RadWindow as Controls Container

Regarding this demo: http://demos.telerik.com/aspnet-ajax/window/examples/internalcontent/defaultcs.aspx

I do not see what mechanism causes a click on the grid row item to post back and update the content of the detailsview. How does it work? How can I do something similar, to send an ID to a RadWindow so it can pull data from a database and populate itself?

You might be better served to ask this over on the RadControls forums.

May be.  But the controls came with Sitefinity, and I'm using them on a Sitefinity site.  The fact that my example is from the controls portion of their web site doesn't seem revelent.

Its done with the RadAjaxManager at the top...see how it links the radgrid and the details view (which lives in the window) together and visa versa? ...so also notice the grid has postback set on client row click.  So you click a row, posts back, sets a session variable, and the details portion is databound to that session item.

What is it you need to do?...grid editing?  There are much more elegant (and faster) solutions for stuff like that.
