To add a custom property to a web part, you will need to add some lines to get it working. The items in red will be additional to the basic web part project. Don't forget to add the references to the project as well.

 

Imports System.Xml.Serialization

Imports System.ComponentModel
Imports System.Web.UI.HtmlControls

 

Namespace TestPart
    <Guid("aae404b2-ff7e-4b0f-9dec-a215cf47d907"), DefaultProperty("Text"), ToolboxData("<{0}:StaffDirectory runat=server></{0}:StaffDirectory>"), XmlRoot(Namespace:="TestPart")> _
    Public Class TestPart
        Inherits System.Web.UI.WebControls.WebParts.WebPart

        'This is all part of the custom property definition
        Private Const _defaultText As String = ""
        Private _NumNewsItems As String = _defaultText

        <Browsable(True), Category("Miscellaneous"), DefaultValue(_defaultText), WebPartStorage(Storage.Personal), FriendlyName("Text"), Description("Text Property")> _
        Public Property NumNewsItems() As Integer
            Get
                Return _NumNewsItems
            End Get
            Set(ByVal itemValue As Integer)
                _NumNewsItems = itemValue
            End Set
        End Property

        'Web Part Title
        Private Const _defaultTitle As String = ""
        Private _NewsTitle As String

        <Browsable(True), Category("Miscellaneous"), DefaultValue(_defaultTitle), WebPartStorage(Storage.Personal), FriendlyName("Text"), Description("Text Property")> _
        Public Property NewsTitle() As String
            Get
                Return _NewsTitle
            End Get
            Set(ByVal itemValue As String)
                _NewsTitle = itemValue
            End Set
        End Property

 

These properties are then set in the page like this:

 

<TestPart:TestPart runat="server" ID="TestPart1" NewsTitle="News and Information" NumNewsItems="5" Description="Latest new and Info" NoNewsItems="3" Title="News &amp; Information" ImportErrorMessage="Cannot import TestPart Web Part." __MarkupType="vsattributemarkup" __WebPartId="{f4083814-edde-4dc4-958e-732c18d85257}" WebPart="true" __designer:IsClosed="false"></TestPart:TestPart>
