Probably your page displayed from cache, so the code not executed. Remove the page from the cache that it should work as expected...

For no caching in the browser

In page load we will use the below code

Response.Cache.SetCacheability(HttpCacheability.NoCache);
Response.Cache.SetExpires(DateTime.UtcNow.AddHours(-1));
Response.Cache.SetNoStore();

One more thing we need to keep in mind that in master content page application, we need to check the username and password for not null in the page load of master page. If null it will always redirect to the login page.
