WPF: One-way IValueConverter
ivalueconverter, wpf
Solution
All the examples from Microsoft simply throw a NotSupportedException or a NotImplementedException (the former makes more sense) from the `ConvertBack` method.
As you say, if the converter is one-way then chances are you'll be using it on a read-only control like `TextBlock`, so the `ConvertBack` method won't be getting called anyway.
Problem
From what I've been told, I need to create an `IValueConverter` to do my custom formatting. The problem is my formatting is one-way, there is no legitmate `ConvertBack` implementation. So, how do I handle one-way `IValueConverter`s. (If it helps, this is for a read-only control.)
