When you have many related functions, you can consider to group them together using Region.
Example, if you have four functions which are related to Paging, you can just add a region like below (ASP.NET 1.1, VB.NET syntax):
#Region "Paging"
Public Property CurrentPage() As Integer
' Your code here ...
End Property
Private Sub ImgBtnPrevBottom_Click(ByVal sender As Object, ByVal e As System.Web.UI.ImageClickEventArgs) Handles ImgBtnPrevBottom.Click
' Your code here ...
End Sub
Private Sub ImgBtnNextBottom_Click(ByVal sender As Object, ByVal e As System.Web.UI.ImageClickEventArgs) Handles ImgBtnNextBottom.Click
' Your code here ...
End Sub
Private Sub ItemsGet()
' Your code here ...
End Sub
#End Region
Now, go to your Visual Studio 2003. Click Edit > Outlining > Collapse to Definitions, you will see the below:
It is very simple to do, yet useful.
