Loading Panel not loading

[Nicholas Walker]

I have a situation like this:

I have my base page object.

Inside of my base page I have an ajax Manager.
Inside of base page I have a user control
Inside of this user control I have another user control with a radajaxmanagerproxy
Inside of this user control I have a RadGrid
For my edit form settings I have using EditFormType="WebUserControl"
Inside of that control I have a radajaxmanagerproxy

This radajaxmanagerproxy will not show the loading panel when an ajax postback occurs.

The page other then this works great, but for some reason the loading panel will not show.

Also during some release possibly the 2008 Q2 this worked perfectly.  I believe after upgrading to 2008 Q3 it stopped, and we never noticed.

Do you have any guidelines for nesting radajaxmanager(proxy) like this in order to get my desired outcome?
Are there any debugging points that you can suggest?

We are now on 2008 Q3.  We have not upgraded to 2009 Q1 yet.

Hi Nicholas,

Could you please elaborate a bit more on your scenario? Do you have separate RadAjaxLoadingPanel in the user control used as grid edit form? Can you try removing the RadAjaxManagerProxy control from the above mentioned user control and add the ajax settings programmatically on Page_Load or Page_PreRender as described here and see if it makes any difference?

Check it out and let me know how it goes.

Kind regards,

Nicholas, were you ever able to resolve this issue?  I've been having a similar issue where the ajax on the page works fine; however, the loading panel never shows up.

I have a base page with an ajax Manager and a loading panel
inside the page I have a user control
this user control contains a radajaxmanagerproxy that contains a RadGrid (loading panel shows up for typical grid operations)
the grid edit form loads another user control that that has a radajaxmanagerproxy

Whenever performing any operation on the user control for the edit form that is setup for ajax the ajax works but the loading panel never shows up.  I've tried using the loading panel on the page, just using the ID, and also adding a seperate loading panel on this user control itself to no avail. 

Is there any known issue with using the loading panel where the controls are nested like described above and there are mutiple levels of ajax settings?  I've tested this with both Q3 2008 and the new Q2 2009.

Any help would be appreciated

Thanks
Matt

Hi MD,

I followed your description and prepared a sample project for you. Please try it on your end and let me know how it works.
Note that if the user controls are loaded on demand, as the grid edit form, I suggest that you add the ajax settings in the user controls in code behind, on Page_PreRender instead of using RadAjaxManagerProxy.
