如何将silverlight表单中的回车键更改为tab键。我在winforms中使用了以下代码，但我不知道如何在silverlight中实现这一点！

/// <summary>
/// Change Enter key To Tab Key
/// </summary>
/// <param name="msg"></param>
/// <param name="keyData"></param>
/// <returns></returns>
protected override bool ProcessCmdKey(ref Message msg, Keys keyData)
{
    if (msg.Msg == 256 && keyData == Keys.Enter)
    {
        // Execute an alternative action: here we tabulate in order to focus on the next control in the formular             
        if (ActiveControl.ToString().Contains("System.Windows.Forms.Button") ||
            ActiveControl.ToString().Contains("DevComponents.DotNetBar.ButtonX"))
            return base.ProcessCmdKey(ref msg, keyData);
        SendKeys.Send("{TAB}");
        // return true to stop any further interpretation of this key action
        return true;
    }
    return base.ProcessCmdKey(ref msg, keyData);
}

将输入键更改为银色窗体中的Tab键

有点晚了，但任何人都可以查看此线程-在Silverlight 5中使用AutomationFactory按ENTER键时可以使用TAB键。我通过编写一个行为来做到这一点，在该行为中，您可以收听KeyDown并传入TAB键。应用程序必须在OOB模式下运行。您可以将此行为附加到Blend中的文本框中。

public class EnterKeyPropertyChangeBehaviour : Behavior<DependencyObject>
{
    public EnterKeyPropertyChangeBehaviour()
    {
    }
    protected override void OnAttached()
    {
        base.OnAttached();
        // Insert code that you would want run when the Behavior is attached to an object.
        var fe = AssociatedObject as FrameworkElement;
        if (fe != null) fe.KeyDown += fe_KeyDown;
    }
    void fe_KeyDown(object sender, KeyEventArgs e)
    {
        if (e.Key == Key.Enter)
        {
            using (dynamic shell = AutomationFactory.CreateObject("WScript.Shell"))
            {
                shell.SendKeys("{TAB}");
            }   
        }
    }
    protected override void OnDetaching()
    {
        base.OnDetaching();
        // Insert code that you would want run when the Behavior is removed from an object.
        var fe = AssociatedObject as FrameworkElement;
        if (fe != null) fe.KeyDown -= fe_KeyDown;
    }
}

在Silverlight中，我们有KeyDown事件，可以检查按下了哪个键。您可以在KeyDown事件和该检查中编写一个函数。如果e.key==Enter键按下，则将焦点集中到您想要的Desired TextBox。
