Web: ASP.NET AJAX

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.

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(); ...

This has been something like a tale of the unexpected for me. A client recently reported a problem with scrolling being slow in IE when the mouse wheel is used. It took about two afternoons of testing different scenarios and head scratching, and this is where we got: it seems that if a :hover pseudo CSS class is used on the web page, scrolling in IE7 becomes slower, even if the CSS selector, which contains the :hover pseudo class does not select anything, i.e. the CSS rule is not relevant to any of the web page elements.
