如何在同一窗口中打开新的XAML页 [英] How to open a new XAML page in the same window

问题描述

我有两个XAML页面，当您单击其中一个按钮时，将打开另一个页面.我的代码是:

I have two XAML pages and when you click a button in one, the other page opens. My code is:

private void cookingButton(object sender, RoutedEventArgs e)
{
    CookingMenu cooking = new CookingMenu();
    cooking.Show();
}

CookingMenu是XAML页面的名称.此代码在新窗口中打开页面，但是有没有办法在同一窗口中打开页面?这两页的尺寸相同.

CookingMenu is the name of the XAML page. This code opens the page in a new window but is there any way to open the page in the same window? Both the pages are the same size.
