When I "View in Browser" the HorizontalPanel is hidden but, the vertical panel works fine.
I verified that I am in fact hitting the appropriate case in the switch statement that sets visible to true for the HorizontalPanel. But, when I load the page and view source, all of the code is greyed out (using Firebug) which indicates it isn't visible.
Direction.cs
Code:
public enum Direction
{
Horizontal,
Vertical
}
Banner.ascx
Code:
<%@ Control Language="C#" AutoEventWireup="true" CodeFile="Banner.ascx.cs" Inherits="Controls_Banner" %>
<asp:Panel ID="VerticalPanel" runat="server">
<a href="http://p2p.wrox.com" target="_blank">
<asp:Image ID="Image1" runat="server" ImageUrl="~/Images/Banner120x240.gif" AlternateText="This is a sample banner." />
</a>
</asp:Panel>
<asp:Panel ID="HorizontalPanel" runat="server">
<a href="http://p2p.wrox.com" target="_blank">
<asp:Image ID="Image2" runat="server" ImageUrl="~/Images/Banner468x60.gif" AlternateText="This is a sample banner." />
</a>
</asp:Panel>
Banner.ascx.cs
Code:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
public partial class Controls_Banner : System.Web.UI.UserControl
{

{
HorizontalPanel.Visible = false;
VerticalPanel.Visible = false;
switch (DisplayDirection)
{
case Direction.Horizontal:
HorizontalPanel.Visible = true;
break;
case Direction.Vertical:
VerticalPanel.Visible = true;
break;
}
}
public Direction DisplayDirection { get; set; }
}
