I submitted a bug report, but thought I'd post this here too in case anyone else is having this problem.

The issue is only with build 2009.1.311.

If you try to iterate through the nodes of your treeview to determine the checked nodes text &/or value, this functionality has broken since the previous builds.

I.E. This code used to work:

    
            string selected = "";  
        
            foreach (RadTreeNode node in RadTreeView1.CheckedNodes)  
        
              {  
        
                 if ((node.Checked == true) && (node.CheckState != TreeNodeCheckState.Indeterminate))  
        
                 {  
        
                    selected += node.Text + ",";  
        
                 }  
        
              }

RadTreeView1.CheckedNodes would properly return the number of checked nodes. In 2009.1.311 however this always returns 0 therefore it will never run the code to determine what is checked.

The only solution for the moment is to revert back to a previous build.

Posted to my support ticket, but for everyone elses benefit:

The main difference is mine happened to exist within a master page. If I tested my control outside of this setup then it worked as expected.

I've commented out practically everything in my masterpage and I've narrowed it down to the root cause.

The issue exists with the RadFormDecorator control.

If you add one on the page then the problem appears. This appears to have cropped up in the 2009.1.311 build, because it worked perfectly fine with the BETA build. And I know some changes had been made to the RadFormDecorator control. Whatever it was broke this functionality. Disabling this from my masterpage instantly made my controls return values from checkboxes but of course I lost all my decorations.

For now I will continue using the BETA dll until this problem can be patched. Please notify and send me an unofficial build when this gets fixed for me to test out.
