Walkthrough: Hosting a Windows Forms Control in WPF by Using XAML

WPF provides many controls with a rich feature set. However, you may sometimes want to use Windows Forms controls on your WPF pages. For example, you may have a substantial investment in existing Windows Forms controls, or you may have a Windows Forms control that provides unique functionality.

This walkthrough shows you how to host a Windows Forms xref:System.Windows.Forms.MaskedTextBox?displayProperty=nameWithType control on a WPF page by using XAML.

For a complete code listing of the tasks shown in this walkthrough, see Hosting a Windows Forms Control in WPF by Using XAML Sample.

Prerequisites

You need Visual Studio to complete this walkthrough.

Hosting the Windows Forms Control

To host the MaskedTextBox control

1. Create a WPF Application project named HostingWfInWpfWithXaml.

2. Add references to the following assemblies.

   • WindowsFormsIntegration

   • System.Windows.Forms

3. Open MainWindow.xaml in the WPF Designer.

4. In the xref:System.Windows.Window element, add the following namespace mapping. The wf namespace mapping establishes a reference to the assembly that contains the Windows Forms control.

   xmlns:wf="clr-namespace:System.Windows.Forms;assembly=System.Windows.Forms"  
   

5. In the xref:System.Windows.Controls.Grid element add the following XAML.

   The xref:System.Windows.Forms.MaskedTextBox control is created as a child of the xref:System.Windows.Forms.Integration.WindowsFormsHost control.
