Hello,

I try to change the DataTemplate for the DataErrorContentTemplateKey. The only thing I need to do is to change the border color to red.

I think I miss where I have assign it to the DataGrid. Reshaper also tells me, that the template is never used. Can someone help me?
oizControls:OizDataGrid is just a wrapper for XamDataGrid.
