I need to use routing with parameters in my ASP.NET application.
public class Global : System.Web.HttpApplication
{
void Application_Start(object sender, EventArgs e)
Then, by navigating to "/Profile" I want to get on Page_Load method Request.Params["Id"] as null and by navigating to "/Profile/1", Request.Params["Id"] as "1".
I consider the following an error, and not a feature:
When posting a request, any parameters are held in the HttpContext.Request.Form as key/value pairs. This is perfectly fine for the recipient of the request. Unfortunately, however, further down the chain these values still exist and take precedent in binding over new parameters created during processing.
This is obvious in the RenderAction scenario. If a new parameter is created in a view and passed through RenderAction, if the parameter has the same name as one of the initial request parameters (or a form field for that matter), then MVC Binding will bind the initial request form value to the Action being called, and not the new parameter being defined in the RenderAction call. What's even more frustrating, is there is no easy way to override the initial form values.
It really does not make sense that a value defined in one context, should live throughout the entire processing context... at least without the developer being able to determine it should remain. At a minimum, any new parameter defined in the process with the same name should either a) be received as a parameter and not a form value; or b) override the form value.
I would like to be able to type in a URL like [URL] arrive at a Details Page which parsed the "M" and the "123" from the query string and used them as params to query a Table in my Database. I've been reading my @$$ off and I can't find anything close :>

I've already implemented URL routing in my app but there are cases where I may or may not get a paramter. In particular, I'm trying to come up with a good way to handle multi-language support. For example, if my regular URL is /SomeCategory/Friendly-Topic-URL, I want to have an optional language selector at the end but I'd like to be optional. So, if I get /SomeCategory/Friendly-Topic-URL/es, that should bring up the topic in Spanish but if get nothing, that should bring up English.

My routeVideo.aspx page has caching setting:
<%@ OutputCache Duration="10" Location="ServerAndClient" VaryByParam="id" %>
But when I request http://localhost/video/6/example1 and http://localhost/video/6/example2 after this, the page is created again. So I think VaryByParam works for * but I only want compile when id changes. Is there a way to define routing parameters at VaryByParam?

I have some routes defined in global.asax according to which the page is redirected.
Global.asax
void Application_Start(object sender, EventArgs e) {
RegisterRoute(System.Web.Routing.RouteTable.Routes);
} void RegisterRoute(RouteCollection routes) {
routes.MapPageRoute("MainCategory", "{state}/{mcat}", "~/MainCategory.aspx");
routes.MapPageRoute("carriers", "{state}/{mcat}/{dcat}", "~/carriers.aspx");
routes.MapPageRoute("carrierdevices", "{state}/{mcat}/{dcat}/{carrier}", "~/carrieritems.aspx");
routes.MapPageRoute("cellphone", "{state}/{mcat}/{dcat}/{carrier}/{device}/{id}", "~/Catalog.aspx");
//New Rout with same parameters
routes.MapPageRoute("iphones", "{state}/{mcat}/{dcat}", "~/iphones.aspx");
}
i mean to say how to decide the destination page depending on URL Eg:1.routes.MapPageRoute("carriers", "{state}/{mcat}/{dcat}", "~/carriers.aspx"); 2.routes.MapPageRoute("iphones", "{state}/{mcat}/{dcat}", "~/iphones.aspx");
if value in URL second parameter i.e mcat=cellphone then it must redirect to carriers.aspx. and if mcat=iphone then it must redirect to iphones.aspx page.
Problem:currently if in URL there are 3 parameters then it always goes to carriers.aspx as it searches in route table for 3 parameters it redirects to carriers.aspx which need to be conditionally redirected depending on mcat valuehow to do?
I have seen demo on remove .aspx extension from url in asp.net, its a great articale, but i have few queries which i would like to ask.
How we can use same approcah when we are passing multiple values in a query string like:
"www.localhost/Category.aspx?Id=1&Name=abc"
In example shown that we need to write below code in global file like :
routes.MapPageRoute("CustomerDetails", "Customers/{CustomerId}", "~/CustomerDetails.aspx");
but what about in above case?
I've been struggling for some time now with an MVC routing issue, but I have finally reached a point where the basic routing is correct; that is, the application is invoking the correct action method and .aspx page, but the action method fails because no parameters are passed to it.
Before I show detailed screenshots of the problem, I had better provide some background. This is a bibliographic application which, among other things, analyzes text abstracts to identify unique words and the number of occurrences for each word in each document. This data will eventually be inserted into a SQL Server database, but for the time being I only want to do the calculation and display the results, on a document-by-document basis, in an .ASPX view set up for the purpose. The data structure of the application is as follows:
Collections -this is a set of fifty or so CollectionDetails items.CollectionDetails represent individual documents, in this case books in an academic library. Attributes of the CollectionDetail record are those typical of a library book--author, call number, title, year, and so on. The title and subject catalog headings are combined to form a quasi-abstract, which becomes the basis of the text analysis. In a few cases, I added additional text from Google Books or Amazon synopses and reviews.
MasterStopList contains common words such as pronouns and prepositions that we want to exclude from consideration.
We have lot of application parameters for each module in a C# .NET 4 ASP website. parameter examples: timeouts, formulae constants, thread limits per module, $ charges per usage etc. What is best out of following approaches we know: Use DB config table Use an xml. load that xml into local cache on start (and on xml change) simple constants.cs file with public const int XYZ = 123; type of key-value pairs. web.config (though i think its mostly for deployment type of config)

View 1 RepliesTo clarify, the scenarios I am looking at involve deploying ASP.NET 4 Web Forms application that employ RouteTable.Routes.MapPageRoute:
public class Global : System.Web.HttpApplication
{
public static void RegisterRoutes(RouteCollection routes)
{
RouteTable.Routes.MapPageRoute("questionnaires", "questionnaires", "~/Pages/Questionnaires/List.aspx", false);
[Code]....
Scenario 1: The application is NOT hosted as a virtual directory in an existing website, but is a stand-alone website (it is its own starting point). It has its own application pool. When deployed, it worked without any tinkering.
Scenario 2: The application is hosted as a virtual directory underneath an existing website. It also has its own application pool. However, I received 404 errors when trying to access the routes I had mapped out. Fortunately, I had experience getting MVC to work in 3.5 sp 1, so I tried that method: opened the properties dialog of the virtual director, went to the "Directory" tab, click the "Configuration" button, and added a Wildcard application map to the aspnet_isapi.dll and unchecked the "Verify that file exists" checkbox. This made it work.
My question is why did I have to add a wildcard application map in the second scenario but not the first? If it helps, the root website that hosts the virtual directory in the second scenario is set up with ASP.NET version 2.0.50727.
In an asp.net mvc application, I would like to be able to generate views, where the routing engine will create all URLs that point to a different site, i.e. change the application path.
View 1 RepliesI've been developing a asp.net/c# web application that uses .net routing with Visual Studio 2008. The project is setup to use http://localhost:17315 as the server path. I'm trying to figure out a way for a co-worker to connect to my local project from their system. When I setup the project as a virtual directory in IIS (5.1) the .net routing doesn't work correctly and I get a 404 error (http://localhost/home).Is there anyway for a user on our local network to connect to my application remotely with my current configuration? I know they can't connect to the Visual Studio Development Server, but I would think they should be able to connect if the application is setup in IIS. Maybe IIS6+ is needed for this?
View 21 RepliesI am using ASP.NET 4.0 Web Forms. I learned that, in order to optimize my Web Application for Search Engine, I must implement custom 404 page. But the way Microsoft tell us to implement custom 404 (within Web.Config file), that is not good for SEO. Microsoft says,
<customErrors mode="RemoteOnly" defaultRedirect="GenericErrorPage.htm">
<error statusCode="404" redirect="Page-Not-Found.aspx" />
</customErrors>
But when the page is not found, IIS issue 302 redirect to Page-Not-Found.aspx page which is not good. So, I implemented custom 404 page using Routing technique that is available in ASP.NET 3.5 SP1 and 4.0. I used the following router in Global.asax page
Imagine a Web Forms application with routing.
A clean page name like:
[URL]
Might have an underlying of URL of:
[URL]
If a user enters [URL] into a browser, I need to redirect to [URL]
Is this possible to do?
I can't work out a way to do this as the routing engine is not executed for a physical page and in the page.aspx Page_Load method I have no way of knowing whether the URL was entered directly or was the result of a route.
