我在Windows中有一个键盘焦点问题窗体应用程序承载WPF用户控件。当我按Tab键时,如果UserControl中只有WPF控件,导航工作正常。如果我将WindowsFormsHost托管控件添加到此WPF UserControl,则焦点不会从WPF UserControl中的WindowsFormsHosted控件移开。键盘焦点导航问题托管WPF查看与WindowsFormsHost主办控制
当应用程序是WPF应用程序,重点导航完美的作品,但是当我添加此WPF用户控件到Windows窗体应用程序,按下TAB键不起作用了。
这将是巨大的,得到一些帮助与此有关。
这里是我的代码:
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
ElementHost host = new ElementHost();
host.Dock = DockStyle.Fill;
host.Child = new SomeControls();
this.Controls.Add(host);
}
}
/// <summary>
/// Interaction logic for SomeControls.xaml
/// </summary>
public partial class SomeControls : UserControl
{
public SomeControls()
{
InitializeComponent();
}
}
<UserControl x:Class="TabAndHostTest.SomeControls"

谢谢您的回答。这里有很好的链接。其中一些链接我已经检查过,但我无法弄清楚为什么在应用程序是WPF应用程序时,焦点不会从托管文本框中传出。 http://www.codeproject.com/KB/WPF/EnhancedFocusScope.aspx: – Trainee 2011-05-31 09:43:30
