I am making an app in C# that uses Semantic Zoom. I have copied the code from an MS sample called BookStore2Universal_10 and I have made some adjustmens to it. My intention is to click an item in the Zoomed in view. Depending on which item I clicked I want another page to open that downloads and displays a file from the internet. I've succeeded to navigate to this other page but when I navigate back to the zoomed out view and try to click on another item then the program crashes. I don't know how remedy this problem. I'm grateful for any help you can provide. Please let me know if you need more details.
This code acts on the item clicked
private void GridView_ItemClick(object sender, ItemClickEventArgs e)
{
BookSku item = (e.ClickedItem as BookSku);
((Frame)Window.Current.Content).Navigate(typeof(Stations));
}
With the code below I want to get back to the semantic zoom page. But I don't know how I should navigate back. It seems to me that the program tries to initialize again and thereby just crashes no matter which panel name I use instead of the question mark.
private void BackButton_Click(object sender, RoutedEventArgs e)
{
((Frame)Window.Current.Content).Navigate(typeof(?));
}
I expect to get back to the zoomed out panel, which I do, and continue selecting another item. But instead this error message appears:
An unhandled win32 exception occurred in BookStore2Universal_10.exe [4020]
