Te class in ExtendingGraphBehavior

Nov 14, 2009 at 4:04 PM

I see the http://www.mscui.net/Blog/2009/04/default.aspx

In "Create a new class using Visual Studio called DateFormatConverter:", I would like to know what is IValueConverter?

Because there are some problem with it.

When I debug, it show that: Can not find the type or namespace name IValueConverter' (Are you missing using directive or component reference?)

So, how can I solve the problem?
