将ViewModel上的方法附加到WPF中的事件 [英] Attach method on ViewModel to events in WPF

问题描述

如何将WPF控件上的事件绑定到ViewModel上的方法?

How can bind an event on a WPF Control to a method on my ViewModel?

我有一个ViewModel:

I have a ViewModel:

class MyViewModel {
    public string MyText { get; set; }
    public void MyMouseHandleMethod(object sender, EventArgs e) { }
}

在DataTemplate中，我得到了:

In a DataTemplate I've got:

<TextBlock Text="{Binding Text}">

现在，我想将ViewModel上的方法附加到TextBlock上，例如:

Now I would like to attach a method on my ViewModel to the TextBlock, something like:

<TextBlock Text="{Binding MyText}" MouseUp="{Binding MyMouseHandleMethod}">

如果不在后台代码中创建回调，我无法弄清楚该怎么做.

I cannot figure out how to do this without creating a callback in the Code-behind.

Look into using AttachedCommandBehavior from here. It allows you to bind Commands to events entirely in XMAL. Not exactly what you want, but it will give you the same outcome.
