Hello
loop.vb
Public Class loopClass
Inherits System.Web.UI.Page
Protected lblid As System.Web.UI.WebControls.Label
Public sub Page_Load()
Dim i as integer = 1
Do while i <10
i+=1
lblid.Text = i
Loop
End Sub
loop.aspx
<%@ Page Language="VB" Inherits="loopClass" Src="loop.vb" %>
<html>
<body>
<form id="Form" runat="server">
<asp:label ID="lblid" runat="server" />
</form>
</body>
</html>
using the above code i only get the last item in the loop displayed (in
this case 10)
how do loops work in 'codebehind' so that i would display 1 2 3 4 5 6 7 8
9 10

hello
because you have just one label and it can show just one value it is clear that you can see just the last one.so you have to declare
an arry (here with 10 items) or listbox to show all your outputs!
happy programming!

I don't know ASPX well yet but can see the problem.
Each time you assign i to lblid.Text you are overwriting the original
value.
You must concatinate them together, keeping the original value.
lblid.Text =3D lblid.Text + " " + i
I don't know if the shorthand works in VB like
lblid.Text +=3D " " + i
