AjaxManager trying to find un-related and un-rendered control?

[Marval Group]

Hi

We have a page using a Prometheus RadAjaxManager control. In simple terms it looks like this:

	<RadAjaxManager>
	<AjaxSettings>
	<AjaxSetting AjaxControlID="controlOne">
	<UpdatedControls>
	<AjaxUpdatedControl ControlID="controlOne" />
	<AjaxUpdatedControl ControlID="controlTwo" />
	</UpdatedControls>
	</AjaxSetting>
	<AjaxSetting AjaxControlID="controlTwo">
	<UpdatedControls>
	<AjaxUpdatedControl ControlID="controlOne" />
	<AjaxUpdatedControl ControlID="controlTwo" />
	</UpdatedControls>
	</AjaxSetting>
	<AjaxSetting AjaxControlID="controlThree">
	<UpdatedControls>
	<AjaxUpdatedControl ControlID="controlThree" />
	</UpdatedControls>
	</AjaxSetting>
	</AjaxSettings>
	</RadAjaxManager>

At certain times controlOne and controlTwo may be hidden and only controlThree shown. However when controlThree makes a callback we get the following JS alert message:

Sys.InvalidOperationException: Could not find UpdatePanel with ID 'controlOnePanel'. If it is being updated dynamically then it must be inside another UpdatePanel.

Any advice appreciated, thanks.

Hi marvalbloke,

I suggest that you wrap your "controlThree" into a regular asp:Panel control which is always visible and add it to the ajax settings instead controlThree:

1 <RadAjaxManager>
2     <AjaxSettings>
3         <AjaxSetting AjaxControlID="controlOne">
4             <UpdatedControls>
5                 <AjaxUpdatedControl ControlID="controlOne" />
6                 <AjaxUpdatedControl ControlID="controlTwo" />
7             </UpdatedControls>
8         </AjaxSetting>
9         <AjaxSetting AjaxControlID="controlTwo">
10             <UpdatedControls>
11                 <AjaxUpdatedControl ControlID="controlOne" />
12                 <AjaxUpdatedControl ControlID="controlTwo" />
13             </UpdatedControls>
14         </AjaxSetting>
15         <AjaxSetting AjaxControlID="Panel1">
16             <UpdatedControls>
17                 <AjaxUpdatedControl ControlID="Panel1" />
18             </UpdatedControls>
19         </AjaxSetting>
20     </AjaxSettings>
21 </RadAjaxManager>
22 <asp:Panel runat="server" ID="Panel1">
23     place controlThree here and change its visibility but leave the Panel1 as always visible
24 </asp:Panel>

Let me know if this works for you.

Andrew,

I had a similar problem as in this post

http://www.telerik.com/community/forums/thread/b311D-bgeked.aspx

What worked for me was to add the controls to the AjaxProxyManager in the code behind when need like so:

AjaxSetting

ajaxSetting = new Telerik.Web.UI.AjaxSetting("RadAjaxManager1");

ajaxSetting.UpdatedControls.Add(

new AjaxUpdatedControl("ProductList", "RadAjaxLoadingPanel1"));

AjaxManagerProxy1.AjaxSettings.Add(ajaxSetting);

The AjaxManager is on the main page whith the Productlist in the usercontrol
