Newbie question, child controls are null in page_load RRS feed

    I am trying to create a custom control in VS 2005, it contains 3 textfields that are populated from an external object provided through a method.

    The markup is simply

    <%@ Control Language="C#" AutoEventWireup="true" CodeBehind="PersonInfo.ascx.cs" Inherits="UserManagement.PersonInfo" %>
        <asp:TextBox ID="txtbox_Name" runat="server"></asp:TextBox><br />
        <asp:TextBox ID="txtbox_Title" runat="server"></asp:TextBox><br />
        <asp:TextBox ID="txtbox_Mobile" runat="server"></asp:TextBox>

    and the codebehind looks like this (imports excluded):

        public partial class PersonInfo : System.Web.UI.UserControl
            public string Name { get { return txtbox_Name.Text; } private set { txtbox_Name.Text = value; } }
            public string Title { get { return txtbox_Title.Text; } private set { txtbox_Title.Text = value; } }
            public string Mobile { get { return txtbox_Mobile.Text; } private set { txtbox_Mobile.Text = value; } }
            protected void Page_Load(object sender, EventArgs e)
            public void SetValues(Person person)
                Name = string.Format("{0} {1}", person.Fornavn, person.Etternavn);
                Mobile = person.Mobil;
                Title = person.Title;

    I've tried to set a breakpoint on both Page_Load and SetValues method, but when the execution enters these methods, the child controls: txtbox_Name, txtbox_Title and txtbox_Mobile are all null. I have also tried to invoke EnsureChildControls in the Page_Load method, without any luck.

    My question is simply put, how do I get these controls to be initialized, so I can set their values?

    Any help would be greatly appreciated.

    You're creating a user control, which is somewhat different to a custom control, but looking at the code and markup, I cant' see where it should fail. Mind you, if you can show us the markup for the Web Form, on which you place the User Control, then we might see a different story.
