How to navigate to other Pages in Grid App (XAML) Template in Windows Store Apps?

If the project is created using Grid App template, the page that gets loaded is "GroupedItemsPage". In order to change the navigation page on item click, go to the click event of the item in code-behind file...it could be something like this

C#

void ItemView_ItemClick(object sender, ItemClickEventArgs e)
        {
            // Navigate to the appropriate destination page, configuring the new page
            // by passing required information as a navigation parameter
            var itemId = ((SampleDataItem)e.ClickedItem).UniqueId;
            this.Frame.Navigate(typeof(ItemDetailPage), itemId);
        }

so here you can change the page you need and pass required params

this.Frame.Navigate(typeof(YourNewPage));

VB:

Private Sub ItemView_ItemClick(sender As Object, e As ItemClickEventArgs)

       ' Navigate to the appropriate destination page, configuring the new page
       ' by passing required information as a navigation parameter
       Dim itemId As String = DirectCast(e.ClickedItem, Data.SampleDataItem).UniqueId
       Me.Frame.Navigate(GetType(ItemDetailPage), itemId)
   End Sub

so here you can change the page you need and pass required params

Me.Frame.Navigate(GetType(YourNewPage))
