How do I give a name to a form in ASP.NET MVC using Html.BeginForm()? I want only the name, not the action or controller name because I want to post it through Javascript. I think it should be something like Html.BeginForm(id = "frm").
I tried the following:
Html.BeginForm(null,null,new{id="frm",name="frm})
Html.BeginForm(new{#id="frm",#name="frm})
But the above code produces output like this:
<form action="/Main/Index/Id?name=Id" method="post">
Html.BeginForm(null, null, FormMethod.Get, new { name = "frm", id = "frm" })
You'll need to catch the form submit with your JavaScript
Using MVC2, this is what worked for me:
<% using (Html.BeginForm("Index", "Home", null, FormMethod.Post, new {#id = "myForm", #name = "myForm"})) {%>
#HTML.BeginForm("Target-ViewName where you want to post the page","Controller Name",new {#name="Name of the Form", id="ID of the Form"})
{ //form here
}
Taken from this answer: How to pass in ID with Html.BeginForm()?
Can you not just do:
Html.BeginForm(new {#id="Id", #name="Id"});
It can pay to search SO for answers as I've found many things I want to ask have already been encountered.

Because I wanted to assign an id to a form element my code was #using (Html.BeginForm(null, null, FormMethod.Post, new { id = "indexform"}))
This resulted in markup <form action="/cgi-bin?action=Index&controller=Home" id="indexform" method="post" style="position: relative;">
My HomeController ActionResult Index was completely bypassed.
Notice the '/cgi-bin'. This might be the problem and I think the culprit may be parameter 'FormMethod.Post' but I could not enter null there.
(BTW I worked around the id requirement by using jQuery var form = $("#btnShowProperty").closest("form");)
I did quite a bit of Googling on this with no luck.
The problem is you're passing null for the action and controller in the first two arguments. Instead, pass the name of your action and controller and it will work.
Example, if your action is "Index" and your controller is "Home", then use:
#using (Html.BeginForm("Index", "Home", FormMethod.Post, new { id = "indexform"})) {
...
}
The problem is mixing web pages and mvc especially using MapPageRoute AND MapRoute in Route.config. See full answer #Url.Action(“Action”, “Controller”) returns “/cgi-bin?action=Action&controller=Controller”
I have a modal which I will be using extensively on many different pages and hence I thought putting it in a partial view was appropriate. Within the modal is a form but I'm just getting a 'can't find action on controller error' whenever I try submit the form.
#using (Html.BeginForm("AddPlayerSignup", "SignupSheet", new {id = Model.Id, slug = Model.Slug}))
{
#Html.DropDownList("Member", Model.SignupSheet.GroupMembers, new {label = "Members"})
#Html.Hidden("SignupSheetId", Model.SignupSheet.Id)
#Html.Hidden("ModalId", Model.ModalId)
#Html.SubmitButton("Add", true, new {#class = "btn btn-primary"})
}
The weird thing is it's not even saying it can't find addplayersignup on signupsheetcontroller, it's saying it cant find list on ladder which is the source of the partial view.
Is posting forms from a partial view not supported or something?
It looks like you forgot to add a form method,...
#using (Html.BeginForm("AddPlayerSignup", "SignupSheet",FormMethod.Post ,new {id = Model.Id, slug = Model.Slug}))
That should do the trick
My url looks like this:
customer/login?ReturnUrl=home
In the login view, I have used this pattern of code which works fine.
#using(Html.BeginForm())
{
...
}
This magically generates following html
<form action="customer/login?ReturnUrl=home" method="post">
But now, I need to add an attribute (e.g., data-id="something") in the form. How can I do that? If I don't have any query string, I know I can do something like this:
#using(Html.BeginForm(action, controller, FormMethod.Post,
new { data_id="something" }))
But don't know how to add querystring which should be in html:
<form action="customer/login?ReturnUrl=home" method="post" data-id="something">
I thought about using <form> directly but don't know how to specify querystring which is variable. And I have no idea how to achieve it with Html.BeginForm. Any tip would be appreciated.
RESOLUTION:
For now, I used <form> with following hint How to get current url value in View. The resulting view looks like
<form action="#Request.Url.PathAndQuery" data-id="something" method="POST">
But it would be nice to have an overloaded method of BeginForm for this.
Here's The way that worked for me
Html.BeginForm("Profile", "Partner", routeValues: new {id=Partner.partner_id},method:FormMethod.Post)
It was almost like there was a problem with overloading the method, but by specifying what things are, it seems to work fine...
To create a RouteValueDictionary from the querystring:
RouteValueDictionary queryStringDictionary = new RouteValueDictionary(Request.QueryString.AllKeys.ToDictionary(key => key, key => (object)Request.QueryString[key]));
Then you can use it with Html.BeginForm:
Html.BeginForm(null, null, queryStringDictionary, FormMethod.Post, new Dictionary<string, object> { { "autocomplete", "off" } })
I guess this doesn't directly answer the question, but why not just use a plain old form tag?
<form action='customer/login?ReturnUrl=#Request.QueryString["ReturnUrl"]' method="post" data-id="something">
Alternatively, you can create a custom HtmlHelperExtension that renders a form with path and querystring. In this HtmlHelperExtension you can iterate through your querystring values and populate the routeValueDictionary which you then pass to a Html.BeginForm constructor.
If you don't want something so extensible you can just use the overloaded constructor of Html.BeginForm using
#Html.BeginForm("login", "customer", new {ReturnUrl = #Request.QueryString["ReturnUrl"]},FormMethod.Post, new {data-id="something"});
using Reflector to look at the code,
BeginForm() will pass directly the rawUrl over to the final Form.
Any other overloads on BeginForm will go through a helper utility which will strip the query string.
This works for me :
#using (Html.BeginForm("index", "Photos", routeValues: new { user = pUser, album = pAlbum, }, method: FormMethod.Get))
Explicit route values and method is what is required...
Just incase you wanted to add other attributes as well. use below code
#using (Html.BeginForm("actionName", "controllerName", routeValues: new { lang = "en" }, method:FormMethod.Post, htmlAttributes: new { #class= "my-form", enctype = "multipart/form-data" }))
Try #using(Html.BeginForm(null, null, FormMethod.Post, new { data_id="something" }))
It should use the default logic to construct the url, just as if you used BeginForm()
(never tried that though in such case, but I believe it should work)
I am having following action link:
<%= Html.ActionLink("Check this", "Edit", "test",
new { id = id }, new { style = "display:block" })%>
How do I include data=name as query string. Some thing like this:
link?data=name
4th parameter of Html.ActionLink can have any number of properties:
<%= Html.ActionLink("Check this", "Edit", "test",
new { id = id, data=name }, new { style = "display:block" })%>
These properties are inserted into URL based on routing, but if the property name cannot be matched into any route it is added as URL GET parameter.
So if you have standard route {controller}/{action}/{id}, you will get the URL:
test/Edit/[id]?data=[name]
from the above code.
Pass Query String By this way
#Html.ActionLink("Delete Record", "Home", "Delete", new { id=Id},null)
By above code you will get the url like(Suppose Id=1): /Home/Delete/1
and if you want to add more parameters to query string then:
#Html.ActionLink("Delete Record", "Home", "Delete", new { id=Id, Name=name},null)
By above code you will get the url like(Suppose Id=1 and Name=India) :
/Home/Delete/1?Name=India
I got tired of banging my head against a wall with the html.actionlink. Works great when you just want to route it against straightforward routing calls, but absolutely refuses to cooperate when you want to add a simple querystring at the end.
I don't an ID at then end, I want to be able to add some kind of actual Querystring with the "?".
So anywhere I needed a Querystring I switched to using the url.action inside the anchor tag.
<a href='#url.action("Action","route")?Parameter=Value' >Text for Link Name</a>
At least it works and I can stop getting headaches over something that should have been a very simple task. Someone needs to get their heads out of their butts and make the ActionLink work properly for Querystrings in the MVC routing.
I know this is kind of old question but.
In case the below code doesn't generate the <a href="/?param=value" />.
<%= Html.ActionLink("Text", "Action", "Controller", new { param=value }, null)%>
I would advice checking whether you action has at least one [Route] attribute (I used [Route("/")] for example).
Hope it helps.
I have the following ActionLink in my view
<%= Html.ActionLink("LinkText", "Action", "Controller"); %>
and it creates the following URL http://mywebsite.com/Controller/Action
Say I add an ID at the end like so: http://mywebsite.com/Controller/Action/53 and navigate to the page. On this page I have the markup I specified above. Now when I look at the URL it creates it looks like this:
http://mywebsite.com/Controller/Action/53 (notice the addition of the ID)
But I want it to remove the ID and look like it did originally, like this http://mywebsite.com/Controller/Action (notice no ID here)
Any ideas how I can fix this? I don't want to use hard coded URLs since my controller/actions may change.
The solution is to specify my own route values (the third parameter below)
<%= Html.ActionLink("LinkText", "Action", "Controller",
new { id=string.Empty }, null) %>
It sounds like you need to register a second "Action Only" route and use Html.RouteLink(). First register a route like this in you application start up:
routes.MapRoute("ActionOnly", "{controller}/{action}",
new { controller = "Home", action = "Index" } );
Then instead of ActionLink to create those links use:
Html.RouteLink("About","ActionOnly")
The problem is the built in methods take input from the URL you are currently on as well as what you supply. You could try this:
<%= Html.ActionLink("LinkText", "Action", "Controller", new { id = ""}) %>
That should manually wipe the id parameter.
Don't know why, but it didn't work for me (maybe because of Mvc2 RC). Created urlhelper method =>
public static string
WithoutRouteValues(this UrlHelper helper, ActionResult action,params string[] routeValues)
{
var rv = helper.RequestContext.RouteData.Values;
var ignoredValues = rv.Where(x=>routeValues.Any(z => z == x.Key)).ToList();
foreach (var ignoredValue in ignoredValues)
rv.Remove(ignoredValue.Key);
var res = helper.Action(action);
foreach (var ignoredValue in ignoredValues)
rv.Add(ignoredValue.Key, ignoredValue.Value);
return res;
}
If you either don't know what values need to be explicitly overridden or you just want to avoid the extra list of parameters you can use an extension method like the below.
View
The implementation details are in this blog post
I explicitly set the action name as "Action/". Seems a little like a hack but it's a quick fix.
#Html.ActionLink("Link Name", "Action/", "Controller")
Another way is to use ActionLink(HtmlHelper, String, String, RouteValueDictionary) overload, then there are no need to put null in the last parameter
<%= Html.ActionLink("Details", "Details", "Product", new RouteValueDictionary(new { id=item.ID })) %>
The overloads of Html.ActionLink are changed on the later versions of MVC. On MVC 5 and above. This is how to do this:
#Html.ActionLink("LinkText", "Action", "Controller", new { id = "" }, null)
Note I passed "" for id parameter and null for HTMLATTRIBUTES.
I needed my menu links to be dynamic. Rather than implement a lot of extra code and routing for every single page I simple dispensed with the HTML helper.
#item.MenuItemName
