ChildWindow.Closed Event

Occurs when the ChildWindow is closed.

Namespace:  System.Windows.Controls
Assembly:  System.Windows.Controls (in System.Windows.Controls.dll)

public event EventHandler Closed
<sdk:ChildWindow Closed="eventHandler"/>

To access the property values of a child window, handle the Closed event in the code-behind page of the calling window. In the Closed event handler cast the sender parameter to a ChildWindow or a derived class to access the child window properties.

The following example demonstrates how to handle the Closed event in the code-behind page of the parent window. The LoginWindow class is derived from ChildWindow. In the button click event handler, the LoginWindow is instantiated and a handler for the Closed event is attached. In the Closed event handler, the sender parameter is cast to a LoginWindow. It is then used to access the DialogResult property and the Name text box. This example is part of a larger example available in the ChildWindow class overview.

private void Button_Click(object sender, RoutedEventArgs e)
    LoginWindow loginWnd = new LoginWindow();
    loginWnd.Closed += new EventHandler(loginWnd_Closed);
void loginWnd_Closed(object sender, EventArgs e)
    LoginWindow lw = (LoginWindow)sender;

    if (lw.DialogResult == true && lw.nameBox.Text != string.Empty)
        this.helloTxt.Text = "Hello " + lw.nameBox.Text;
    else if (lw.DialogResult == false)
        this.helloTxt.Text = "Login canceled.";
