我有一个 wpf 应用程序,我想将所有内容设置为 Focusable="false"。有没有简单优雅的方法?目前我为我使用的每种类型的控件制作了一个样式,如下所示:

<Style TargetType="Button">
<Setter Property="Focusable" Value="False"></Setter>
</Style>

对更通用的解决方案有任何想法吗?

为什么不尝试两行解决方案?

 foreach (var ctrl in myWindow.GetChildren())
{
//Add codes here :)
}  

还要确保添加这个:

  public static IEnumerable<Visual> GetChildren(this Visual parent, bool recurse = true)
 {
if (parent != null)
{
    int count = VisualTreeHelper.GetChildrenCount(parent);
    for (int i = 0; i < count; i++)
    {
        // Retrieve child visual at specified index value.
        var child = VisualTreeHelper.GetChild(parent, i) as Visual;

        if (child != null)
        {
            yield return child;

            if (recurse)
            {
                foreach (var grandChild in child.GetChildren(true))
                {
                    yield return grandChild;
                }
            }
        }
    }
}
}

甚至更短,使用这个:

public static IList<Control> GetControls(this DependencyObject parent)
{            
    var result = new List<Control>();
    for (int x = 0; x < VisualTreeHelper.GetChildrenCount(parent); x++)
    {
        DependencyObject child = VisualTreeHelper.GetChild(parent, x);
        var instance = child as Control;

        if (null != instance)
            result.Add(instance);

        result.AddRange(child.GetControls());
    } 
    return result;
}
