AjaxSetting Setting in RadAjaxManager1.AjaxSettings)
        {
            if (Setting.AjaxControlID == RadAjaxManager1.ID)
                foreach (AjaxUpdatedControl Ctrl in Setting.UpdatedControls)
                    if (Ctrl.ControlID == pnlSplash.ID)
                    {
                        Setting.UpdatedControls.Remove(Ctrl);
                        Stop = true;
                        break;
                    }
            if (Stop)
                break;
        }

but it didn't help. It still appears during ajax requests made from client code.
What have I done wrong?

With respect, Sergey.

Hello Batoha,

If I understand correctly your requirements you need to show loading panel only on PageLoad of the page and not on each AjaxRequest. Could you please test the approach provided in the following help topic and verify if this works for you.

Hello, Maria.
The approach you advised is what I used on my page.
But as we know, when we add something to AjaxManager as an updated control it will be updated if its so to say "master" AjaxContol requested any ajax update. In the propesed case I added pnlSplash as an upated control to the AjaxManager itself.
After that AjaxManager will update pnlSplash in any case is I make any call to $find("<%= RadAjaxManager1.ClientID %>").ajaxRequest("SOME_KIND_OF_ANYTHING");
That is what I want to avoid with pnlSplash. I do not want it to be updated after initial load. So I tryed to remove it from AjaxManager's updated controls but with no success. That caused my question.

With respect, Sergey.
