Mover un control arrastrándolo con el mouse en C#

Laura, miembro de este staff, nos hizo el favor de redactar esta reseña ya que domina perfectamente el tema.

Solución:

Todo lo que necesita:

public partial class Form1 : Form

    public Form1()
    
        InitializeComponent();
    


    private Point MouseDownLocation;


    private void pictureBox1_MouseDown(object sender, MouseEventArgs e)
    
        if (e.Button == System.Windows.Forms.MouseButtons.Left)
        
            MouseDownLocation = e.Location;
        
    

    private void pictureBox1_MouseMove(object sender, MouseEventArgs e)
    
        if (e.Button == System.Windows.Forms.MouseButtons.Left)
        
            pictureBox1.Left = e.X + pictureBox1.Left - MouseDownLocation.X;
            pictureBox1.Top = e.Y + pictureBox1.Top - MouseDownLocation.Y;
        
    

También puedes usar la extensión:

public static class CmponentsExtensions

  //Management of mouse drag and drop
    #region Menu and Mouse
    private static bool mouseDown;
    private static Point lastLocation;

    /// 

    /// To enable control to be moved around with mouse
    /// 
    /// 
    /// 
    public static void moveItselfWithMouse(this T control) where T: Control
     
        control.MouseDown += (o, e)=>  mouseDown = true; lastLocation = e.Location; ;
        control.MouseMove += (o, e) => 
        
            if (mouseDown)
            
                control.Location = new Point((control.Location.X - lastLocation.X) + e.X, (control.Location.Y - lastLocation.Y) + e.Y);
                control.Update();
            
        ;
        control.MouseUp += (o, e) =>  mouseDown = false;  ;
    


    public static void moveOtherWithMouse(this T control, Control movedObject) where T : Control
    
        control.MouseDown += (o, e) =>  mouseDown = true; lastLocation = e.Location; ;
        control.MouseMove += (o, e) =>
        
            if (mouseDown)
             
                movedObject.Location = new Point((movedObject.Location.X - lastLocation.X) + e.X, (movedObject.Location.Y - lastLocation.Y) + e.Y);
                movedObject.Update();
            
        ;
        control.MouseUp += (o, e) =>  mouseDown = false; ;
    

    #endregion

Entonces necesitas usarlo con algo de control:

En este caso, pictureBox1 movió todo el formulario

pictureBox1.moveOtherWithMouse(this);

En este caso solo mueves pictureBox:

pictureBox1.moveItselfWithMouse();

intente esto para mover el control de PictureBox en tiempo de ejecución usando el mouse

 private void pictureBox7_MouseDown(object sender, System.Windows.Forms.MouseEventArgs e)
        
            if (e.Button == MouseButtons.Left)
            
                xPos = e.X;
                yPos = e.Y;
            
        

        private void pictureBox7_MouseMove(object sender, System.Windows.Forms.MouseEventArgs e)
        
            PictureBox p = sender as PictureBox;

            if (p != null)
            
                if (e.Button == MouseButtons.Left)
                
                    p.Top += (e.Y - yPos);
                    p.Left += (e.X - xPos);
                
            

        

Si piensas que ha resultado útil nuestro artículo, sería de mucha ayuda si lo compartes con más desarrolladores de este modo contrubuyes a difundir nuestra información.
