Make forms fit to every size of screen

Question

I finished developing my first windows forms application in c#, but when running it on a different Computer with a different screen size, the controls are not where they are supposed to be.

I used

this.WindowState = FormWindowState.Maximized;

to maximize the screen, but when doing this the form is just extended at the bottom and the controls stay at the same position.

HI For responsive design 1st create below class

 public class Resolution
    {
        float heightRatio = new float();
        float widthRatio = new float();
        int standardHeight, standardWidth;
        public void ResizeForm(Form objForm, int DesignerHeight, int DesignerWidth)
        {
            standardHeight = DesignerHeight;
            standardWidth = DesignerWidth;
            int presentHeight = Screen.PrimaryScreen.WorkingArea.Height;//.Bounds.Height;
            int presentWidth = Screen.PrimaryScreen.Bounds.Width;
            heightRatio = (float)((float)presentHeight / (float)standardHeight);
            widthRatio = (float)((float)presentWidth / (float)standardWidth);
            objForm.AutoScaleMode = AutoScaleMode.None;
            objForm.Scale(new SizeF(widthRatio, heightRatio));
            foreach (Control c in objForm.Controls)
            {
                if (c.HasChildren)
                {
                    ResizeControlStore(c);
                }
                else
                {
                    c.Font = new Font(c.Font.FontFamily, c.Font.Size * heightRatio, c.Font.Style, c.Font.Unit, ((byte)(0)));
                }
            }
            objForm.Font = new Font(objForm.Font.FontFamily, objForm.Font.Size * heightRatio, objForm.Font.Style, objForm.Font.Unit, ((byte)(0)));
        }

        private void ResizeControlStore(Control objCtl)
        {
            if (objCtl.HasChildren)
            {
                foreach (Control cChildren in objCtl.Controls)
                {
                    if (cChildren.HasChildren)
                    {
                        ResizeControlStore(cChildren);

                    }
                    else
                    {
                        cChildren.Font = new Font(cChildren.Font.FontFamily, cChildren.Font.Size * heightRatio, cChildren.Font.Style, cChildren.Font.Unit, ((byte)(0)));
                    }
                }
                objCtl.Font = new Font(objCtl.Font.FontFamily, objCtl.Font.Size * heightRatio, objCtl.Font.Style, objCtl.Font.Unit, ((byte)(0)));
            }
            else
            {
                objCtl.Font = new Font(objCtl.Font.FontFamily, objCtl.Font.Size * heightRatio, objCtl.Font.Style, objCtl.Font.Unit, ((byte)(0)));
            }
        }
    }

then when ever yo add any form the add panel control to form and dock it to form below
InitializeComponent();

Write below code

    this.WindowState = FormWindowState.Maximized;
    int screenWidth = Screen.PrimaryScreen.Bounds.Width;
    int screenHeight = Screen.PrimaryScreen.Bounds.Height;
    Resolution objFormResizer = new Resolution();
    objFormResizer.ResizeForm(this, screenHeight, screenWidth); 

this will make form responsive as much as possible as well as create system default font as well
