Hi,
I have been unsuccessful in obtaining a reference to the RadWindowManager via the GetRadWindowManager or the $find() calls.
$find returns null and GetRadWindowManager returns undefined.
Any help would be greatly appreciated.
Thanks in advance,
Robert

Hello Robert,
You need to make sure that the page will be fully loaded and the RadWindowManager is rendered on the page before you call the Javascript.
In ASP.NET AJAX environment this can be done by registering to the Sys.Application.load() event:

I'm having the same problem as stated above, but in my case I am creating a server control that will load a RadWindow. The page the server controls is on has a RadWindowManager on it. I can't get access to the RadWindowManager through script, it keeps coming up undefined. I tried the suggestiong to use the Sys.Application.add_load, but now I'm getting an error that 'Sys' is undefined.
Any ideas?

Solved my own problem. Was trying to inject the script by RegistringClientScriptBlock. That did not work, I just added the script to a label control added to the page.

I had similar symptoms (everything was returning undefined or null) and came across this thread, but nothing was helping.
My problem was a really simple stupid one: All the objects need to be inside the <form> tags (RadWindowManager, RadScriptManager, and any calls to Sys.Application.add_load()). Other javascript can be outside of it, it seems, but not the Sys calls.
A previous developer who worked on this page that I am trying to convert to the ajax controls combined the page with the master page code, and what they ended up doing is putting all the master page code outside of the <form> tags.
Posting here to hopefully remind anyone of this possibility if they run into a poorly pieced together page like I did here.
