Implementing master-detail in the DataGrid

In order to save screen space, not creating too many columns in a DataGrid may be a good idea. A better solution in this case is to create a master-detail implementation. The master, being the original row in the DataGrid, would then contain a few columns only. When clicking on any row, the details of that row are shown. In the Silverlight DataGrid, this is possible due to the RowDetailsTemplate.
