Événement Closed vs Closing

Closing est appelé juste après la méthode Window.Close().
La gestion de l’événement Closing permet d’annuler la fermeture de la fenêtre.

void Window_Closing(object sender, CancelEventArgs e) { e.Cancel = true;

Closed est lui appelé juste avant que le fenêtre ne se ferme.

Maximiser une fenêtre

<Window WindowState="Maximized">

Application.Current.MainWindow.WindowState = WindowState.Maximized;

Héritage de fenêtre

Ici Window1 hérite de WindowBase, cela n'est possible que si WindowsBase ne contient pas de XAML.

namespace Vues { public class WindowBase : Window { ... } public class Window1 : WindowBase { ... } }

<vues:WindowBase x:Class="Vues.Windows1" xmlns:vues="clr-namespace:Vues">

Open a child window

MainWindow.xaml

<Button Command="{Binding OpenCommand}" />

MainWindowViewModel.cs

public ICommand OpenCommand { get; set; } public MainWindowViewModel() { OpenCommand = new DelegateCommand(this.Open); } private void Open() { var childWindow = new ChildWindow(); var childWindowReturnedValue = childWindow.ShowDialog(); }

ChildWindow.xaml

<Window x:Class="WpfApp1.ChildWindow" x:Name="Window"> <DockPanel HorizontalAlignment="Center"> <StackPanel Orientation="Horizontal" DockPanel.Dock="Bottom"> <!-- IsDefault="True" makes the focus on the button, so press enter makes the button click --> <Button Content="Ok" IsDefault="True" Command="{Binding OkCommand}" CommandParameter="{Binding ElementName=Window} "/> <Button Content="Cancel" IsCancel="True" /> <!-- IsCancel="True" makes the button close the window when clicked and return false --> </StackPanel> <TextBlock> Some text ... </TextBlock>

ChildWindowViewModel.cs

public ICommand OkCommand { get; set; } public ChildWindowViewModel() { OkCommand = new DelegateCommand<Window>(this.Ok); } private void Ok(Window window) { // set a value to DialogResult to close the window window.DialogResult = true; }

Code-behind

// depuis le code behind var childWindow = new Window() { Owner = this }; // définir la fenêtre courante comme parente childWindow.Height = 100; childWindow.Width = 50; var stackPanel = new StackPanel(); var button = new Button(); button.Content = "Ok"; // le bouton de validation est celui qui possède la propriété IsDefault à true button.IsDefault = true; button.Click += (_sender, _e) => { window.DialogResult = true; window.Close(); }; stackPanel.Children.Add(button); childWindow.Content = stackPanel; // définit la position de la fenêtre childWindow.WindowStartupLocation = WindowStartupLocation.CenterScreen; childWindow.ShowDialog();

Renvoit la window contenant le UserControl

// renvoit la window contenant le UserControl Window.GetWindow(monUserControl);

Padding

Ajouter une border transparente fait office de padding.

<Window> <Border BorderThickness="4" BorderBrush="Transparent">
