How to edit the MainWindow constructor of a WPF application?

To edit the MainWindow constructor of a WPF application, follow these steps:

  1. Open the XAML file for your MainWindow. It should be named MainWindow.xaml.

  2. Locate the MainWindow tag in the XAML code. It should look like this:

    <Window x:Class="YourNamespace.MainWindow" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Title="MainWindow" Height="350" Width="525"> <!-- Other XAML code here --> </Window>

  3. Add a Loaded attribute to the MainWindow tag, like this:

    <Window x:Class="YourNamespace.MainWindow" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Title="MainWindow" Height="350" Width="525" Loaded="Window_Loaded"> <!-- Other XAML code here --> </Window>

  4. Save the XAML file and switch to the code-behind file for your MainWindow. It should be named MainWindow.xaml.cs.

  5. Locate the MainWindow constructor in the code-behind file. It should look like this:

    public partial class MainWindow : Window { public MainWindow() { InitializeComponent(); } }

  6. Add a Window_Loaded event handler to the constructor, like this:

    public partial class MainWindow : Window { public MainWindow() { InitializeComponent(); Loaded += Window_Loaded; } private void Window_Loaded(object sender, RoutedEventArgs e) { // Code to run when the window is loaded goes here } }

  7. Save the code-behind file.

Now you can add code to the Window_Loaded event handler to run when the MainWindow is loaded.
