RadAjaxManager causes RadTreeView not to fire.

[Diorelle]

Hi,

I am having some issues with getting the RadTreeView and RadAjaxManager to work. After the page loads for the first time, I am still able to collapse/expand the RadTreeView that I've added on the page. As soon as I select and item from the dropdownlist to update the RadTreeView, it no longer allows me to expand/collapse or even click the the nodes. I don't get any errors either.

Note that the code below is inside a ".ascx" file which will be used as a SharePoint webpart. I am currently using VS2010, .NET Framework 3.5, MOSS 2007.

Please help.

Thank you so much!

Hi Diorelle,

Could you please add a setting in the RadAjaxManager in which the RadTreeView updates itself and verify if this makes any difference. Like this:

<AjaxSettings>
        <telerik:AjaxSetting AjaxControlID="RadTreeView1" >
          <UpdatedControls>
                <telerik:AjaxUpdatedControl ControlID = "RadTreeView1" />
            </UpdatedControls>
        </telerik:AjaxSetting>
</AjaxSettings>

Best wishes,
