Steps Involved:

• Open Visual Studio 2010.
• Create an "Empty SharePoint Project".
• Right click on the solution and click on Add => New Item.
• Select "Visual Web Part" template from SharePoint 2010 installed templates.
• Entire solution looks like the following
  
  
   
• Replace CustomPropertiesVisualWP.cs file with the following code.
  
  using System;
  using System.ComponentModel;
  using System.Web;
  using System.Web.UI;
  using System.Web.UI.WebControls;
  using System.Web.UI.WebControls.WebParts;
  using Microsoft.SharePoint;
  using Microsoft.SharePoint.WebControls;

  namespace CustomProperties.CustomPropertiesVisualWP
  {
      [ToolboxItemAttribute(false)]
      public class CustomPropertiesVisualWP :WebPart
      {
          public static string _value;
          [System.Web.UI.WebControls.WebParts.WebBrowsable(true),
           System.Web.UI.WebControls.WebParts.WebDisplayName("Enter the Value"),
           System.Web.UI.WebControls.WebParts.WebDescription(""),
           System.Web.UI.WebControls.WebParts.Personalizable(
           System.Web.UI.WebControls.WebParts.PersonalizationScope.Shared),
           System.ComponentModel.Category("anavijai Custom Properties"),|
           System.ComponentModel.DefaultValue("")]

          public string _Value
          {
              get { return _value; }
              set { _value =value; }
          }

          // Visual Studio might automatically update this path when you change the Visual Web Part project item.
          private const string _ascxPath = @"~/_CONTROLTEMPLATES/CustomProperties/CustomPropertiesVisualWP/CustomPropertiesVisualWPUserControl.ascx";

          protected override void CreateChildControls()
          {
              Control control = Page.LoadControl(_ascxPath);
              Controls.Add(control);
          }
      }
  }
  

• In CustomPropertiesVisualWPUserControl.ascx I have added one label "lblResult" and button "btnClick".
• Replace CustomPropertiesVisualWPUserControl.ascx.cs with the following code.
  
  using System;
  using System.Web.UI;
  using System.Web.UI.WebControls;
  using System.Web.UI.WebControls.WebParts;
  using System.ComponentModel;

  namespace CustomProperties.CustomPropertiesVisualWP
  {
      public partial class CustomPropertiesVisualWPUserControl : UserControl
      {

          protected void Page_Load(object sender,EventArgs e)
          {
          }

          protected void btnClick_Click(object sender,EventArgs e)
          {
              lblResult.Text = CustomPropertiesVisualWP._value;
          }
      }
  }
   

• Build and deploy the solution.
   
• Go to the SharePoint Site =>Site Actions =>Edit Page =>Editing Tools => Insert =>Web Part =>Categories => Custom =>Select CustomPropertiesVisualWP.
   
• Click on Add.
   
• The web part looks like the following with a button.
  
  
   
• Edit the webpart you could see a new custom category in the webpart properties.
  
  
  
   
• Enter the value and click on Ok.
  
  
   
• In the CustomPropertiesWP click on the button.
