Question

我在运行时生成了几个包含内部东西的Border元素。我设法产生它们但现在我想将事件与MouseEnter，Click等相关联，但我不知道如何。我设法将每个Border元素与一个唯一的名称（Name属性）相关联，因此如果我需要，我可以使用它们。如何在C＃？

中为每个生成的Border元素添加事件

Answer 1

像这样使用

 border.MouseEnter += new MouseEventHandler(border_MouseEnter);

void border_MouseEnter(object sender, MouseEventArgs e)
 {
   throw new NotImplementedException();
 }

Answer 2

 <Style x:Key="BorderNameStyle" TargetType="{x:Type BorderName}">
                <EventSetter Event="MouseEnter" Handler="itm_MouseEnter"></EventSetter>
                <EventSetter Event="MouseLeftButtonUp" Handler="itm_MouseLeftButtonUp"></EventSetter>
                <EventSetter Event="PreviewMouseRightButtonUp" Handler="itm_MouseRightButtonUp"></EventSetter>
                <EventSetter Event="MouseLeave"  Handler="itm_MouseLeave"></EventSetter>
                <EventSetter Event="MouseDoubleClick" Handler="ItemMouseDoubleClick"></EventSetter>
</Style>

通过为Border或代码定义样式，您需要调用如下的路由事件。

    border.MouseEnter += new MouseEventHandler(border_MouseEnter);

    void border_MouseEnter(object sender, MouseEventArgs e)
     {
        Button btn = new Button();
        btn.Click += new RoutedEventHandler(btn_Click);
     }
    void btn_Click(object sender, RoutedEventArgs e)
    {
        throw new NotImplementedException();
    }
