关闭usercontrol的问题 [英] problem in closing the usercontrol

问题描述

我在WPF中创建一个应用程序，它包含Window和登录UserControl

添加了用户控件作为运行时MainWindow中的子项，现在当我单击usercontrol的登录按钮时，它会登录并加载一个新窗口。但我想关闭登录UserControl而不是父窗口。



i试过这段代码



Window parentWindow = Window.GetWindow（this）;

parentWindow.Close（）;



但它会关闭父窗口而不是用户控件。

请帮助我!!



感谢问候，

没有关闭控件这样的概念。



不仅不需要它，而且并不意味着什么。那是什么意思？您可以1）隐藏控件的实例; 2）永久地从窗口的逻辑树中删除它。

hi,

I am making an application in WPF, which consists of Window and a login UserControl
That user control is added as a child in MainWindow at runtime, now when i click login button of usercontrol it gets logged in and loads a new window. But i want to close the login UserControl alone not the parent window.

i have tried this code

Window parentWindow = Window.GetWindow(this);
parentWindow.Close();

but it closes the parent window not the user control.
Please help me in this!!

Thanks Regards,
Sankar

There is no such concept as "close a control".

Not only it is never needed, but it does not mean anything certain. What is that supposed to mean? You can possibly 1) hide an instance of the control; 2) remove it permanently from the the logical tree of the window.
Please see:

For removing, see, for example:
