I've downloaded some articles to use in my project for resizing and moving every control at runtime, but those aren't more efficient in my conditions. So I decided to make a custom panel to do that. It's useful for some projects such as report generator and more.
Using the Code
Canvas class is inherited from
Panel control and in the
OnControlAdded method of the panel, some events are used to handle moving controls.
Canvas has defined
Tracker class to handle resizing the control on the panel.
Just drag and drop the custom panel (named Canvas) on the form and put some controls to test it.
public class Canvas : Panel
protected override void OnControlAdded(System.Windows.Forms.ControlEventArgs e)
if (e.Control is Tracker)
e.Control.MouseEnter += new EventHandler(Control_MouseEnter);
e.Control.MouseLeave += new EventHandler(Control_MouseLeave);
e.Control.MouseDown += new MouseEventHandler(Control_MouseDown);
e.Control.MouseMove += new MouseEventHandler(Control_MouseMove);
e.Control.MouseUp += new MouseEventHandler(Control_MouseUp);
e.Control.LocationChanged += new EventHandler(Control_LocationChanged);
e.Control.HandleDestroyed += new EventHandler(Control_HandleDestroyed);
