Setting design time data for a binding that uses a value converter

Hi,

I am trying to set up sample data to be used while I design a UI. I have successfully achieved this by using the tools in blend to create sample data based on my ViewModel.

For simple bindings this has worked perfectly, but I can not figure out how to set up the sample data to display when a value converter is used.

The bindings (even with converters) all work perfectly at run time.

I decided that copying my code here probably wouldn't help but if there is anything you need or want to see, let me know!

Any help anyone could offer would be great and thanks in advance.

Daniel
