I have a page with a RadTreeView and a user web control that contains an ASP:Button.

The button is disabled if none of the nodes in the RadTreeView are selected.

When the button is disabled, if I mouseover the button I get a DOM in jscript code:

Sys.ArgumentException: Value must be a DOM element
Parameter name: element

Line 5949 of ScriptResource.axd:

switch(Sys.Browser.agent) {
    case Sys.Browser.InternetExplorer:
        Sys.UI.DomElement.getLocation = function Sys$UI$DomElement$getLocation(element) {
            /// <param name="element" domElement="true"></param>
            /// <returns type="Sys.UI.Point"></returns>
            var e = Function._validateParams(arguments, [
                {name: "element", domElement: true}
            ]);
            if (e) throw e;

                        if (element.self || element.nodeType === 9) return new Sys.UI.Point(0,0);

                                                var clientRects = element.getClientRects();
            if (!clientRects || !clientRects.length) {
                return new Sys.UI.Point(0,0);
            }

     ...

Some code that demonstrates the issue. The code-behind class is empty.

    
            using System; 
        
            using Telerik.Web.UI; 
        
            public partial class SiteEdit : System.Web.UI.Page

            }
