How To? Programmaticall y Set Theme For Master Page


I have tried to programmaticall y set the theme for my master page by
putting code in a "Page_PreIn it" fuction in the master page's code
behind. However, when I set a breakpoint there and run the app, the
breakpoint is never hit. Of course my theme is not being applied.

The above procedure works fine for any content page, but obviously
doesn't work for my master page. So, how does one properly and
programmaticall y set a theme for a master page?

Try using a base class that inherits from System.Web.UI.P age and of course
all content pages then inherit from the base class. Leave the code in the
Master alone. If your using Membership, Roles and Profiles you'll have to
use a cookie and the Profile to store the preferred Theme. Here's some code
from my base class to get started...

protected void Page_PreInit(ob ject sender, EventArgs e)

#region Theme Selection...
// This region sets the Theme.
// A cookie is used to persist the selected Theme which reloads the
// for logged in users who would otherwise have to log in and
// their preferred Theme. The Theme is also stored in the Profile.
If the
// cookie is not found the preferred Theme is retrieved from the
// and the cookie is restored. The cookie also enables anonymous
// to persist a preferred Theme for a short period of time.

String preferredTheme;

// Get the selected theme from the cookie if the cookie is found.
if (Request.Cookie s["selectedTh eme"] != null)
preferredTheme = Request.Cookies["selectedTh eme"].Value;

// Set the Theme.
switch (preferredTheme )
case "SmokeyBlue s":
this.Theme = "SmokeyBlue s";
case "WisconsinAutum n":
this.Theme = "WisconsinAutum n";
this.Theme = "SmokeyBlue s";
// The cookie was not found so the Theme is retrieved from the

// NOTE: Profile information is associated with the current user
based upon the
// identity of the user. By default, ASP.NET uses the
Page.User.Ident ity.Name
// within the current HttpContext as the key to store data. By
// profiles are available only for authenticated users.

ProfileCommon pc = (ProfileCommon) HttpContext.Cur rent.Profile;

if (pc.UserName != null)
preferredTheme = pc.LoggedInUser .SelectedTheme. ToString();
if (preferredTheme != null && preferredTheme. Length > 0)
//Set the preferred theme
this.Theme = preferredTheme;

if (Request.Cookie s["selectedTh eme"] == null)
// The Theme is only restored from the Profile when the
// is not found. Since we restored the Theme using the
// we also have to restore the cookie.
HttpCookie selectedTheme = new
HttpCookie("sel ectedTheme");
selectedTheme.V alue = preferredTheme;
Response.Cookie s.Add(selectedT heme);
selectedTheme.E xpires = DateTime.Now.Ad dYears(10);


}// Page_PreInit

Hi, I've a a site with nested master pages and content pages. I tried using a theme with a stylesheet in the app_themes directory referencing it in the web.config file from a pages tag theme attribute. This works for the content pages, but it doesn't seem able to apply the styles to the top master page even though I did set the master head tag to runat server. Is this by design? If so, what is the best way to apply styles to the top...
