I have a form with a collection of checkbox's for a refine search function on my website.
I am trying to pass an array in a form GET but the URL looks like:
/search?filter=foo&filter=bar&filter=green
Is there a better way to pass this in MVC? Possible like
/search?filter=foo,bar,green
Thanks in advance.
There is now way you can change this URL. It is built by the browser.
You could change the URL by javascript before sending the request but the better way is to use the post redirect get pattern (PRG).
You first post to the controller and redirect to the url that you build in the controller. That way you have full controll over the URL.
EDIT
this is a sample
public ActionResult FilterResult()
{
RouteValueDictionary searchRoute = ControllerContext.RouteData.Values;
if (searchRoute["Filter"]==null)
{
searchRoute.Add("Filter","");
}
searchRoute["Filter"] = "filter1,filter2,filter3";
return RedirectToAction("Search", searchRoute);
}

I have a site entry controller that is used via a url generated by a single sign on manager. The SSO manager appends an identifying hash as an action parameter to the url of the system it is attempting to sign on to.
So the url being generated by the SSO manager looks like:
http://mysite/Entry/SingleSignOn?action=123456789ABCDEFG
I think I just need to set up a better route, but I haven't been able to get it to work yet. When I try to get the action from the url via standard MVC binding, it is giving me the name of the action, not the hash I need:
public ActionResult SingleSignOn(string action)
{
// action returns "SingleSignOn"
var querystring = Request.Url.Query; //returns "?action=123456789ABCDEFG"
return RedirectToAction("Index");
}
I know I can just split open the querystring, but would prefer not to if possible. It doesn't seem like a terribly complex problem, but I am just not finding the right route.
You can use Request.QueryString["action"] to explicitly get the parameter value from your request url.
public ActionResult SingleSignOn(string action)
{
var querystring = Request.QueryString["action"];
// Do something with querystring
return RedirectToAction("Index");
}
After a user has completed a form in MVC and the post action is underway, I am trying to redirect them back to another view within another model.
Eg. This form is a sub form of a main form and once the user has complete this sub form I want them to go back to the main form.
I thought the following might have done it, but it doesn't recognize the model...
//send back to edit page of the referral
return RedirectToAction("Edit", clientViewRecord.client);
Any suggestions are more that welcome...
You can't do it the way you are doing it. You are trying to pass a complex object in the url, and that just doesn't work. The best way to do this is using route values, but that requires you to build the route values specifically. Because of all this work, and the fact that the route values will be shown on the URL, you probably want this to be as simple a concise as possible. I suggest only passing the ID to the object, which you would then use to look up the object in the target action method.
For instance:
return RedirectToAction("Edit", new {id = clientViewRecord.client.ClientId});
The above assumes you at using standard MVC routing that takes an id parameter. and that client is a complex object and not just the id, in which case you'd just use id = clientViewRecord.client
A redirect is actually just a simple response. It has a status code (302 or 307 typically) and a Location response header that includes the URL you want to redirect to. Once the client receives this response, they will typically, then, request that URL via GET. Importantly, that's a brand new request, and the client will not include any data with it other than things that typically go along for the ride by default, like cookies.
Long and short, you cannot redirect with a "payload". That's just not how HTTP works. If you need the data after the redirect, you must persist it in some way, whether that be in a database or in the user's session.
If your intending to redirect to an action with the model. I could suggest using the tempdata to pass the model to the action method.
TempData["client"] = clientViewRecord.client;
return RedirectToAction("Edit");
public ActionResult Edit ()
{
if (TempData["client"] != null)
{
var client= TempData["client"] as Client ;
//to do...
}
}
This question is probably a dupe, but I couldn't find a similar one (not sure exactly what to search for).
Say I have a restful resource URL like this:
/my/items/6/edit
There is a form at this page which allows me to edit my #6 item. When I submit the form, it POSTS to /my/items/6, with a PUT X-HTTP-Method-Override header.
My question is, where should the server handler get the value "6" from? Should it get it from the URL? Or from the HTTP POST data (say the id was rendered as a hidden input field on the form)?
It seems to me like it should come from the URL. However this makes it a little more trouble to get it out. For example in .NET MVC, you might get it like this from a controller action method:
var id = int.Parse(ControllerContext.RouteData.Values["id"].ToString());
...which seems like more trouble than it's worth. However, if we get it out of the HTTP POST data, then technically you could post/put data for my item #6 to /my/items/7, and the server would still save the item data under id #6.
Are there any standard practices here?
Check this: http://www.codeproject.com/Articles/190267/Controllers-and-Routers-in-ASP-NET-MVC-3
I'm not a .net developer, though best practice in all platforms is to map your URI template to controller. Router must parse and prepare such information and pass it to your function/method.
It should definitely come from the URL. In ASP.NET MVC, if you had a route defined like this:
routes.MapRoute(
"Default",
"/my/{controller}/{id}/{action}",
new { controller = "items", action = "Index" }
);
You would be able to reference the ID from the ActionResult method signature, like this:
[HttpPut]
public ActionResult Index(int id, MyItemEditModel model)
{
// id would be 6 if the URL was /my/items/6/
// and the model need not contain the id
...
I'm trying to pass a list of URL's with Id attributes from a controller to a view.
I can pass a <a href=...> link back but I don't think writing a 'localhost' absolute path is a clean way of approaching this. I cant pass an ActionLink back as it returns the full string. Is ther a simple solution to this problem? Thanks in advance.
Using this overload of the UrlHelper.Action() method and Request object you can get a complete URL including the route parameters such as IDs and the actual hostname of the application.
string url = Url.Action("action", "controller",
new System.Web.Routing.RouteValueDictionary(new { id = id }),
"http", Request.Url.Host);
UrlHelper is available in the controller via its Url property.
You can then pass such URL into your view.
It is also possible to use UrlHelper directly inside your view to create URLs for controller actions. Depends if you really need to create them inside the controller.
Edit in response to comments:
Wherever you need to place the URLs, this "URL builder" you are looking for is still the UrlHelper. You just need to pass it (or the generated URLs) where you need it, being it inside the controller, view or custom helper.
To get the links inside the unsorted list HTML structure you mention, you need to put anchors inside the list items like this:
<ul>
<li>Link</li>
...
</ul>
Then again you just need to get the URLs from somewhere and that would be from UrlHelper.
Simple and easy.

the route id = the parameter that is going to be inserted into your method.
eg.
function Details(int id) {
//id has the value of my_var_id
}
In Asp.NET MVC, how do you make your controller return a view with a query string?
thanks
It might be better if you post what you are trying to accomplish. The simple answer is that you can't, the querystring is part of the request so if you wanted to do that you would need to redirect to your view with the querystring as part of the URL... but it sounds like you are perhaps trying to use the querystring to pass data to the view? If so you are much better off using ViewData.
This should get you started with returning views.
And this tutorial should show you how params can be passed into actions to generate specific results.
Use this
return RedirectToAction("AmendAbsence", new RouteValueDictionary (new { Controller ="Absence", Action="AmendAbsence", Id=id }));
Configure your Global.asmx appropriately
thanks
