Loading Panel not showing consistently

[Jeff Nafe]

We have a page that primarily features a RadScheduler control. Certain actions fire an Ajax request and we refresh the Scheduler in these cases. The Scheduler always refreshes properly, but the Loading Panel only shows occasionally. I haven't been able to determine a set pattern in terms of when it shows/doesn't show yet. I believe that I have the controls set up properly. Has anyone else ran into an issue like this before? I have tried to set up events for RequestStart and RequestEnd which manually hide/show the loading panel and this works a little better, but still not consistently. Any tips would be appreciated! Below is a sample of the code that I'm using.

    <telerik:RadAjaxManager ID="ajxmgr" runat="server" OnAjaxRequest="ajxmgr_AjaxRequest"
        UpdatePanelsRenderMode="Inline">
        <AjaxSettings>
            <telerik:AjaxSetting AjaxControlID="ajxmgr">
                <UpdatedControls>
                    <telerik:AjaxUpdatedControl ControlID="rdScheduler" LoadingPanelID="lpMdl" />
                    <telerik:AjaxUpdatedControl ControlID="control1" />
                    <telerik:AjaxUpdatedControl ControlID="dtPckr" />
                </UpdatedControls>
            </telerik:AjaxSetting>
            <telerik:AjaxSetting AjaxControlID="rdScheduler">
                <UpdatedControls>
                    <telerik:AjaxUpdatedControl ControlID="RadCalendar1" />
                </UpdatedControls>
            </telerik:AjaxSetting>
        </AjaxSettings>
        <ClientEvents OnRequestStart="RequestStart" OnResponseEnd="ResponseEnd" />
    </telerik:RadAjaxManager>
    <telerik:RadAjaxLoadingPanel ID="lpMdl" runat="server" Transparency="20" BackColor="#E0E0E0"
        IsSticky="false" InitialDelayTime="100">
        <div class="ldpnl">
            Please Wait...
            <br />
            <img src="images/icons/ajax-loader2.gif" alt="loading..." style="padding-top: 15px;" />
        </div>
    </telerik:RadAjaxLoadingPanel>

Thanks!

UPDATE: I haven't completely fixed my issue yet, but I have followed some tips given by Telerik in response to a support ticket that I opened for this issue.

It looks like much of this issue is caused by a stylesheet that is included. I'm not sure what part exactly (most of this stylesheet was a skin that was actually created by Telerik for us), but when I comment out the stylesheet, the loading panel works much more consistently. Also, the loading panel is displaying on top of a Scheduler control. Removing the custom skin from that control also seems to help. So, for anyone else having this issue, I would suggest trying these things first to see if they help the issue.

Hello Jeff Nafe,

I managed to trace the reason for the loading panel not displaying to the fact that at times the ajax request ends within the InitialDelay time span set for the loading panel. Under this circumstance, this behavior is expected. Therefore, in order to avoid this problem you need to either decrease the initial delay time interval or just remove it.

I hope this helps.

Hi,

I also had the same problem. When I turn on IsSticky , the loading panel appears. But due to IsSticky(I guess) the loading does not fill the entire screen. Can anyone help me with this....?

Hello Jeff,

It is hard to determine what the cause for this issue is without taking a look at your implementation.. Please, open up a formal support ticket and send your files for debugging on our side (it will be great if you make a runnable test project).

Thanks in advance.

Best wishes,
