title: MVC View Page should hide while Partial View (AJAX) Loading
body: <p>I have a drop down list, when I change the drop down list a telerik tree will be loading which is in a partial view and ajax loading bar appears in the tree content only. But I want to disable the page (user should not be able to use the page but he should see the page) while the content is loading and show the user a "loading....." screen.</p>
