Really easy:
VB Code:
Imports System
Imports System.Web
Imports System.Web.UI
Namespace IDIOT
Public Class MyComponent
Inherits Control
Dim _writewhat As String = "GO AWAY!"
Dim _bold As Boolean = False
Dim _underlined As Boolean = False
Protected Overrides Sub Render(ByVal Output As HtmlTextWriter)
Dim strBold As String
Dim strBoldEnd As String
Dim strUnderlined As String
Dim strUnderlinedEnd As String
strBold = IIf(Me.Bold, "<b>", "")
strBoldEnd = IIf(Me.Bold, "</b>", "")
strUnderlined = IIf(Me.Underlined, "<u>", "")
strUnderlinedEnd = IIf(Me.Underlined, "</u>", "")
Output.Write(strBold & strUnderlined & Me.WriteWhat & strUnderlinedEnd & strBoldEnd)
End Sub
Public Property WriteWhat() As String
Get
Return CType(ViewState("WriteWhat"), String)
End Get
Set(ByVal Value As String)
ViewState("WriteWhat") = Value
End Set
End Property
Public Property Bold() As Boolean
Get
Return CType(ViewState("Bold"), Boolean)
End Get
Set(ByVal Value As Boolean)
ViewState("Bold") = Value
End Set
End Property
Public Property Underlined() As Boolean
Get
Return CType(ViewState("Underlined"), Boolean)
End Get
Set(ByVal Value As Boolean)
ViewState("Underlined") = Value
End Set
End Property
End Class
End Namespace
Usage:
Code:
<%@ Register TagPrefix="idt" Namespace="WebDataApplicationTest.IDIOT" Assembly="WebDataApplicationTest" %>
idt:mycomponent id="MyComponent1" runat="server" WriteWhat="ppppp" EnableViewState="True" Bold="True"></idt:mycomponent>

A web control and a class are different things...
This is code for a web contro:
Code:
<%@ Control Language="vb" AutoEventWireup="false" Codebehind="HeaderCtl.ascx.vb" Inherits="MyDemoSite.HeaderWOOF" TargetSchema="http://schemas.microsoft.com/intellisense/ie5" %>
<table width="100%" bgColor="<%=Woof%>">
<tr>
<td>
<h2>Wokas Forums</h2>
<i>Woof on those growling fishes</i>
<br>
<b></b>
</td>
</tr>
<tr>
<td><asp:label id="lblDate" Runat="server"></asp:label></td>
</tr>
</table>
What mendhak posted was a class that inherrits a control. That is not a web control.
What Mendhak is alos doing is he's combines VB and HTML ouch 
These should be seperate.

Then the class to go with it is:
VB Code:
Imports System
Imports System.Web.UI
Imports System.Web.UI.WebControls
Public Class HeaderWOOF
Inherits UserControl
Public Woof As String = "red"
End Class

I do not like Datalists, or repeater or grid controls.
I have opted for the mthod of XSLT 
Works 10x better and gives you WAY more functionality and control over what happens.
