For those of you looking to learn or hone your fundamental WPF skills, I thought you might find this video beneficial. It’s a nice 11-12 minute video on what you can do with IValueConverter by the lovely Beth Massi. The video goes through an example of IValueConverter in VB.NET, but they also have some C# code to download if you like. Check it out:

The IValueConverter interface is very handy when you want to convert or format a given object to your specifications, and in Beth’s example she also displays how you can use it to verify and do type validation of user edited data.
