If you are using asp:HiddenField controls (rendered as <input type="hidden" />) in your website and update their values with AJAX requests, you may observe some unexpected changes in the page layout in Internet Explorer (IE). It will seem that an empty line is inserted at each location where a HiddenField control resides. The behavior is observed only in IE and looks like a problem caused by the browser or the MS AJAX client-side framework. A quite easy workaround for this glitch is to wrap the HiddenField in a container with no height and reduced font size. Here is an...

While working on a recent "real" project for Telerik, I used the RadTabStrip for ASP.NET AJAX to provide users with a list of content they could navigate. It was simple enough. A RadTabStrip with a few tabs, a RadMultiPage holding each tab's content, and content on each pageview that linked to new pages in the website.

When we have a running application and we want to show a modal dialog window what we generally do is more or less the following: var window = new MyDialogWindow(); window.ShowDialog();   Doing that works great - the dialog window shows and is modal. It has just one tiny defect - if you switch from the running application to another one (i. e. using Alt + Tab) and then come back to the running app the modal dialog window is not showing and the app is inactive. The solution - just assign the parent window to the Owner property of your modal dialog window :  var window = new MyDialogWindow(); window.Owner = this;  window.ShowDialog(); ...
