Question

This is a follow up question to an answered question [here][1].

There the startup position of a WPF window was defined in XAML. Now I’m wondering how to change those properties in code? For example could I say something like:

Window1.Top = 40 in the window load event handler? Or which window event would I need to set those for it dynamically alter the starting position?

The goal is to set the windows start position dynamically before it is rendered.

This is fairly easy to do in code:

public partial class Window1 {

    public Window1()
    {
         InitializeComponent();
         this.Height = 500;
         this.Width = 500;
         this.WindowStartupLocation = WindowStartupLocation.Manual;
         this.Left = 0;
         this.Top = 0;
    }
}

You can set any of the parameters you wish, but if you’re going to set Top/Left, make sure to set WindowStatupLocation (or have it set to manual in XAML).
