MVC :: Removing Automatically Appended Route Values From Html.ActionLink?
Aug 11, 2010
in my mvc2 application i have an action link like
[Code]....
docid is set to empty string because i want to clear ambient value of docid that is present in request context. i have gone through a lot of material on internet and even tried docid=String.Empty but it does not solve the problem and gives me url like /controller/action/id?docid=x. i also write a routeconstraint as suggested but it did not solve the problem either.clear those route values comming from request context with html.actionLink. i don't want to use html.routeLink

Global.asax route values
routes.MapRoute(
"Default", // Route name
"{controller}/{action}/{id}", // URL with parameters
new { controller = "Home", action = "Index", id = UrlParameter.Optional, filterDate = DateTime.Now.AddDays(-1), filterLevel = "INFO" } // Parameter defaults
);
Here's my actionlink
@Html.ActionLink(item.MachineName, "Machine", new { id = item.MachineName, filterLevel = "hello" }, null)
When the filterlevel is specified in the actionlink, it generates a url like this: [URL] Which is the same page as I am currently on. If I change the actionlink to use a property other than one that has a default value in the route table (yes, if I use filterDate it messes up too), it generates a link like this:..............

I have a post-only action that has a different route. In my form, I need to post to it, but also keep the querystring values I currently have.
Initial response: /my/first/path/?val1=hello
Needs to post to: /my/other/path/?val1=hello
It seems when I specify a route, it of course only returns the route and doesn't append the querystring values of my original page (for obvious reasons).Is it possible to cleanly append querystring values to my the action attribute of the form tag?

By default, links are created without the forward slash suffixed to the end. It is per our company standards to always have this trailing slash. Is it possible, via a configuration or whatever, to automatically have a forward slash whenever these methods are called?

I have a Microsoft MVC project with an action "Foo" whose view ("Foo.aspx") contains the lines:
<%= Html.ActionLink("mylinktext1", "bar") %>
<%= Html.ActionLink<MyController>(x => x.Bar(), "mylinktext2") %>
When I hit this from a web browser or load it from an AJAX call, it properly returns:
<a href="/bar">mylinktext1</a>
<a href="/Bar">mylinktext2</a>
But when I call the action from another view like this:
<% Html.RenderAction<MyController>(x => x.Foo()); %>
Then the links are rendered without targets.
<a href="">mylinktext1</a>
<a href="">mylinktext2</a>
Why would this be happening, and how do I work around it?

I have site culture in URLs like this:
routes.MapRoute(
"Default",
"{language}/{controller}/{action}/{id}",
languageDefaults,
languageConstraints)
And it works like a charm with a little help from custom MvcHttpHandler that sets current thread's UI culture on every request based on route value. My problem is how do I automatically add the language route value from current request to all outgoing links? E.g. when page /EN/Foo/Bar is requested, I would like this
<%=Html.ActionLink(
"example link",
MVC.Home.Index()) %>
To automatically generate the same result as this:
<%=Html.ActionLink(
"example link",
MVC.Home.Index()
.AddRouteValue(
"language",
this.ViewContext.RouteData.Values["language"]) %>
And of course the same for all other helpers like BeginForm() etc. In my current code base there are already > 1000 occasions where these helpers are used, and requiring .AddRouteValue every time is very fragile as some developer will forget to use it with 100 % certainty. I hope the only solution is not creating custom Html helpers for everything?

Im using the HTML.TreeView to render my code structure like this :
<%= Html.TreeView("CategoryTree",
Model.CategoryList,
l => l.ChildList,
l => l.Name + " / <a id="treeLnk" + l.Id + "" href="JavaScript: OpenAddDialog('" + l.Name + "', " + l.Id + ") " title="Lägg till" >Lägg till</a>" +
" / <a id="treeLnk" + l.Id + "" href="JavaScript: OpenChangeNameDialog('" + l.Name + "', " + l.Id + ") " title="Ändra namn" >Ändra namn</a>" +
" / <a id="treeLnk" + l.Id + "" href="JavaScript: OpenDeleteDialog('" + l.Name + "', " + l.Id + ") " title="Tabort" >Tabort</a>") %>
This work fine, but now I need to include a action that redirects to another controlleraction.
I have tried to ad a Html.ActionLink but this does not work?

Html.ActionLink("<span class="title">Retry</span><span class="arrow"></span>", "Login", "User")
If I execute above code in ASP.Net MVC 2, I get the following output on my screen:
How do I disable the escaping of the code, so my span is within the ActionLink, and not displayed as output?
I know this is expected behavior, to keep it safe, but I want it to interpret the HTML code I pass as a parameter.

How can i disable the html encoding?

I'm showing a small table with a list of usernames, and I want an ActionLink next to each username to Edit the user on another page.
[code]...
The usernames display correctly, just the link doesn't show up. I'm not sure why it wouldn't throw an error instead.What am I missing here?

Is it possible to use a condition inside an actionlink ?I would like to do this :

This will be used for some column sorting and if the current sort was asc the next sort has to be desc. The code above is not valid while compiling.

I was reading the ASP.NET MVC Best Practices article by Rashid, and got stuck in his description of creating UrlHelper extensions. Doing this is easy enough, and I've adopted the practice into all of my projects. I noticed, however, that Rashid used Url.Content to generate the url for the home page, and Url.RouteUrl for all the other urls. Why is this? What is the difference between the two?
The link to the blog post is here:
http://weblogs.asp.net/rashid/archive/2009/04/01/asp-net-mvc-best-practices-part-1.aspx
I've used Html.ActionLink in my Views, but I'm wondering what difference it would be if I used Url.RouteUrl instead. Does anyone have a good grasp of what makes these helpers different, and where they are best used?

I assume this link is correct
Html.ActionLink("Edit", "Edit" , new {Controller = "Item", id = item.Product_GUID});
the books tell me things i have read etc.i should render html as <a href="/Edit/Item?id=foo>Edit</a>
I am sending them to "another controller" to edit the item...
But this is not rendering the hyperlink in my browser, UGH....
this code is in a ascx page so i can call it with partialaction.
All i can think is that its not working because its 5am and i have been up since 9am yesterday..

I have a route (the first one listed) which looks like this:
routes.MapRoute(
"TopicRoute", // Route name
"forums/{forumSlug}/{topicSlug}", // URL with parameters
new { controller = "Forums", action = "Topic"} // Parameter defaults
);
I can browse to: /forums/my-forum/my-topic and the page loads fine. Yet I have a Html.ActionLink that looks like: @Html.ActionLink(item.Title, "Topic", new { forumSlug ="my-forum", topicSlug = "my-topic" }) And it won't generate the correct link syntax for me? It generates: <a href="">My Topic</a>

I'm having problems getting my CSS class to style an actionlink inside a html.partial. In building my test site, I've used the template beginning from ASP.NET and the standard login portion. My Index page works fine as the _Layout.cshtml does reference my css page. In _LogOnPartial, I have the following listed (there is more but this is what's important I believe):
else {
<text>
<ul style="display:inline;">;
<li style="list-style:none; display:inline;">
@Html.ActionLink("Sign In", "LogOn", "Account", null, new { @class = "signin" })
</li>
My CSS for "signin" is:
.signin {
text-decoration: none;
font-family: Helvetica, Arial, sans-serif;
font-weight: bold;
color: White;
}
When I look at the source for the page after debugging, it shows:
<a class="signin" href="/Account/LogOn">Sign In</a>
That looks right but it's not showing it correctly. The font isn't Helvetica and it is underlined and not white. I don't reference the css sheet in the LogOnPartial but I didn't think I'd have too.

I've never been able to understand why it is that some things are made in a particular way, and Html.ActionLink is one of these. In Global.asax, if I want to create a route, it has the format:
[Code]....
The order of the necessary parameters here is "name/controller/action/extra params". When using Html.ActionLink, the parameter order is "name/action/controller/extra params", which is much the same but with two of them switched around. To make things more confusing, the rendered html from the Html.ActionLink has the original order "controller/action/extra params" with the name inside of the anchor tag. Why do this? It's easy enough to memorize that the order is switched for absolutely no reason I can discerne, but why do it in the first place?
