- Resize based on WindowContent
 - Disable Scrollbars

I'm trying to display a RadWindow that when it loads will resize based on the size of the content inside the RadWindow iframe.  

After it has been resized to fit the content I would like to disable the scrollbars for that iframe.

Below is a sample of the javascript I've got so far but am having trouble disabling the scrollbars

function GetSelectedWindow()
{
    var oManager = GetRadWindowManager();
    return oManager.getActiveWindow();
}

ChangeSize()
{
    var oWindow = GetSelectedWindow();
    var width = oWindow._iframe.contentWindow.document.body.scrollWidth;
    var height = oWindow._iframe.contentWindow.document.body.scrollHeight;
    oWindow._iframe.style.overflow = 'hidden';        //doesn't work
    Window._iframe.scrolling = 'no';                      //doesn't work
    oWindow._enablePageScrolling(false);               //doesn't work
    oWindow.setSize(width, height);
}

I am using the RadTree in the ASP.NET AJAX Toolkit and have run into a problem.  I cannot use the tri-state functionality for certain situations in my code and must use a custom JavaScript function to uncheck parent nodes when the child node is unselected.  I found this snippet in the knowledge base.  Unfortunately it does not work as promised. 

When I run this code it unchecks the parent node but also unchecks all of the current nodes siblings.  I put an alert function in the while loop and found that it returns a message that says “I am unchecking  undefined”.  What am I missing?  Thank you.

function clientNodeChecked(sender, eventArgs)

        {

           var node = eventArgs.get_node();  

           alert("I am unchecking " + node.Text);    

            if (!node.get_checked())

            {      

                while (node.get_parent().set_checked != null)

                {

                    node.get_parent().set_checked(false);

                    node = node.get_parent();

                    alert("I am unchecking " + node.Text);

                }

            }

        }
