I moved my implementation to use Master Pages now the CheckedNodes.Count is always 0.The code is below.
It worked fine when it was on the same page. I don't have RadFormDecorator.
RadTreeView RadTreeView1 = (RadTreeView)Master.FindControl ("RadTreeView1");checkedCategories = RadTreeView1.CheckedNodes.Count;2 Answers, 1 is accepted

Hi Tony,
We are not exactly sure what might cause the issue. Could you please open a support ticket and send us a sample project which demonstrates the exact problem to examine it locally?
All the best,

I solved it. The problem was that I was initiating the call to do the count from a RadButtonBar on the MasterPage. It was Redirecting to the page that had the routine on it when I should have been using reflection to execute the routine. Below is the working example that solves the problem.
