This morning, I had the chance to play around with another ASP.NET AJAX control: the CascadingDropDown control. Like the name implies, it's a nifty little AJAX-enabled control that dynamically enables and populates a DropDownList based on the value selected in a previous list. Kinda like the coding version of those old skool "Choose Your Own Adventure" books.You've seen this kind of thing in action plenty of times, I'm sure. Remember the last time you filled out a registration form that had you pick a country, then you suddenly had a "State/Province" list that only included regions within that country?
