Im "porting" a Win app to WPF, and with "Infragistics.Win.UltraWinGrid" I could easily mov a row bay drag and drop inside one grid

I used in the "SelectionDrag" event:  ultraGridMediaLib.DoDragDrop(this.ultraGridMediaLib.Selected.Rows, DragDropEffects.Move);

 How do I do this by C# code in WPF XamDataGrid.

Thanks!
