Going through my WPF backblog...
I use this post as a bookmark as much for myself as for others.

How to show different text based on an enum value?
This question was asked on the MSDN forums, so I thought I'd replciate it here for everybody's benefit.
When you want to bind to a value that's an enumeration, sometimes you want to show specific text. While writting a converter is one way of solving this problem, it requires writting code. And no code is of better quality than the one you don't write.
So here's the sample I posted.
MainWindow.xaml:
1 <Window x:Class="MsdnForums.TextBlockBoundToEnum.MainWindow"
2 xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
3 xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
4 xmlns:local="clr-namespace:MsdnForums.TextBlockBoundToEnum"
5 Title="TextBlockBoundToEnum" Height="300" Width="300"
