一种解决方案是使用带有 a的附加属性Style
来设置InputBindings
应用程序中给定类型的所有控件。不幸的是,由于您无法制作“包罗万象” Style
(无论如何我都知道),因此您必须为Style
要设置的每种控件类型创建一个InputBindings
(但是,这不应该是控件太多)。下面是一些示例代码,展示了如何执行此操作:
using System.Windows;
using System.Windows.Input;
namespace WpfApplication1
{
public class MyAttached
{
public static readonly DependencyProperty InputBindingsProperty =
DependencyProperty.RegisterAttached("InputBindings", typeof(InputBindingCollection), typeof(MyAttached),
new FrameworkPropertyMetadata(new InputBindingCollection(),
(sender, e) =>
{
var element = sender as UIElement;
if (element == null) return;
element.InputBindings.Clear();
element.InputBindings.AddRange((InputBindingCollection)e.NewValue);
}));
public static InputBindingCollection GetInputBindings(UIElement element)
{
return (InputBindingCollection)element.GetValue(InputBindingsProperty);
}
public static void SetInputBindings(UIElement element, InputBindingCollection inputBindings)
{
element.SetValue(InputBindingsProperty, inputBindings);
}
}
}
