Not able to wire events in user control

I am trying to add a basic user control to a web site; coming from
visual
studio 2003 this was extremely easy. I would just add the user
control and
then add the controls that I want on that user control, but I am not
able to
get a basic link button to click. This seems so ridiculously basic,
but I am
not able to get this to work. What am I missing?
 
Can you be more specific and give us some sample code? I can guarantee that
it's just as easy (and in some cases easier) in VS2005. What you're doing
works....so something else is broken.

Here is the code:

using System;
using System.Data;
using System.Configuration;
using System.Collections;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.Web.UI.HtmlControls;
using CustomDesignCabinetry.Components;

public partial class controls_KitchenCabinetOrderForm :
System.Web.UI.UserControl
{
string lnkHref = "javascript:OpenBrWindow('%KitchenPage
%','winFaq','toolbar=no,location=no,status=no,menubar=no,scrollbars=yes,resizable=no','KitchenPageHeight','KitchenPageWidth','true');";

public int KitchenID
{
get { return int.Parse(this.lblKitchenID.Text); }
set
{
lblKitchenID.Text = value.ToString();
LoadKitchen();
}
}
protected void Page_Load(object sender, EventArgs e)
{
if (!Page.IsPostBack) SetItemsVisibility();

}



void lnkShow_Click(object sender, EventArgs e)
{
this.SetItemsVisibility();
}



private void SetItemsVisibility()
{
this.lnItems.Visible = !this.lnItems.Visible;
//if (this.lnItems.Visible)
// lnkShow.Text = "(hide)";
//else
// lnkShow.Text = "(show)";
}

private void LoadKitchen()
{
CustomDesignCabinetry.Components.Kitchen kit = new
Kitchen(GlobalInfo.ConnString);
kit.RetrieveKitchenInfo(this.KitchenID);
string tmp = this.lnkHref;
tmp = tmp.Replace("%KitchenPage%", kit.KitchenPage);
tmp = tmp.Replace("KitchenPageHeight",
kit.KitchenPageHeight.ToString());
tmp = tmp.Replace("KitchenPageWidth",
kit.KitchenPageWidth.ToString());
this.lnkKitchen.HRef = tmp;
this.imgKitchenDoor.Src = "../images/" + kit.DisplayImage;

DataSet ds =
kit.RetrieveKitchenCabinetsForOrderForm(this.KitchenID,
GlobalInfo.CurrentOrderID);
this.grdKitchenBrand.DataSource = ds;
this.grdKitchenBrand.DataBind();
bool FoundSaleItem = false;
foreach (DataRow dr in ds.Tables[0].Rows)
{
if(!dr.IsNull("Sale_Price"))
if (decimal.Parse(dr["Sale_Price"].ToString()) > 0)
{
FoundSaleItem = true;
break;
}
}
grdKitchenBrand.Columns[5].Visible = FoundSaleItem;
this.lnkBrand.Text = new
Brand(kit.ConnString).GetBrandName(kit.BrandID);


}

protected void lnkBrand_Click(object sender, EventArgs e)
{
this.SetItemsVisibility();
}
}


Here is the HTML:

<%@ Control Language="C#" AutoEventWireup="true"

<AlternatingRowStyle BackColor="#5C4000" />
</asp:GridView>
</td></tr>
</table>

I have tried adding like I would have found in VS2003:

override protected void OnInit(EventArgs e)
{
InitializeComponent();
base.OnInit(e);
}

private void InitializeComponent()
{
this.lnkBrand.Click += new EventHandler(this.lnkBrand_Click);
this.lnkShow.Click += new EventHandler(lnkShow_Click);
//this.Page.Load += new System.EventHandler(this.Page_Load);
}

I cannot get either lnkBrand or lnkShow to respond to click events.
This has got to be super smple, but I have been trying to figure it
out for a while.

TIA,
