Standarized Forms C# with inheritance

I'm making an application for a touchscreen-computer-scanner CK3; I made severa开发者_运维技巧l standardized forms(list, detail, dialog) and I made em inherit from a Class I made that is inheriting from the Form class.

 public class Formulier : Form
{
    private const int WIDTH = 248;
    private const int HEIGHT = 328;

    public Formulier()
    {
        this.Font = new Font("Microsoft Sans Serif", 10f);
        //this.Height = HEIGHT;
        //this.Width = WIDTH;
        //this.MinimumSize = new Size(Width, Height);
        this.FormBorderStyle = FormBorderStyle.None;
        this.WindowState = FormWindowState.Maximized;
    }

}
namespace WarehouseManagement {
public partial class FormPikbonDetail : Formulier {
    public FormPikbonDetail() {
        InitializeComponent();
    }
}
}

It worked fine for the Font and the FormBorderStyle but the WindowState didn't get maximized. What am I doing wrong here?

Change the WindowState after the form is actually really created - constructor is too early. By BrokenGlass
