如何从嵌套UserControl调用另一个UserControl [英] How to call from Nested UserControl another UserControl

问题描述

Hello Everyone



我正在努力解决我的嵌套UserControl问题。



当我运行应用程序时，主窗口打开，主窗口内有一个按钮，当我点击该按钮时，它会调用一个UserControl（称为Applic）。



里面Applic UserControl是另一个名为PasswordScreen的嵌套UserControl。



在PasswordScreen中有一个名为Login的按钮，当我按下此按钮调用另一个UserControl（称为SwitchboardView）时什么都没招（这里是示例代码）

<前lang =c＃> 私人 < span class =code-keyword> void btnLogin_Click（ object sender，RoutedEventArgs e）
{
Applic ap = new Applic（）;
SwitchboardView sbv = new SwitchboardView（）;

ap.MainGridApplic.Children.Add（sbv）;

}

有人可以帮我解决这个问题，我一直在苦苦挣扎解决这个问题，但我无法解决这个问题。



提前致谢...



亲切的问候

使用冒泡事件。因此事件在主窗口中处理。

Hello Everyone

I'm struggling to solve the problem with my nested UserControl.

When I run the application the main window opens, inside the main window is a button, when I click that button it calls up a UserControl (called Applic).

Inside the Applic UserControl is another nested UserControl called PasswordScreen.

Within the PasswordScreen there is a button called Login, when I press this button to call another UserControl (called SwitchboardView) it is not firing nothing (here is the sample code)

private void btnLogin_Click(object sender, RoutedEventArgs e)
        {
            Applic ap = new Applic();
            SwitchboardView sbv = new SwitchboardView();
            
            ap.MainGridApplic.Children.Add(sbv);

        }

Could someone please help me solve this problem, I have been struggling for a long time to solve this problem but I just can't get it around.

Thanks in advance...

Kind regards

Hi,

Use the bubbling event.So that the events are handled in the main window.
