Within your user control create a public property called Text.

[xthml]
using System;

namespace WebApplication1
{
    public partial class WebUserControl1 : System.Web.UI.UserControl
    {
        public string Text = string.Empty;

        protected void Page_Load(object sender, EventArgs e)
        {
            Response.Write(“this is a test ” + Text);
        }
    }
}
[/xhtml]

Within your web form create a reference to your user control and set the ‘Text’ property.
