提问by user2631662
How can I navigate to a new page or Windowfrom a page in a desktop WPF application. I have tried the following to call the windows page, but I get the error:
如何导航到新页面或Window从桌面 WPF 应用程序中的页面导航。我尝试了以下方法来调用 windows 页面，但出现错误：
Window must be the root of the tree. Cannot add Window as a child of Visual
窗口必须是树的根。无法将 Window 添加为 Visual 的子项
private void btCode_Click(object sender, RoutedEventArgs e)
{
CodeView window = new CodeView(cbRe.Text, txtID.Text);
this.Content = window;
}
When I alter code to call a new page I get a similar error saying page must be called from a Window.
当我更改代码以调用新页面时，我收到类似的错误消息，指出必须从Window.

As the error states, the Windowelement must be the root element - it cannot be a child of another control. You can opena window from another control, but you cannot make a window the content of another control.
正如错误所述，该Window元素必须是根元素 - 它不能是另一个控件的子元素。您可以从另一个控件打开一个窗口，但不能使一个窗口成为另一个控件的内容。
