asp.net variables in aspx page

Question

I'm clearly missing something fundamental here but could someone explain why label 2 isn't populated?

My codebehind

public partial class namespace : System.Web.UI.Page
{
    public string TestString = "test";

    protected void Page_Load(object sender, EventArgs e)
    {
        lbl1.Text = TestString;
    }

}

my aspx text labels:

<asp:Label ID="lbl1" runat="server" /><br/>
<asp:Label ID="lbl2" runat="server" Text='<%# TestString %>' /><br />

You are missing the Page.DataBind(); in code-behind. Check the topic that Stijn mentioned — Andrei Drynov, Feb 17 '14 at 12:13

<%# %> is used for binding in data controls like this : <%# Eval("id") %>, you are trying to write a property on code front.

try this:

<asp:Label ID="lbl2" runat="server"><%= TestString %></asp:Label>
