Question

Within the constructor of Page, I try to query its components size.

public sealed partial class MainPage : Page
{
    public MainPage()
    {
        // Get the canvas size.
        double height = canvas.ActualHeight;
        double width = canvas.ActualWidth;
    }
}

All I get in 0 height and width. May I know what is the best place to query for components’ size?

Answer 1

public sealed partial class MainPage : Page
{
    public MainPage()
    {
        this.Loaded += MainPage_Loaded;
    }

    private void MainPage_Loaded(object sender, RoutedEventArgs e)
    {
        // Get the canvas size.
        double height = canvas.ActualHeight;
        double width = canvas.ActualWidth;
    }
}
