XAMGrid using PersistanceManager save colums when new column is added
posted

I am saving the columns of a XAMGrid using the persistance manager.  If I add a new column to the grid and then load the settings back in, the new columns are no longer there and cannot be shown.

    HI Edwin,

     You could wire up the PersistenceSettings' Objects' Loaded Event. In that event you could add the new columns.

     Here is a code snippet:
     

    ObservableCollection<Person> people = new ObservableCollection<Person>();    

         PersistenceGroup _SettingsGroup;

           PersistenceSettings settings;

             string fileName = "TEST";  

                 public MainPage()      

       {    

             InitializeComponent();  

               _SettingsGroup = (PersistenceGroup) LayoutRoot.Resources["SETTINGS"] as PersistenceGroup;

                settings = (PersistenceSettings)LayoutRoot.Resources["ColumnSettings"] as PersistenceSettings;     

            settings.Events.PersistenceSaved += new EventHandler<PersistenceSavedEventArgs>(Events_PersistenceSaved);

                settings.Events.PersistenceLoaded += new EventHandler<PersistenceLoadedEventArgs>(Events_PersistenceLoaded);

            }

            void Events_PersistenceLoaded(object sender, PersistenceLoadedEventArgs e)

            {  

               //throw new NotImplementedException();

                 foreach (Column c in xgrid1.Columns)  

               {

                     int i = int.Parse(c.Tag.ToString());

                      xgrid1.Columns.Remove(c);

                    xgrid1.Columns.Insert(i, c);

                }

            }

     Sincerely,
