如何将事件鼠标附加到具有依赖项属性的元素 [英] How can attach a event mouse down to element which have dependency property

问题描述

大家好，



我想问你一路将事件附加到具有依赖属性的元素。

我确实没有效果。



1.注册表帮助ID

Hi Guys,

I would like to ask you all the way to attach event to element which has dependency property.
I did but got no effect.

1. registry help ID

public static readonly DependencyProperty HelpIDProperty =
    DependencyProperty.RegisterAttached("HelpID", typeof(string), typeof(HelpProvider));

2 。将helpID设置为元素时附加事件

2. Attach event when setting helpID to element

public static void SetHelpID(DependencyObject obj, string value)
{

    obj.SetValue(HelpIDProperty, value);
    var element = obj as FrameworkElement;
    if (element != null)
    {
        element.MouseDown += SensitiveElementOnMouseDown;
    }
}
