In Chapter 6 page 231(Try it out):

I am not getting any errors, the problem is the browser is not able to display the theme i choose form the dropdown list. It does not display the combination of both themes as mentioned in the book.

I have already removed the styleSheetTheme attribute but browser displays the default as in the web.config file beteen page element.

Can someone help me out with this one please.

Thanks in advance for your help.

Hi Tariq,

Is the page you use to try this out inheriting your own BasePage? And how does the code for the BasePage look?

Thanks very much for the quick reply;

I am quite sure that it is inheriting from the BasePage, i could be wrong.
Here is the code for the base page:

using System;
using System.Web;

public class BasePage : System.Web.UI.Page
{

private void Page_PreInit(object sender, EventArgs e)
{
HttpCookie preferredTheme = Request.Cookies.Get("PrererredTheme");
if (preferredTheme != null)
{
Page.Theme = preferredTheme.Value;
}
}

private void Page_PreRender(object sender, EventArgs e)
{
if (this.Title == "Untitled Page" || string.IsNullOrEmpty(this.Title))
{
throw new Exception("Page title Cannot be \"Untitled Page\" or an empty string.");
}
}
public BasePage()
{
this.PreRender += new EventHandler(Page_PreRender);
this.PreInit += new EventHandler(Page_PreInit);
}
}

And theme in the browser is what ever is in my configration file which looks like this.

configuration>

<system.web>
<pages theme="DarkGrey"></pages>
<compilation debug="false" targetFramework="4.0" />
</system.web>

</configuration>
As this is DarkGrey now so browser displays the dark gray if it was Monochrome browser displays the Monochorme and brower does not displays the theme i select form the dropdown list.

Hi Tariq,

Take a look at this:

HttpCookie preferredTheme = Request.Cookies.Get("PrererredTheme");

You're reading a cookie called PrererredTheme instead of PreferredTheme.

If you haven't made the same spelling mistake in the page that sets the coookie, you're reading a cookie you never set....

Hope this helps,

Imar
