You could find the WpfPageTransitions.PageTransition control like this from the UserControls code behind:
您可以从后面的 UserControls 代码中找到这样的 WpfPageTransitions.PageTransition 控件：
public static WpfPageTransitions.PageTransition FindPageControl(DependencyObject child)
{
DependencyObject parent= VisualTreeHelper.GetParent(child);
if (parent == null) return null;
WpfPageTransitions.PageTransition page = parent as WpfPageTransitions.PageTransition;
if (page != null)
{
return page;
}
else
{
return FindPageControl(parent);
}
}
Then you can use it like this:
然后你可以像这样使用它：
this.FindPageControl(this).ShowPage(...);

Create A Method Inside Main Window for Choosing Page Transition
在主窗口内创建用于选择页面过渡的方法
public void ChangePage()
{
pageTransitionControl.ShowPage(new NewData());
}
Then in Child control
然后在儿童控制
private void btnUpdate_Click(object sender,RoutedEventArgs e)
{
MainWindow win = (MainWindow)Window.GetWindow(this);
win.ChangePage();
}
