In .NET MVC, is there an easy way to check if I'm on the home page?
asp.net-mvc, c#, razor
Solution
One way to approach this would be to look for the specific controller in the `RouteData`. Assuming that the controller you are using for the home page is called "HomeController", then the `RouteData` for the request would contain the value "Home" for the key "Controller".
It would look something like this:
instead of (or in addition to if you have other reasons for it):
@Html.Hidden("returnUrl", Request.Url.AbsoluteUri)
you would have:
@Html.Hidden("referrer", Request.RequestContext.RouteData.Values['Controller'])
and your controller would look like:
[HttpPost]
public ActionResult LogOnInt(LogOnModel model)
{
if (model.referrer = "Home")
{
return Json(new { redirectToUrl = @Url.Action("Index","Home")});
}
}
This would eliminate the need for using `.Contains()`
Update:
You could also eliminate the need for a hidden field (and thereby reduce overall page-weight for what would seem like every page in your application) by mapping the referrer url (`Request.UrlReferrer.AbsoluteUri`) to a route. There is a post about that here.
How to get RouteData by URL?
The idea would be to use the mvc engine to map a referrer url to an MVC route in the `LogOnInt` method, allowing the code to be entirely self contained.
This would probably be cleaner than putting the controller name and action name out there for the world to see along with scripting to push it back to the server.
Problem
I need to take a particular action if a user logs in from the home page. In my LogOnModel, I have a hidden field: ``` @Html.Hidden("returnUrl", Request.Url.AbsoluteUri) ``` In my Controller, I need to check if that value is the Home page or not. In the example below, I'm checking to see if the user is on a particular page ("Account/ResetPassword"). Is there a way to check to see if they're on the home page without resorting to regular expressions? ``` [HttpPost] public ActionResult LogOnInt(LogOnModel model) { if (model.returnUrl.Contains("/Account/ResetPassword")) { return Json(new { redirectToUrl = @Url.Action("Index","Home")}); } ``` Any ideas? A million thanks!
