如何在usercontrol中创建一个事件并将其置于主窗体中 [英] How do I make an event in the usercontrol and have it handeled in the main form

问题描述

我在wpf中有一个应用程序，我使用UserControl来填充一些数据。我需要在父窗口中执行一些操作，同时单击UserControl中的按钮。

我尝试使用事件和代理但是无法在父窗口中调用该功能。



我尝试过：



在我的usercontrol中我有这样的代码

I have an application in wpf where I use UserControl to fill some data.I need some actions performed in the parent window while clicking on a button in UserControl.
I tried using events and delegates but failed to call the function in parent window.

What I have tried:

in my usercontrol I have code like this

// A delegate type for hooking up change notifications.
    public delegate void Button_ClickedEventHandler(object sender, EventArgs e);

..........

。 ........

..........
.........

// An event that clients can use to be notified whenever the
       // the button is clicked
       public event Button_ClickedEventHandler ButtonClicked;

................

....... .........

................
................

// Invoke the event; called whenever button clicked
public void button1_Click(object sender, RoutedEventArgs e)
       {

              if (this.ButtonClicked != null)
               this.ButtonClicked(this,e);
       }

.......................... ................

和父窗口

..........................................
and in the parent window

public myWindow()
       {
           InitializeComponent();
           myClass1.ButtonClicked += new Button_ClickedEventHandler(myClass1_ButtonClicked);

       }

void myClass1_ButtonClicked(object sender, EventArgs e)
       {
           throw new NotImplementedException();
       }

只需添加一个事件，然后获取容器表单来处理它：添加事件的简单代码段 [ ^ ] - 它显示了您需要的代码，以及如何在VS中自动化。
