Hi Jay_P85,

GridView.ScrollIntoView method helps you move scrollbar to special object in GridView. Use OnNavigatedFrom event handler to remember the scrollview position, save it in LocalSettings. In OnNavigatedTo event handler, use ScrollIntoView method with position object in LocalSettings.

I am not familiar with VB.NET, hope the following code snippet can help you.

Protected Overrides Sub OnNavigatedTo(e As NavigationEventArgs)

        Dim t As Item = DirectCast(ApplicationData.Current.LocalSettings.Values("scroll"), Item)

        FlavorGrid.ScrollIntoView(t)

    End Sub


    Protected Overrides Sub OnNavigatedFrom(e As NavigationEventArgs)

        Dim t As Item = DirectCast(storeData.Collection.LastOrDefault(), Item)

        ApplicationData.Current.LocalSettings.Values.Clear()

        ApplicationData.Current.LocalSettings.Values.Add("scroll", scrollItem)

End Sub
