[Solved] wierd issue with radtabs, radmultipage, and prometheus ajax manager

[Joshua Gates]

I have a form within a master page.
It contains a RadtabStrip with Rad-Multi page views assigned.
In one page view i have a webusercontrol.
i ajaxed the tabs to the tabs...and the tabs to the multi-page

all teh tabs work with exception of  the one with the webusercontrol.
the web usercontrol contains a Prometheus upload and prometheus grid.
If i remove the ajax setting from the proxy manager everything works great.but i get a full page post back.

if i add in the ajax settings for the above..i get the contents of that tab ajax'd. how would i go about saying that tab contents is not ajax'd

Hello Joshua,

You can try Ajaxifying the whole RadtabStrip. Also, in order to rule out any improper control settings, you can nest the whole control in an AjaxPanel. Alternatively, if this does not help, you can open a formal support ticket, and send us the problematic code, in the form of a small working project, for further investigation.

i tried nesting the control on that one pageview in an ajaxpanel and setting its enableajax to false so that control would not have any ajax functionality...but i get js error popup saying object reference not set to instance of object...and then the control never loads...as well as the tab never gets selected.

Hi Joshua,

At this point, I would suggest that you open a formal support ticket, and send us a small working project, which demonstrates the problem. We will debug it locally, and advise you further.

I'm also gettting a JS popup stating that an object reference not set to an instance of an object.

This is occurring on a page I have with a RadTreeView and the RadTreeViewContextMenu.  I have a RadAjaxPanel and originally it was not surrounding the TreeView, but I tried that and I'm still getting the same problem.

If I comment out the RadAjaxManager, then everything works, just with full postbacks.  When I uncomment it, I get the JS popups.

I should also note that this is a control, ascx, file and that I'm currently working through several controls to upgrade from a previous version of RadControls.  The whole process has caused me some confusion as I feel like I'm having to dig for upgrade info from several different places so it's very possible I'm missing something.

What should I be looking for?  I'm completely stuck.

Thanks in advance for your help.

Okay, I figured it out.  Turns out I had both the RadAjaxPanel and the RadAjaxManager on the page.  This was the original setup of this page (I'm updating the controls from a RadControls (non-ajax) so I didn't realize this was a problem.  As soon as I removed the RadAjaxManager, all seems to be working correctly.
