Resizing a panel in C#, Windows Forms

Question

How can I enable users to resize a panel at runtime by dragging a corner?

Answer 1

You could intercept the mouse location and the click.. if it's in a corner then set a resizing boolean and then on the mousemove event you could implement something like this..

  if (_resizing)
  {
    this.Height = top + e.Y;
    this.Width = width + e.X;
  }

Answer 2

I don't know about dragging corners, but you could dock the panel and use splitters to provide a place for users to resize the docked regions.
