Here's my frontend.master.cs after completing all the tasks in Chapter 6. I keep getting an error when I attempt to display my default page using Chrome. The line in Bold is where I keep getting the error but I'm not sure why. Any thoughts?

Thanks in advance!

using System;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;

public partial class MasterPages_Frontend : BasePage
{
protected void Page_Load(object sender, EventArgs e)
{
if (!Page.IsPostBack)
{
string selectedTheme = Page.Theme;
HttpCookie preferredTheme = Request.Cookies.Get("PreferredTheme");
if (preferredTheme != null)
{
selectedTheme = preferredTheme.Value;
}
if (!string.IsNullOrEmpty (selectedTheme))
{
ListItem item = ThemeList.Items.FindByValue(selectedTheme);
if (item != null)
{
item.Selected = true;
}
}
}
}

protected void ThemeList_SelectedIndexChanged(object sender, EventArgs e)
{
HttpCookie preferredTheme = new HttpCookie("PreferredTheme");
preferredTheme.Expires = DateTime.Now.AddMonths(3);
preferredTheme.Value = ThemeList.SelectedValue;
Response.Cookies.Add (preferredTheme);
Response.Redirect(Request.Url.ToString());

}
}

Ah, there we go.

This page is a master page, but you let it inherit BasePage which is a Page. The two are not compatible. Just change BasePage back to MasterPage and it should work again.

Cheers,
