Question

I’m trying to do a loading icon where once you tap on the icon, it will call the following handler:

private void refresh_btn_Tap(object sender, System.Windows.Input.GestureEventArgs e)
{
     refresh_btn.Visibility = System.Windows.Visibility.Collapsed;
     loading_icon.Visibility = System.Windows.Visibility.Visible;
     refreshMix();
}

private void refreshMix()
{
    ...
    refresh_btn.Visibility = System.Windows.Visibility.Collapsed;
    loading_icon.Visibility = System.Windows.Visibility.Visible;
}

However, the view doesn’t seem to auto-reload after I change the icon visibilities before calling refreshMix(). Is there a way to force the page to reload itself?

Answer 1

You are probably doing some lengthy work in refreshMix() in UI thread, right? Do this work in background thread and UI thread will be free to update page.
