Datagrid, Merge/Combine rows, cells and columns

Question

I'm trying to acomplish exactly what this question is requesting, but unfortunately the code sample that was provided as the answer is gone, and I'm also not using WPF Toolkit, here the question that he did:

I am trying to Merge cells in WPF toolkit datagrid .I am trying to do something as shown in the image below.We can do this in Winforms datagrid.But how to do this using WPF toolkit datagrid ?.Or is there any alternative controls..?

Can we do this using listview or listbox..? Or is there any free controls available which have this functionality ?

I found several answers that manage to do this with the DataGridView control, but I do not want to use Form objects in a WPF project, is there a way to acomplish this?
