We have been trying to implement shortcodes on an ASP.NET MVC web app that allow users to uniquely invoke a given article/page using an assigned short code.
For e.g.: www.mysite.com/power would map to an actual URL: www.mysite.com/Power/Home/.
I have created various routes throughout the site that map these shortcodes to various actions and controllers within the application. From a shortcode/route point of view, everything is working great.
I, however, noticed a couple of interesting things. I have hyperlinks that I use Url.Action method to generate the URL pointing pages. Many of these pages also have short codes associated with them. For e.g.: I have a link that says:
Go to Power page
This is a page that also has the previously mentioned short-code assigned to it. When I use Url.Action, I ideally expect it to create a link as /Power/Home/Index or /Power/Home, but since I also have a route constraint mapped to it, it now generates the link as /power.
Is there a way I can just use the actual link URL when generating links? I only want short-codes when I am sending out emails etc. I want the site to generate actual URLs.
This may or may not be possible, but I wanted to see if there were any ideas out there that I could use.

Index and Home are likely defined in your route table as defaults for the Action and Controller element. When you generate the Url it wont include the defaults if they aren't needed.
You could write your own Action overload or helper, which would allow you to take more direct control of the generated URL or action link. You could approach it from two different ways: 1) a helper to generate short-code specific urls and links, and/or 2) a helper to generate the full url and/or link. If Url.Action is returning the short-code version due to your routing configuration, I'd think a good place to start would be the second option, creating a helper/extension method that will generate the full url for you.
Here's how I solved this:
Instead of naming a route with short code to point to the action url, I made the route point to a different Controller action which would then redirect to the actual route that I want it to.
For e.g.: Originally I had the code "power" defined in the route table such that it would point to www.mysite.com/Power/Home.
Now instead of pointing it to that action - Index, controller - Home, area - Power, I make it resolve to: action - Power, Controller - Home, Area - ShortCode.
In the controller now, I simply do a RedirectToAction("Index", "Home", new { Area = "Power" });
This ensures that the actual links to /Power/Home do not resolve to the shortcode "power".
This is a simple fix increased the work by a little bit, but works like a charm.

This view suppose to show a list of hyperlinks, each pointing to an external URL. The goal is for the user to click one of these links and have their browser open a new tab with the selected URL.
Currently I have the following markup:
#Html.ActionLink("SomeSite", "http://subdomain.mydomain.com/SomeSite")
This markup produces:
http://localhost:58980/AccessInstance/http%3a/subdomain.mydomain.com/SomeSite
instead of :
http://subdomain.mydomain.com/SomeSite
What can I change in my markup to make this work as I expect?
You don't need to use #Html.ActionLink for that. Just use a plain A tag:
SomeSite
Html.ActionLink is specifically for generating links to actions defined in MVC controllers, in the same app. Since you're linking to an absolute URL, you don't need any of the functionality that Html.ActionLink provides.
Two ways :
1. update the database column with full link:
eg SQL:
update ProductTable set ProductLink='http://www.example.com/Product/Mobiles' where ID=123
In asp mvc view
View
2. Hardcode the http part and list from model
View
Hope helps someone.
While a ViewBag is overused and not the best choice most of the time this is something that I had done when inheriting someone else's mvc app to do a quick fix for a URL that I needed to redirect to with a specific dynamically changing querystring parameter
<a target="_parent" href="http://localhost:56332/services/#ViewBag.factory">View Service</a>
Using .NET Core 6
This seems to be the most correct answer:
Link
This will generate the following result:
As you can see at the bottom left corner of the window before clicking the link, the URL address was rendered as it is (NOTE: The cursor was recorded out of place for some reason, that's a ShareX problem, ignore it).
Than link will be directly saved as a nvarchar(750) type (probably any character like type will do the work). No changes to the original link were made before saving it or on reading:
You need to take into account your RouteConfiguration.
routes.MapRoute(
name: "Default",
url: "{controller}/{action}"
because you are specifying the action link as the entire link that you want to redirect.
I would recommend that you use the #rossipedia answer because you can make tricky things like putting a span inside the link
Here to display link that are clickable in index page
<td>
#Html.ActionLink(item.FileName, "../Uploads/Catalogue/"+item.FileName)
</td>
Let's say that I have a blog where each post can have several sections and comments and I'd like to use a hard-links to navigate and operate on this. There are several samples using some pseudo-code, of course they doesn't work, just demonstring my intends :)
Of course /blog.html#/posts/1 uses PostRoute, PostController etc and uses :post_id for finding object - that's obvoius.
How can I pass (and then access) additional params which doesn't change the controller but I can use them to navigation. ie /blog.html#/posts/1?section=123 should use the same route, controller and view as it was just Post, but I'd like to read the section and just navigate to section with #123
/blog.html#/posts/1/?comments=456 - actually should behave like section from point 1, but navigates to comment and optionally add some class to the container.
Other case: I'd like to go to section 123 AND additionally edit it with link like: /blog.html#/posts/1?section=123&action=edit. Now I'm using a button with an action like {{action editSection section}} and {{#if isEdit}} but I'd like to be able to reflect this in URL and also go to this state from URL (de facto my post can have several different modes not only preview/edit, therefore it should be accesible by the link).
I hope that cases makes sense, TBH I have no idea in which direction should I go. Tried with nested routes, but I'd like to avoid changing the controller. Also have no concept how to reflect the action in the URL...
I'm using Ember 1.1.2
You can use the model method of the route to handle such parameters, separate them from the model parameter and set the appropriate controller state.
Another approach would be to use nested routes that will render un-nested views(and controllers) - as explained towards the bottom here.
Is it possible to not using angualar routes, because if I defined an routes like:
app.config(function($routeProvider){
$routeProvider.when('/home')
})
my url will look like www.app.com/#home,
I dont want to change url, just www.app.com nice and clean, in this case how to defined template for defferent controller and how to load the template in ng-view, and how to pass url parameter?
any idea?
You cannot do that with the built-in routing mechanism because path is required for every route. However, you can use ui-router library in order to create URL-less states and navigate to them using either code or directive.
I created this plunker to demonstrate how to use ui-router to navigate among states without modifying URL.
This is a bit of a puzzle for me.
I need to capture the URI Query string passed to the Home page.
As a user travels to different pages on the web site, I have a partial view that needs that URI query string.
I need a dynamicly created link in the partial view, that equals the original call to the home page.
Example -
If the user goes to - http://www.mysite.com?mode=Joe , I need the dynamicly created link to equal - Http://www.mysite.com?mode=Joe
If the user goes to - http://www.mysite.com?mode=Tommy , I need the dynamicly created link to equal - Http://www.mysite.com?mode=Tommy
FYI - The partial view is used in the _Layout.cshtml file. the call inside - _Layout.cshtml looks like this -
#Html.Partial("MyPartial")
Thanks!
There are a number of ways to do this, but probably the simplest would be to save it to the session on your home page, and then access that session variable from your partial.
You will need to decide what to do if the session expires.
Another possible way would be to write it to a cookie on the home page request and then access the request cookie in your partial. Again, you'd need to decide on an approach for cookies disabled, or wiped out during browsing.
Alternatively, you could look at something like the approach being used in the link below to set a language across the site. Exact implementation would differ, but concept is the same:
Howto automatically add a specific value from current route to all generated links?
Even If the url is same can i go to different action using Html.RouteLink and Action Link.Like when i click on news link i will go to news details.The url of this page is http://localhost:1390/en-US/latestnews/125.Now if i select the ddl of language in the site header in this pagei need to
go to the home page of the site.The ddl (on change) will take the same url but this time it needs to go to action in the sane controller.
The URL will direct to the controller/action on the first routing entry that it matches regardless of how you generate it. I'm not sure exactly what you are trying to accomplish, but I suspect that what you need to do is use javascript to direct to a different url, perhaps generated with Html.RouteLink instead of Html.ActionLink based on the value of the drop down list when it's selected. If I'm misunderstanding what you are trying to do, please clarify.
