Accessing Variable for use in ascx in Code Behind

Question

I have a simple .ascx page that looks like this:

<%@ Control Language="C#" AutoEventWireup="true" CodeBehind="ctl_dataLookup.ascx.cs" Inherits="ctl_dataLookup" %>

<div>
    <h1>Data Lookup</h1>

    <p><%= d1 %></p>
</div>

The code behind page looks like this, and DoDataLookup method is called at the start of running this page:

public partial class ctl_dataLookup : BaseDomainControl
{

        private string d1;
        public string D1 { get { return d1; } }

        protected void Page_Load(object sender, EventArgs e)
        {
            this.Visible = false;
            this.DataBind();
        }

        public void DoDataLookup(int DomainId, string DomainName)
        {
            this.Visible = true;

            d1 = "TEST DOMAIN";
        }


}

However, the <%= d1 %> always ends up looking like this when the page is rendered (System.Web.UI.WebControls.Label):

I've looked at countless examples of this on Stack Overflow, but it looks as though I'm doing everything right... Is there any obvious reason why this is happening?

Answer 1

Try using D1, not the private d1 variable. Hope this works.

Thanks
