title: Why when adding new properties to custom control the properties not show?
body: <p>I have a library class and i added a new User Control and added a code:</p>
  
  <pre><code>using System;
  using System.Collections.Generic;
  using System.ComponentModel;
  using System.Drawing;
  using System.Data;
  using System.Linq;
  using System.Text;
  using System.Threading.Tasks;
  using System.Windows.Forms;
  
  namespace CustomControl
  {
      public partial class ExtendedTextBox : UserControl
      {
          [PropertyTab("Data")]
          [Browsable(true)]
          [Category("Extended Properties")]
          [Description("Set TextBox border Color")]
  
          public string Texts
          {
              get { return textBox.Text; }
              set { textBox.Text = value; }
          }
  
          private TextBox textBox;
  
          public ExtendedTextBox()
          {
              InitializeComponent();
  
              textBox = new TextBox();
              textBox.Multiline = true;
              textBox.BorderStyle = BorderStyle.None;
              this.Controls.Add(textBox);
          }
  
          private void ExtendedTextBox_Load(object sender, EventArgs e)
          {
  
          }
  
          private void ExtendedTextBox_Paint(object sender, PaintEventArgs e)
          {
              ControlPaint.DrawBorder(e.Graphics, this.ClientRectangle, Color.Red, ButtonBorderStyle.Solid);
          }
  
          private void ExtendedTextBox_Resize(object sender, EventArgs e)
          {
              textBox.Size = new Size(this.Width - 3, this.Height - 2);
              textBox.Location = new Point(2, 1);
          }
      }
  }
  </code></pre>
  
  <p>When i add the dll file to another windows forms project i drag the control to the designer but in the solution explorer under the control properties i don't see Data and not Extended Properties and not Set TextBox border Color.</p>
  
  <p>I wanted to add a property that when you click on it will give you a sub property and click on that will open the colors pattern so you can change/set a new color to the paint event.</p>
  
  <p>Now in the paint event it's set to Red but i want that there will be a property so the user can set any color.</p>
