The current DataGrid does support grouping.  What it doesn't support is virtualization while grouping.

With Grouping, does the DataGrid allow the adding of a new row?

I appear to be having issues with this.

If I have a DataGrid that is grouping, and is pre-populated with data. 

I then delete the existing rows until there are none left, except the NewRow.

Clicking on the NewRow to add new data throws an exception on line 3450 of the DataGrid.cs

Index was out of range.  Must be non-negative and less than the size of the collection.
Parameter name: index

Hi vinsibal,

Is there any plan to support virtualization while grouping in the future?

Best Regards,

You can't support virtualization with grouping enabled. The two features are incompatible.
