Popup.Opened Event

Occurs when the IsOpen property changes to true.

Namespace: System.Windows.Controls.Primitives
Assembly: PresentationFramework (in presentationframework.dll)
XML Namespace:

public event EventHandler Opened
/** @event */
public void add_Opened (EventHandler value)

/** @event */
public void remove_Opened (EventHandler value)

In JScript, you can handle the events defined by a class, but you cannot define your own.
<object Opened="EventHandler" .../>

A Popup is opened and closed by toggling the IsOpen property.

The following example shows how to define an event handler for the Opened event.

  <Popup Opened="PopupOpening">
    <TextBlock Background="Yellow">Popup Text</TextBlock>

private void PopupOpening(object sender, EventArgs e)
    //Code to execute when Popup opens
