在WPF中添加上下文菜单

I have a WPF user control. In that userControl I'll have multmple WPF childControls(inherits MyBaseElement).

我有一个WPF用户控件。在那个userControl中,我将拥有多个WPF childControls(继承MyBaseElement)。

I need that every ChildControl contains a specified context menu (backward, forward commands)

我需要每个ChildControl都包含一个指定的上下文菜单(向后,向前命令)

The code bellow does not work... What I do wrong?

下面的代码不起作用......我做错了什么?

<UserControl.Resources>
    <ContextMenu x:Key="ElementContextMenu">
        <MenuItem Header="Move backward"
                  Name="back"
                  Click="back_Click" />
        <MenuItem Header="Move forward"
                  Name="forw"
                  Click="forw_Click" />
    </ContextMenu>
    <Style TargetType="{x:Type my:BaseElement}">
        <Setter Property="ContextMenu"
                Value="{DynamicResource ResourceKey=ElementContextMenu}" />

A base style isn't applied automatically to derived elements, you need to create a style for each one. Fortunately you can use style inheritance through the BasedOn property.

基本样式不会自动应用于派生元素,您需要为每个元素创建样式。幸运的是,您可以通过BasedOn属性使用样式继承。

<UserControl.Resources>
  <Style
    TargetType="{x:Type my:Element1DerivingFromBase}"
    BasedOn="{StaticResource {x:Type my:BaseElement}}" />

  <Style
    TargetType="{x:Type my:Element2DerivingFromBase}"
    BasedOn="{StaticResource {x:Type my:BaseElement}}" />
