            </LinearGradientBrush>
        </DataGrid.Resources>
        <DataGrid.Columns>
            <DataGridTextColumn Width="30" Header="Id" IsReadOnly="True" Binding="{Binding Id}"/>

Exceptions

Exception:Thrown: "'EditItem' is not allowed for this view."(System.InvalidOperationException)

You should use an ObservableCollection<DataClients>() as source for your Datagrid and not add the items directly to your DataGrid . To do this, you create a property ObservableCollection<DataClients> Data and use it as the ItemsSource in your DataGrid like this ItemsSource="{Binding MyBikesOrders}" . You can then add the items to the ObservableCollection , update the DataGrid and you should be able to edit the entries directly in it.

Here 'sa very similar question to yours.
