I have a wpf datagrid with a master/detail defined. I have a control in the grid and it needs to know the a value from the current row (I can get this ok) but it also needs the container row to make a calculation.

Bit like an "Order/Order Detail" where the price calculation on the order detail requires the order type from the header.

 I override the CommittingNewItem, CreatingNewItem because I could not get the automatic stuff to work.Problem is that I can't see a way to get to the parent container row.

Is there some way I can do this?

You can retrieve the row's DataGridContext and the get the parent item through the ParentItem property. If you want the container, then you can call the GetContainerFromItem method to retrieve it.

Does that work on the insertion row as well?

It should. Have you encountered any issues?
