How to: Copy and paste an ElementHost control

This procedure shows you how to copy a Windows Presentation Foundation (WPF) control on a Windows Form in Visual Studio.

1. In Visual Studio, add a new WPF xref:System.Windows.Controls.UserControl to a Windows Forms project. Use the default name for the control type, UserControl1.xaml. For more information, see Walkthrough: Creating New WPF Content on Windows Forms at Design Time.

2. In the Properties window, set the value of the xref:System.Windows.FrameworkElement.Width%2A and xref:System.Windows.FrameworkElement.Height%2A properties of UserControl1 to 200.

3. Set the value of the xref:System.Windows.Controls.Control.Background%2A property to Blue.

4. Build the project.

5. Open Form1 in the Windows Forms Designer.

6. From the Toolbox, drag an instance of UserControl1 onto the form.

   An instance of UserControl1 is hosted in a new xref:System.Windows.Forms.Integration.ElementHost control named elementHost1.

7. With elementHost1 selected, press Ctrl+C to copy it to the clipboard.

8. Press Ctrl+V to paste the copied control onto the form.

   A new xref:System.Windows.Forms.Integration.ElementHost control named elementHost2 is created on the form.
