I am writing an application which contains two pages, GroupedItemsPage and ItemDetailPage. I let lots of pictures present in the GroupItemsPage, then after select a specified picture in this page, it will nevigate the the second page withe the details showing for the selected picture. Since I put too much pictures in the first page, therefore the gridview always put the top picutres into view each time I goback to the first page. even the picture I selected previously are the last picture which need a scroll to the end.

 

I tried to use GridView.ScrollIntoView() in the LoadState method, my codes like below.

protected override void LoadState(Object navigationParameter, Dictionary
     
       pageState)        {            // TODO: Create an appropriate data model for your problem domain to replace the sample data            var sampleDataGroups = SampleDataSource.GetGroups((String)navigationParameter);            this.DefaultViewModel["Groups"] = sampleDataGroups;            if (pageState!=null&&pageState.ContainsKey("SelectedItem"))            {                SelectedItemId = pageState["SelectedItem"].ToString ();                var sampleDataItem = SampleDataSource.GetItem(SelectedItemId);                //SampleDataGroup group = ((SampleDataItem)sampleDataItem).Group;                //groupedItemsViewSource.View.MoveCurrentTo(group);                itemGridView.ScrollIntoView(sampleDataItem);               }        }
     

however, nomatter what I do, it just doesn't work.

 

then I moved the method call to Loaded event like below. It works:

public GroupedItemsPage()        {            this.InitializeComponent();            Loaded += GroupedItemsPage_Loaded;        }        void GroupedItemsPage_Loaded(object sender, RoutedEventArgs e)        {            if (SelectedItemId!=null&&SelectedItemId != string.Empty)            {                var sampleDataItem = SampleDataSource.GetItem(SelectedItemId);                //SampleDataGroup group = ((SampleDataItem)sampleDataItem).Group;                //groupedItemsViewSource.View.MoveCurrentTo(group);                itemGridView.ScrollIntoView(sampleDataItem);                }        }
