Two way Binding

Question

I have some code and I'm having problems trying to change the value of the class 'Player'

My XAML

<Rectangle x:Name="oChar" Fill="Orange" Height="32" Width="32" Canvas.Left="32" Canvas.Top="{Binding Mode=TwoWay}"/>

Code behind:

    private Player myPlayer = new Player { left = 32, top = 128 };
    public MainPage()
    {
        this.InitializeComponent();

        this.DataContext = myPlayer.top;
        myPlayer.top += 32;
    }

Class INotiftyProperty

    private int _top;

    public int top
    {

        get { return _top; }

        set { _top = value; OnPropertyChanged("top"); }

    }


    public event PropertyChangedEventHandler PropertyChanged;

    protected void OnPropertyChanged(string propertyName)
    {
        if (PropertyChanged != null)
        {
            PropertyChanged(this, new PropertyChangedEventArgs(propertyName));
        }
    }

First time doing stuff like WPF, any help on why the value wont change or any information would be great!

Answer 1

You should use this.Datacontext =myPlayer;
