Question

I’m just starting to get my hands dirty with silverlight and “value converter” keeps popping up. I don’t remember reading about them in the ASP.NET web app world. Is this something special in Silverlight/WPF? What is its purpose?

Thanks!

From this excellent post:

When you’re binding data to controls there will be times when the data needs to be modified or tweaked some on the way into a control or as the data leaves a control and goes back to the source property (during a TwoWay binding for example).  Sure, you can always write code to change a given value, but in many cases it’s much easier to write a simple value converter instead that can be re-used.  In this post I’ll walk through creating a value converter and then show the code for a few of the value converters I find myself using fairly frequently.
