将事件设置为所有相同类型的控件 [英] Set an event to all controls of same type

问题描述

在WPF中，有一种方法可以为特定类型的所有控件设置特定类型的事件。例如，我试图在所有TextBlock类型的控件上设置MouseLeftButtonDown事件。这是我尝试做的事情，这显然是错误的：

In WPF is there a way to set a particular type of event to all controls of the same type. For example, I'm trying to set the MouseLeftButtonDown event on all controls of type TextBlock. Here is what I tried to do which is obviously wrong:

<Style TargetType="{x:Type TextBlock}">
    <Setter Property="MouseLeftButtonDown" Value="TextBlock_LeftClick"/>
</Style>

有没有办法做到这一点？

Is there a way that this can be done?

推荐答案

是的，有一种方法，您可以在 Style 中使用 EventSetter 属性为所有应用了该样式的 Elements 设置一个 EventHandler

Yes there is a way, you can use the EventSetter property in the Style to set a EventHandler for all Elements with that style applied

示例：

<Style TargetType="{x:Type TextBlock}">
    <EventSetter Event="MouseLeftButtonDown" Handler="TextBlock_LeftClick" />
</Style>
