ASP.NET MVC Tip #41 – Create Cascading Dropdown Lists with Ajax In this tip, I demonstrate three methods of creating cascading drop down lists in an MVC application. First, I demonstrate how to write JavaScript code to update one dropdown list when another dropdown list changes. Next, I show you how you can retrieve the data for the dropdown lists from either a controller action or a web service. A reader of this blog emailed me recently and asked how he could create cascading dropdown lists in an MVC application. Why would you want to create cascading dropdown lists? Imagine that you want a user to select a car make and model. You display a dropdown list of car makes. Each time a user selects a new car make, a dropdown list displaying car models is populated (see Figure 1). Figure 1 – Cascading DropDown...(read more) 9/6/2008 8:56:26 PM

Microsoft Extensibility Framework released on CodePlex I am super jazzed that we released the Microsoft Externality Framework CTP2 on CodePlex.  http://www.codeplex.com/MEF     We have taken a lot of good feedback in from the community... a few cool things here:   1. We shipped source code! 2. We have a complete set of developer Overviews ,  guidelines and samples . 3. Because of community feedback, we now support constructor injection 4. MEF itself is now more extensible... For example, want POCO ?, no problem, you can easily write an extension to store the customer attribute metadata in an external file.    More to come here, but it is a solid start! 5. Lots of API cleanup based on feedback..   Related, we also recently updated  Framework Design...(read more) 9/6/2008 12:10:01 AM

MvcFutures And ASP.NET MVC Beta Wanted to provide a quick heads up about the MvcFutures assembly within ASP.NET MVC CodePlex Preview 5 . As mentioned in various places, this assembly contains various experimental features we are considering for future versions of ASP.NET MVC. When we release the BETA for ASP.NET MVC, it will not automatically be included in the project template by the installer. We’ve included it in the various previews for convenience, but we want the BETA installer to be as close to the RTM installer experience as possible. We will make sure that the assembly remains available on CodePlex . I just wanted to make you aware of this so there is no surprises when we release the Beta regarding this. Thanks!

Firefox, ClickOnce, XBAPs and .NET 3.5 SP1 One of the things that I noticed immediately when I made the SmallestDotNet was that Firefox was reporting the version of the .NET Framework installed. There's a Firefox extension that is installed with .NET 3.5SP1. I was stoked about this because I'd like users of BabySmash to be able to use ClickOnce from Firefox to launch it. ClickOnce and Firefox When you install .NET Framework 3.5SP1, there's a key written to the registry whether Firefox is installed or not. If Firefox is installed later, it will notice the key and use the plugin. If it's already installed, it'll just work. The registry key points to a Firefox Extension (XPI) that acts like the 3rd party FFClickOnce extension that a lot of us installed before. The registry...(read more) 9/5/2008 3:21:49 PM
