I have two SfDataGrids in one window. By clicking on row in one dataGrid -> item goes to second SfdataGrid with Master-Details view and automatically grouping. My problem is following: i create ContextMenu separately in MasterRow and Details Row, and if i deleting Master-Row (with all underlying details-rows), its Ok, all rows deleted and SfDataGrid updates, but if i am want to delete row in Details-Rows, there are problem with SfDataGrid view updating. When i delete details row, SfdataGrid dont updating and all rows still visible (but some of them alredy deleted from details collections in viewmodel). I try to use SfdataGrid.View.Refresh(),SfDataGrid.UpdateDataRow but view still dont updating. Where is my mistake? Can you help me with that problem?
