public partial class ServerViewModel : ITitleBarAutoSuggestBoxAware
{
    public void OnAutoSuggestBoxTextChanged(AutoSuggestBox sender, AutoSuggestBoxTextChangedEventArgs args)
    {
        Search(sender.Text);
    }

    public void OnAutoSuggestBoxQuerySubmitted(AutoSuggestBox sender, AutoSuggestBoxQuerySubmittedEventArgs args)
    {
        Search(sender.Text);
