[Solved] GridviewExpressionColumn incompatible w/ Domaindatasource

[david mcintyre]

The gridviewexpressioncolumn doesn't seem to work if the gridview's itemssource is a Domaindatasource.  It blows up on me w/ a Keynotfoundexception.  I've tried adding column (just the column, no expression) in xaml and codebehind, after the grid is loaded, etc but to no avail.  Is there  a way to do this?  The weird thing is that I *have* been able to do this in one user control in my project where i never get an error, but in another user control i always get the error.  I can't find any meaningful differences between teh two samples on why it works in one case and not the other.

Hello david mcintyre,

 What sort of Expressions do you use? Would it be possible for you to prepare a small sample application and attach it in a separate support ticket so that we may inspect this locally?

Best wishes,
