gistfile1.txt

listView.ItemSelected += async (object sender, SelectedItemChangedEventArgs e) => {
        
//Paste this ---v        
        // Prevents .ItemSelected from running again when SelectedItem is set to null on line below
        if (listView.SelectedItem == null)
                return;
		
	// Sets the SelectedItem so it can be used by the Switch statement below
	var whichCategory = (Category)e.SelectedItem;
 
	// Clears the SelectedItem, this will trigger a 2nd .ItemSelected event which is caught on line above
        listView.SelectedItem = null;
 
        //Console.WriteLine("Clicked"); //just for testing when the .ItemSelected event is being triggered
//Paste this--^
	
		
	switch (whichCategory.Name.ToString())
	{
	case "item 1":
        	Navigation.PushAsync(new SomePage());
		break;
	case "item 2":
                Navigation.PushAsync(new SomePage());
		break;
