尝试编辑DataGrid项时出错C＃

Question

So when i try to edit or add or delete from a DataGrid in WPF is giving me 'EditItem' is not allowed for this view.

providersDataGrid.CanUserAddRows = true;
providersDataGrid.CanUserDeleteRows = true;
providersTableAdapter adapter = new providersTableAdapter();
adapter.Fill(ds.providers);
providersDataGrid.ItemsSource = adapter.GetData().Rows;

i have activated Autogenerate Columns.

So how i can do it? thanks for your answer.

Try to set the ItemsSource property to the actual DataView :

providersDataGrid.ItemsSource = ds.providers.DefaultView;

or

providersDataGrid.ItemsSource = adapter.GetData();
