I have a xaml file that I have bound a gridviewdatacolum width (GridViewLength) to an app.config file.  I have made the config setting a double, so the width in the xaml is expecting a converter.  It looks like one is built in, but it does not implement IValueConverter.  Am I missing something, or do I have to write my own converter?  If not, can I get an example of how to use the GridViewLengthConverter?
Thanks,
Anthony.
