Last row in WPF datagrid binded to a different collection

I have an ObservableCollection A binded to a DataGrid in WPF. The user can add, remove and edit rows and this work fine.

I would like to add an 'additional row' in the end of a DataGrid, serving as a 'summary' for a given column. This row would be binded to a completly other collection B. We can assume that number of columns in DataGrid is equal to number of elements in B.

It doesn't have to be one control - I would like to make it LOOK LIKE one. Especially, when user resizes columns, the "last row" resizes accordingly.开发者_如何学JAVA Secondly, this row is always in the very end.

Any ideas how to achieve such a thing? Thanks!

One solution would be to use a MultiBinding.
