Can not find ressource "SyncToBoxTemplate"

[Andi]

Hi there,

in relation to your online demo I have built a grid with syncronisation between a TextBox an the GridCells. It works fine and I decided to add theese grid to a greater application.
In this application I can't get it to work.  I just get an error the ressource "SyncToBoxTemplate" will not be found.
What does I've done wrong? I have copied the code 1:1

ok, I have found the failure in my Code.
I have two constructors. One for a new, empty Grid and one which loads content into the grid.
In the second one I forget to call the InitializeComponent - method.
