Pass values between windows

shers

Hello,

In WPF, I open window2 from window1 with a button click keeping window1 open. When I close window2, I want to display 2 values in window1. How can this be achieved?

Thanks

Assuming the values you want to show are contained in Window2. You need to register a method to the "Closed" event of Window2. Like this;

private void StartWindow()
{
Window window2 = new Window();
window2.Closed += new EventHandler(window2_Closed);
window2.Show();
}
void window2_Closed(object sender, EventArgs e)
{
Window window2 = sender as Window;
if (window2 != null)
{
//display message
MessageBox.Show(window2.Text1);
MessageBox.Show(window2.Text2);
}
}

Try it with DataBinding. Just bind the Controls in Window1 and Window2 on the properties of the same object.

class Data : INotifyPropertyChanged
{
private int myVar;

    public int MyProperty
    {
        get { return myVar; }
        set 
        { myVar = value;
        this.OnPropertyChanged("MyProperty");
        }
    }




    #region PropertyChangedEvent
    public event PropertyChangedEventHandler PropertyChanged;

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

    #endregion

}

And e.g.

Data d = new Data();
Window1.DataContext = d;
Window2.DataContext = d;

In Windows2.xaml

e.g. In Windows1.xaml
