Windows Phone 8 threading Invalid cross-thread access

Question

private Button[] bts;
private List<         


        

Answer 1

You cannot access the UI thread from any other thread directly. So, Encose your UI access code in the Dispatcher.BeginInvoke()

Dispatcher.BeginInvoke(() =>
    {
        foreach (Button i in bts)
           i.Content = "";
    });
