I would like to display a WPF window from a windows forms application (.NET 3.5).
This code seems to work without any problem in a sample project:
public partial class WinFormsForm1 : Form
{
public WinFormsForm1() {
InitializeComponent();
}
private void button1_Click(object sender, EventArgs e) {
WpfWindow1 w = new WpfWindow1();
w.Show();
}
}
The form is started from Main()
as a normal Winforms form:
Application.Run(new WinFormsForm1());
This seems to me too easy to be true. Are there any shortcomings in this? Is this safe to do?
It has one serious shortcoming: the modeless WPF window would not get keyboard input.
The EnableModelessKeyboardInterop
method call needs to be added before the WPF window is shown:
WpfWindow1 w = new WpfWindow1();
System.Windows.Forms.Integration.ElementHost.EnableModelessKeyboardInterop(w);
w.Show();
ElementHost resides in WindowsFormsIntegration.dll.
