推荐答案

我遇到了同样的事情——它在当前形式下无法正常工作(我希望您在谈论 2010 年 2 月发布的 AutoCompleteBox的 WPFToolkit).

I experienced the same thing -- it does not work properly in its current form (I expect you're talking about the AutoCompleteBox that comes with the February 2010 release of WPFToolkit).

我创建了一个子类:

public class AutoCompleteFocusableBox : AutoCompleteBox
{
    public override void OnApplyTemplate()
    {
        base.OnApplyTemplate();
        var textbox = Template.FindName("Text", this) as TextBox;
        if(textbox != null) textbox.Focus();
    }
}

这会将焦点设置到实际的 TextBox(称为Text")，它是默认 ControlTemplate 的一部分.

This sets focus to the actual TextBox (called "Text") that is part of the default ControlTemplate.
