How to move a form in c#

How can I move a form like how you click+hold the control box and move the mouse around.  I currently have my control box = false.  I have tried the function SetDesktopLocation but it will just refresh the box every point it moves and I would like to just drag it and not refresh the box at every point.  I am using a regular Windows Form.

It's not entirely clear what you want to do, but maybe these methods will help:

SuspendLayout()
...
form.Location = new System.Drawing.Point(x, y);
...
ResumeLayout()

A form with no ControlBox still has a Title Bar.  Just click and drag on that...

If you have a Borderless Form, though, then use code like this:
    public partial class Form1 : Form
    {
 
        public Form1()
        {
            InitializeComponent();
        }
 
        private const int HTCLIENT = 0x0001;
        private const int HTCAPTION = 0x0002;
        private const int WM_NCHITTEST = 0x0084;
 
        protected override void WndProc(ref Message m)
        {
            base.WndProc(ref m);
            if ((m.Msg == WM_NCHITTEST) & (m.Result.ToInt32() == HTCLIENT))
            {
                m.Result = (IntPtr)HTCAPTION;
            }
        }
 
    }

The Location, Top, and Left properties should work just fine.
Both former posts should also be accurate--a form with its ControlBox property set to false still has a title bar, which allows the user to move it. Do you mean you want to allow them to maximize and minimize the form? If so, use the following demonstrated in the short snippet below.
Hope it helps,
Nate
 

// To move both the form with both coordinates, use
formName.Location = new System.Drawing.Point(xCoordinate, yCoordinate);
// To just move its X coordinate, use
formName.Left = newXCoordinate;
// To move its Y coordinate, use
formName.Top = newYCoordinate;
 
// To maximize the form, use
formName.WindowState = FormWindowState.Maximized;
// To minimize the form, use
formName.WindowState = FormWindowState.Minimized;
// To set the form back to normal (not maximized or minimized), use
formName.WindowState = FormWindowState.Normal;

Sorry I don't think I was clear enough.
I will give you my scenario:

I want to have a borderless form slide across the screen.  The SetLocation method when I call it with the X coordinate and just add 1, it does not refresh the box until it stops.  The movement I am looking for is how you simulate someone holding down the title bar and dragging the form across the window and all the content inside is still visible.  The signature is something like this; private void SlideWindow(Form window,int startx, int starty)

hopefully this will clear up any complications

Sorry the signature is suppose to be like this; private void SlideWindow(Form window).  This will just slide the window across the screen horizontally from left to right.

"...it does not refresh the box until it stops."

INSIDE your loop, place a call to DoEvents():

    someLoopingStructure {
        window.Location = new Point(newX, newY);
        Application.DoEvents();
    }

Actually I figured it out.  I just used a Timer and on every 10ms tick, I moved the form over 1.  I just checked the Location to see if the form went off the screen.  Thanks for all the help.

That'll work too...inbetween Tick() events the pending messages will get processed allowing the form to repaint itself in each position.
