I have a page with a RadAjaxUpdatePanel that may or may not show a RadListView control depending on what the user selects. The radlistview is on the page, but initially is Visible=false.
This scenario will result in a javascript error Sys.ArgumentUndefinedException in the asp.net ajax framework.
Do you know of a workaround for this control?

Hello Adam,
I have prepared a simple test page which illustrates a scenario similar to yours and works as expected on my end. Please try it out and let me know how to alter it in order to replicate the problem you are experiencing.
Kind regards,

Adam,
If the problem is exhibited in SharePoint 2010 and you are displaying the RadListView as a result of an AJAX request, you should know that this is an unsupported scenario due to a SharePoint limitation, which prevents the Javascript files of script controls to be registered on the page after AJAX requests. If this is the case, then keep all script controls visible on the page, or show them via regular postbacks.
All the best,

It turns out my asp:ScriptManager had EnablePartialRendering set to true. When I set this to false, the javascript errors went away.
