How to autosize User control when it's shown

Hello, I have a Winforms project with a bunch of User controls. I'd like the user control to move itself to be at the 1,1 position relative to its container (whether it's a form or a Panel control). And resize itself to be able to fit half the container.

What event can I respond to in the UserControl to be able to do this without any code having to be written in the container (e.g. the form or panel).

From stackoverflow

• The Paint event should work, unless I'm missing something.

• You could use the basic Load event.

  The code could be like this:

  private void UserControl1_Load(object sender, EventArgs e)
  {
      Control parent = this.Parent;
      if (parent != null)
      {
          this.Location = new Point(1, 1);
          this.Width = (parent.Width / 2);
          this.Height = (parent.Height / 2);
      }
  }
