[Solved] GridViewGroupRow Frozen Columns and Expander Path goes missing

[Richard]

Hi 

I have implemented a group row template from the GroupFooterInGroupHeader example.  I have modified it so its fit my needs, but I just noticed if I scroll the Expand Button goes off the screen.  The columns I have frozen stay.  Enclosed screen shot shows the before and after.  If I click in the same area it still expands and collapses.

So my question is how do I get the this column frozen inside the template as well?

Regards
