Property Value

The hosted Windows Forms control.
Exception typeCondition

ArgumentException

An attempt was made to assign a top-level form as the hosted control.

Only one child control can be hosted, but Child can have any number of children.

The child control cannot be a top-level form.

If Child is a Form, the form's ControlBox property is set to false.

The following code example demonstrates how to use the Child property to add the hosted control to the WindowsFormsHost element. For more information, see Walkthrough: Hosting an ActiveX Control in Windows Presentation Foundation.

private void WindowLoaded(object sender, RoutedEventArgs e) 
{
    // Create the interop host control.
    System.Windows.Forms.Integration.WindowsFormsHost host =
        new System.Windows.Forms.Integration.WindowsFormsHost();

    // Create the ActiveX control.
    AxWMPLib.AxWindowsMediaPlayer axWmp = new AxWMPLib.AxWindowsMediaPlayer();

    // Assign the ActiveX control as the host control's child.
    host.Child = axWmp;

    // Add the interop host control to the Grid
    // control's collection of child controls.
    this.grid1.Children.Add(host);

    // Play a .wav file with the ActiveX control.
    axWmp.URL = @"C:\WINDOWS\Media\Windows XP Startup.wav";
}
