  Add designer support to Label for a better UI designer

Introduction

While designing a windows form in Visual Studio .NET I always find the standard Label control difficult to manage and creating ultra high fine layout/UI. The Label control does not show the border in Visual Studio designer. It?s difficult to guess the size and placement of all labels in a single look.

Take case of the below UI



I really can?t judge how the labels are placed here. It may be a mess like this one



This could be overcome by designing simple.. really simple Label by placing just 4 more lines of code to Standard Label. I like the cleanness in below UI. This one designed using the Label produced after just 4 lines of code.



Source Code

To do this simply draw a rectangle along the sides of Label while it is in design mode. Here is the source code for this Label.
using System;
using System.Drawing;
using System.Windows.Forms;

namespace Owf
{
  public class MyLabel : Label
  {
    public MyLabel()
    {
      InitializeComponent();
    }

    private void InitializeComponent()
    {
      this.SuspendLayout();
      // 
      // MyLabel
      // 
      this.Paint += new System.Windows.Forms.PaintEventHandler(this.MyLabel_Paint);
      this.ResumeLayout(false);

    }

    private void MyLabel_Paint(object sender, PaintEventArgs e)
    {
      if (this.DesignMode)
      {
        using (Pen pen = new Pen(Color.Gray))
        {
          pen.DashStyle = System.Drawing.Drawing2D.DashStyle.Dash;
          e.Graphics.DrawRectangle(pen, 0, 0, this.Width - 1, this.Height - 1);
        }
      }
    }
  }
}
