NodeExpand not firing with LoadOnDemand after website moved to another machine

[Polaris431]

I use LoadOnDemand and the NodeExpand event on the server-side fires. When I move my application to my Test server, the event never gets fired. When you click on the plus sign to expand the node, there is a slight pause and then the "Loading..." message next to the node flashes very quickly. On the Test server, I re-installed the Telerik controls using the setup application and when I use the demo application that is part of the install, the NodeExpand does work there. It just doesn't work in my application. I compared my app's web.config file with the demo but couldn't see any difference, although I only compared items that began with the word "Telerik". Another thing that might be related to the problem is that the Font type for my RadMenu is not the same as the font on my development server. I don't set the font at all. I use the "Default" skin. The font on the Test server looks like Times New Roman whereas on my machine it looks more like Sans Serif. The following are some details about my setup:

* Test server is Windows 2003
* Telerik.Web.UI is installed in the website's bin directory on Test server and is version 2008.1.619.35

The treeview is set as follows:

 

<telerik:RadTreeView ID="RadTreeView1" runat="server" Width="100%" Skin="Sunset" Font-Size="12px" OnClientNodePopulationFailed="TreeviewPopulateError" OnNodeExpand="RadTreeView1_NodeExpand" OnClientNodeClicking="TreeviewClick" OnClientDoubleClick="TreeviewDoubleClick" CheckBoxes="true" OnClientNodeChecked="TreeViewCheck" PersistLoadOnDemandNodes="false" EnableViewState="false" OnClientNodeExpanding="toggleHandler" OnClientNodeCollapsing="toggleHandler" OnClientNodePopulated="OnClientNodePopulated"> 

 

</telerik:RadTreeView> 

 

Thanks for your help

Problem solved. The version on my machine was 2008.1.515.35. I copied that to the Test server and this fixed the problem.
