Right now I have a WPF DataGrid that displays a list obtained from a LINQ to Entity query. That however does not mean that if I delete something from my data base, it’ll be removed immediately from the DataGrid. I tried myGrid.Items.Refresh(), but it refreshed only one cell.
I know the ObservableCollection could somehow solve the problem but I don’t know where to create such collection and proper methods so that whenever I create/add/modify database, the collections gets modified too.
The DataGrid has the data from the time the query was run.
If you want fresh data you need to rerun the query.
