How to make a UserControl remove itself at runtime (in WPF)?
提问by Ali
I have made a userControlconsisting a few labels and checkboxes and an "x" button for removing itself when clicked.
我制作了一个userControl由几个标签和复选框以及一个“x”按钮组成的按钮，用于在单击时自行删除。
Considering that in my WPF application, the user can dynamically put as many of this userControlat runtime as he wants, ANDthat none of them will have a nameattribute to address to, how exactly is it possible to remove a UserControlfrom the application, by clicking on it's -child- button "x" (i.e. inside the event handler of it's "x" button) ???
考虑到在我的 WPF 应用程序中，用户可以根据需要userControl在运行时动态放置尽可能多的这些，并且它们都没有name要寻址的属性，如何UserControl从应用程序中删除 a ，通过单击它是 -child- 按钮“x”（即在它的“x”按钮的事件处理程序中）？？？
I've already looked a thousand places and found these particular two lines of code which DID'NT WORK:
我已经看了一千个地方，发现这两行代码没有用：
((Grid)button.Parent).Children.Remove(this);
((Button)control.Parent).Content = null;

In case your control has been added to any kind of container control (i.e. a class derived from Panel) the following should work:
如果您的控件已添加到任何类型的容器控件（即从 Panel 派生的类），则以下内容应该起作用：
((Panel)this.Parent).Children.Remove(this);
