In Win UI 3 how can I change the main window page?-CodePudding

In Win UI 3 I want to change the content of the MainWindow when the user clicks a button. Right now I have the MainWindow with all its content, then the user clicks a button and a new window opens, let's call it SecondWindow. I do this with:

Window secondWindow= new SecondWindow();
secondWindow.Activate();

But what I want is for SecondWindow's content to open in the main window, in place of MainWindow's content. How can I do this?

CodePudding user response：

If you want the display the contents of the secondWindow inside another window, it should be a UserControl instead of a window.

You could then simply add an instance of it as a child of the root panel of the main window:

MainWindow.xaml:

<Window ...>
    <Grid x:Name="root">
...

MainWindow.xaml.cs:

this.grid.Children.Clear();
this.grid.Children.Add(new YourUserControl());

If you define the contents directly in a window, you should add its Content to the main window like this:

Window secondWindow = new SecondWindow();
var root = secondWindow.Content;

this.grid.Children.Clear();
this.grid.Children.Add(root);

secondWindow.Close();
