Can you run code from a module to add items to an aspx page?

I have a combo box that I want on all my web pages. Is it possible to run a function from a module and add items to a dropdown box from the module?

I suppose the best way to do it would be to create a custom combo box and have that load the correct data for the page that it is on. Can someone point me to a good link on creating your own custom objects?

Thanks

Microsoft has tons of info on this stuff, maybe start here: http://msdn.microsoft.com/asp.net/us...s/default.aspx.

Here's an example of a custom control states drop down list:
StateDropDownList.vb:

VB Code:

Imports System
Imports System.Data
Imports System.Data.SqlClient
Imports System.Web
Imports System.Web.UI
Imports System.Web.UI.WebControls
 
Namespace CustomControls
    Public Class StateDropDownList : Inherits DropDownList
        Public Sub New()
            Me.DataBind()
        End Sub
        Public Overrides Sub DataBind()
            MyBase.DataSource = Me.getData()
            MyBase.DataTextField = "StateName"
            MyBase.DataValueField = "StateCode"
            MyBase.DataBind()
        End Sub
        Private Function getData() As DataTable
            Dim dtStates As DataTable
            If Not HttpContext.Current Is Nothing _
                And Not HttpContext.Current.Cache.Item("StateList") Is Nothing Then
                dtStates = CType(HttpContext.Current.Cache.Item("StateList"), DataTable)
            Else
                Dim cmdText As String = "Select StateName, StateCode From State"
                Dim connString As String = "user id=sa;password=sa;database=scratch;server=DeathAngel;"
                Dim cn As New SqlConnection(connString)
                Dim da As New SqlDataAdapter(cmdText, cn)
                dtStates = New DataTable
                da.Fill(dtStates)
                HttpContext.Current.Cache.Item("StateList") = dtStates
            End If
            Return dtStates
        End Function
 
    End Class
End Namespace

...and the aspx page StateDropDownListTest.aspx:

Code:

<%@ Register TagPrefix="pvb" Assembly="DeathAngel" Namespace="DeathAngel.CustomControls" %>

<html>

        <body>

                <form runat="server">

                        <pvb:StateDropDownList Runat="server"/>

                </form>

        </body>

</html>

pvb, I read some of those but I couldn't quite follow it. Could you look at this and give me a hand please?
