Dodawanie kontroli/strony użytkownika do Windows Xaml programowo w WPF

Question

Chcę przełączać programowo między moimi dwoma kontrolkami użytkownika AddUsers.xaml (kontrola użytkownika) i Viewusers.xaml (kontrola użytkownika) w Window1.xaml (główne okno).

Próbuję zmienić ustawienia użytkownika poprzez Button Event w Window1.xaml. nic nie znalazłem w sieci, więc każde ciało może mi pomóc.

my Window1. XAML idzie tak

<Window x:Class="SwitchUsers.MainWindow" 
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" 
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" 
    Title="MainWindow" Height="500" Width="525"> 
<Grid> 
    <Grid.RowDefinitions> 
     <RowDefinition Height="100" /> 
     <RowDefinition Height="400*" /> 
    </Grid.RowDefinitions> 
    <StackPanel Grid.Row="0" > 
    <Button Content="Swithc User Control " Height="23" HorizontalAlignment="Right"  Margin="0,40,284,0" Name="btnSwittch" VerticalAlignment="Center" Width="168" /> 
    </StackPanel> 

    <StackPanel Grid.Row="1" > 
     <!--Here I want to display two user controls by switching from button on Top -->    
    </StackPanel> 
</Grid> 

mam dwa Elementy sterowania addUser.xaml i viewUser.xaml

adduser. Kod XAML:

<UserControl x:Class="SwitchUsers.addUser" 
     xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" 
     xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" 
     xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" 
     xmlns:d="http://schemas.microsoft.com/expression/blend/2008" 
     mc:Ignorable="d"

Answer 1

Najpierw trzeba dać panel stos nazwę

<StackPanel Name="myStack" Grid.Row="1" > 
</StackPanel> 

to trzeba coś podobnego do

public partial class MainWindow : Window 
{ 
    private addUser _addUser; 
    private viewUser _viewUser; 
    private Control _currentUser; 

    public MainWindow() 
    { 
     InitializeComponent(); 

     _addUser = new addUser(); 
     _viewUser = new viewUser(); 
     _currentUser = _viewUser; 
     myStack.Children.Add(_currentUser); 
    } 

    private void button1_Click(object sender, RoutedEventArgs e) 
    { 
     myStack.Children.Clear(); 
     if (_currentUser == _addUser) 
     { 
      _currentUser = _viewUser; 
     } 
     else 
     { 
      _currentUser = _addUser; 
     } 
     myStack.Children.Add(_currentUser); 
    } 

}
