Hi,
As a developer it’s always a pain to manage titles for each page of a web application :)
1 – Create an ActionFilterAttribute
/// <summary>
/// Specifies the title and keywords for the page
/// </summary>
public class HeaderAttribute : ActionFilterAttribute
{
private string _title;
public HeaderAttribute(string title)
{
_title = title;
}
public override void OnActionExecuting(ActionExecutingContext filterContext)
{
base.OnActionExecuting(filterContext);
if (filterContext != null && filterContext.Controller != null)
{
filterContext.Controller.ViewData["_Title"] = _title;
}
}
}
2 – Add the title in the Master Page
Here’s the code to add in the master page. Don’t forget to put it in all your Master Pages…
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<title><%= ViewData["_Title"]%></title>
<meta name="title" content="<%= ViewData["_Title"] %>" />
</head>
3 – Put the attribute to your actions
You can now use the attribute over a controller (each action will have the title) or an action.
[Header("My Web Site - Default Page")]
public class HomeController : BaseController
{
[Header("My Web Site - Home")]
public ActionResult Index()
{
return View();
}
// The title will be "My Web Site - Default Page"
public ActionResult Buy()
{
return View();
}
}That’s it! You can also add other specific action <meta> tags like keywords and description.
Do you have other examples that use an ActionFilterAttribute?
ReplyDeleteYes, i'm managing security with ActionFileAttribute. I will make a new blog post soon to show it. Here's the code of the attribute :
ReplyDelete///
/// Specifies that the method or class is a secured action that requires authorization before being executed.
///
public class SecuredActionAttribute : ActionFilterAttribute
{
public string Key { get; set; }
public SecuredActionAttribute(string key)
{
this.Key = key;
}
public override void OnActionExecuting(ActionExecutingContext filterContext)
{
if (!(filterContext.Controller.GetType() == typeof(HomeController) && (filterContext.RouteData.Values["action"] as string) == "Unauthorized"))
{
if (!Container.Resolve().IsAuthorized(this.Key))
{
filterContext.Result = ((GSCController)filterContext.Controller).RedirectToUnauthorized();
}
base.OnActionExecuting(filterContext);
}
}
