So it looks like the expander column is the culprit and I also couldnt find a way to bind to the checked items in the inner gridview in row details.

I solved this but in a kind of round-about way.

Basically I templated the gridview control (using Blend) in order to see the inner status bar controls (paging, refresh button)

I then built a gridview with rowdetails using the silverlight toolkit, the added that and the intersoft status bar to a grid in order to replicate the Intersoft gridview.

It actually works pretty well and looks almost the same. No plus sign for expanding the controls but oh well, it works..

Reply if you want some code.

Ah, I see..

In order to get the tilda to work you need to change the ImagesDirectory (in Designer UI) to the directory with your images.

IE..

ImagesDirectory = ~/img/

then set your splitterimage (or whatever) directly.

splitterleft = newImage.gif

Answered my own question.

Replace "Page.FindControl" with  "WebPaneManager.FindControl"
