  •  No i do'nt want  group format. It should be editable at all levels.

  • What I feel is you can add and remove rows based on expand collase images click events which you can place in the first column of the Datagrid. Keep one global list which will have the complete list and then you can have a copy of that list from where you can add and remove rows.

  •  You can set <RowDetailsTemplate/> to display the child data. You can have nested DataGrid in the Detail section.

  • Using <RowDetailsTemplate/> wont solve my problem. Is there any other solution

  • I think you forgot to add Extensions.cs file in your Project. Check that.
