    Windows forms Integration in WPF

    Hosting Windows form control in WPF:

    Windows Forms to WPF Interop is one of the features of wpf, where the controls existing in winforms can be used in WPF.This is achieved using the windowsformshost.

    Namespace: System.Windows.Forms.Integration
    Assembly: WindowsFormsIntegration
    Below is the sample where a windows forms datatimepicker is used in WPF.


    1. Create a WPF project HostWindowsControl.

    2. Add the following references to the project

    3. Open the MainWindow.xaml file in designer.

    4. Add the window load event

     <Window x:Class="HostWindowsControl.MainWindow"
            Title="MainWindow" Height="350" Width="525" Loaded="Window_Loaded">
         <Grid Name="Host">

    5. Open the MainWindow.cs.xaml file, add the following reference.

    using System.Windows.Forms;

    6. In the window load event add the following code.

         private void Window_Loaded(object sender, RoutedEventArgs e)
                // Createing the interop host control object.
                System.Windows.Forms.Integration.WindowsFormsHost hostobject =
                    new System.Windows.Forms.Integration.WindowsFormsHost();
                // Create the DateTimePicker control object.
                DateTimePicker DtTime = new DateTimePicker();
                // set DateTimePicker control as the hostobject child.
                hostobject.Child = DtTime;
                // Adding the windows interop host control to the Grid

    7. Now run the application.You will see the DateTimePicker control in the wpf form.
