i have creating url using routelink.
@Html.RouteLink("Edit", "PageWithId",
new
{
controller = "Customers",
action = "Edit",
id = item.CustomerID,
page = ViewBag.CurrentPage
})
i am using this routing PageWithId with route link
routes.MapRoute(
name: "PageWithId",
url: "{controller}/{action}/{page}/{id}",
defaults: new { controller = "Customers", action = "Edit", page = UrlParameter.Optional, id = UrlParameter.Optional }
);
i have 3 routing code in route.config file. here is all
routes.MapRoute(
name: "PageWithSort",
url: "{controller}/{action}/{page}/{SortColumn}/{CurrentSort}",
defaults: new { action = "Index", page = UrlParameter.Optional, SortColumn = UrlParameter.Optional, CurrentSort = UrlParameter.Optional }
);
routes.MapRoute(
name: "PageWithId",
url: "{controller}/{action}/{page}/{id}",
defaults: new { controller = "Customers", action = "Edit", page = UrlParameter.Optional, id = UrlParameter.Optional }
);
routes.MapRoute(
name: "Default",
url: "{controller}/{action}/{id}",
defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional }
);
when i run my program the route link generate url like http://localhost:55831/Customers/Edit/1/ALFKI
when i click on the link the Edit action is getting called but customer id is getting null where as ALFKI is there in url as customer id.
here is my edit action details
public ActionResult Edit(string id, int page)
{
if (id == null)
{
return new HttpStatusCodeResult(HttpStatusCode.BadRequest);
}
Customer customer = db.Customers.Find(id);
if (customer == null)
{
return HttpNotFound();
}
ViewBag.CurrentPage = page;
return View(customer);
}
please tell me why id is getting null when ALFKI as passing as customer id?
thanks

The URL /Customers/Edit/1/ALFKI matches both the PageWithSort and PageWithId routes. As a result, the first matching route will be selected - PageWithSort - and the ALFKI string will be available as a parameter called SortColumn.
Since your action doesn't take a parameter called SortColumn, and the route doesn't contain any data for a parameter called id, the parameter will be set to null.
You can see this for yourself using the ASP.NET Routing Debugger[^] package.
You'll need to rename the parameters on your actions so that they match the parameters in the route. Since the PageWithSort route will match anything that the other two routes would, that's the one you need to match.

HI,
suppose i am inserting new records in db and PK field may be identity type of may not. i am showing 10 records per page through skip() and take(). now how could i calculate page no where newly inserted record will appear.
give me some direction. thanks

It depends on many factors, such as indexing, sort order, etc.
The rest of it is clear mathematics.

i have seen a example of asp.net mvc routing code where two controller name has been referenced.
routes.MapRoute(
name: "test",
url: "{controller}/{action}/{page}/{id}",
defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional }
defaults: new { action = "Index" }
);
just started working with asp.net mvc. so curious to know that what is the objective to mention controller or action name twice ?
in above example there is two defaults....when and why it is required.
just requesting anyone can explain the same with a nice example. thanks in advance

I don't know where you got that example from, but it's not valid C#. Not only are you missing a comma between the last two parameters, but you've specified the same named parameter twice.
Try to compile that code, and you'll get:
CS1740 Named argument 'defaults' cannot be specified multiple times

HI Sir,
please check this url asp.net mvc 4 - Using Url.RouteUrl() with Route Names in an Area - Stack Overflow[^]
in the above url you will see a example where two controller name has been mentioned.
here a small snippet.
context.MapRoute(
"UserHome",
"User/{id}",
new { action = "Index", controller = "Home", area = "User", id = 0,
httproute = true },
new { controller = @"Home", id = @"\d+" }
);
looking for your further guidance. thanks

That doesn't match the code in your question.
This code is calling the MapRoute(name, url, defaults, constraints)[^] overload. The second anonymous object represents the constrains on the route.
See: ASP.NET Routing: Adding Constraints to Routes[^]
It would probably be worth reading most of that article. (You can ignore the "Web Forms" section.)

sir can you give some direction that which area i need to fix in my code.
|
|
|
|

What code? You've shown two different code blocks, one of which won't compile. And you haven't described a problem that needs fixing with either one.

Please do not post in multiple places: it duplicates work and that annoys people.
You already have this in QA, so leave it there.

My routing code is not working.
i am showing data in tabular format with sorting and pagination. my solution is working. when i hover mouse on column then url looks like
http://localhost:55831/Customers?page=2&SortColumn=CompanyName&CurrentSort=ContactName
when i click on pagination numeric link then url looks like
http://localhost:55831/Customers?page=3&SortColumn=ContactName
i want my url should look like
1) http://localhost:55831/Customers/2/CompanyName/ContactName
2) http://localhost:55831/Customers/3/ContactName
so i add one routing code. here it is
routes.MapRoute(
name: null,
url: "Customers/{page}/{SortColumn}/{CurrentSort}",
defaults: new
{
action = "Index",
page = UrlParameter.Optional,
SortColumn = UrlParameter.Optional,
CurrentSort = UrlParameter.Optional
}
);
after adding the above routing code url looks bit weird. now url looks like
http:
http:
so when i click on above links then i am not redirecting to proper controller and action rather getting error.
so it means there is some problem in code which i added as routing in route.config.cs file.
my full routing code
routes.MapRoute(
name: null,
url: "{controller}/{action}/{page}/{SortColumn}/{CurrentSort}",
defaults: new
{
action = "Index",
page = UrlParameter.Optional,
SortColumn = UrlParameter.Optional,
CurrentSort = UrlParameter.Optional
}
);
routes.MapRoute(
name: null,
url: "{controller}/{action}/{page}/{id}",
defaults: new
{
controller = "Home",
action = "Index",
id = UrlParameter.Optional,
page = UrlParameter.Optional,
}
);
routes.MapRoute(
name: "Default",
url: "{controller}/{action}/{id}",
defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional }
);
so please help me to get my desired url what i mention above. thanks

few questions about local db and sql express db.
1) i found many time a db with .mdf extension in app_data folder. that db is local db or sql express db?
2) is there any process which help me to determine that db type in app_data folder ?
3) what is the difference between local db and sql express db? or both is same ?
4) what is sql compact db and how it is different from local db and sql express db?
please answer point wise. thanks

The type of files stored in that folder depend on the application - i.e. it's up to the app developer to store whatever they want there - it may be an Access file, an SQLite file, or maybe just an XML or JSON file. You can usually tell by the file extension what sort it is.
