I have created an On-screen-Keyboard as a WPF user control.
This WPF user control works fine (whenever i press a button,the text goes to the focused element) when used in a WPF application.

But when i use this WPF usercontrol in a Winform application using elementhost.child, the text doesnot go to any focused element in winform.

How do i route the OSk text content[when i press any key..i.e. button] to any focused element [eg: textbox] in winform?

Hi,

Sorry. Unfortunately, I am not able to reproduce this issue.

I drag a button and a textbox on the wpf UserControl:

namespace WpfControlLibrary1

{

/// <summary>

/// Interaction logic for UserControl1.xaml

/// </summary>

public partial class UserControl1 : UserControl

{

public UserControl1()

{

InitializeComponent();

}

private void button1_Click(object sender, RoutedEventArgs e)

{

textBox1.Text += "1";

textBox1.Focus();

}

}

}

In the winform application.

private void Form1_Load(object sender, EventArgs e)

{

ElementHost host = new ElementHost();

host.Dock = DockStyle.Fill;

WpfControlLibrary1.UserControl1 uc = new WpfControlLibrary1.UserControl1();

host.Child = uc;

this.Controls.Add(host);

}

When I click the button, the textbox show ��and get focus.

I think I must miss something. Could you please provide more details or make a demo project for us to test? Please upload your demo project to some server and offer us the URL. Skydrive (http://skydrive.live.com/ ) may be a good option. You can sign up 25GB free space only with your Windows Live Passport.
