I am using Bootstrap ScrollSpy in MVC 5 application.
ScrollSpy works fine with plain html and jquery but I want to implement the same thing in MVC 5.
<li>About</li>
<li>Contact</li>
the above code works fine, but when I tried to implement the same thing in MVC I somehow get confused.
<li> #Html.ActionLink("About", null, null, null, new { #class = "hidden-xs" })</li>
<li> #Html.ActionLink("Contact", null,null, null, new { #class = "hidden-xs" })</li>
This is not working as expected as its trying to redirect to specified actionname or I may be doing something wrong.
Suggest something.
Requirement for Bootstrap scrollspy to work, the scrollable elements must match the ID of the links.
Here <li>Contact</li> should match div with id <div id="contact">
Using Mvc:
<li> #Html.ActionLink("Contact", "Index", "Home", null, null, "contact", null, null)</li>
<li> Contact</li>
Check difference between HTML.ActionLink vs Url.Action here.
So finally in server side both generates url with trailing slash before hash(#) as shown below:
Contact
And thus above link doesn't match div with id <div id="contact"> because of / before #
Solution Using Mvc:
Create Custom UrlHelper
Create a folder named Helpers and add a class named UrlExtensions finally add below code:
public static class UrlExtensions
{
public static string HashAnchorLinks(this UrlHelper url, string hashLinkName)
{
string hashAnchorLink = string.Format("#{0}", hashLinkName);
return hashAnchorLink;
}
}
In View:
#using YourProjectName.Helpers;
<li> About</li>
<li> Contact</li>
Note:
Best solution would be using plain html as you did before, instead of using server to return the hash link.

Your not passing the right parameters in into the ActionLink().
#Html.ActionLink("About", "Home", "About", new object { }, new { #class = "hidden-xs"})
#Html.ActionLink("Contact", "Home", "Contact", new object { }, new { #class = "hidden-xs"})
Here is a explanation of the function.
I have an action method signature of which is:
public ActionResult ViewContest(int id, int showNext){
//Some code here
}
In one of my views, I have this:
<a href="#Html.Action("ViewContest", "Home", new { id = Model.UserActivity.UserParticipation.CompetitionId, showNext = 1 })">
<img src="~/Image/RightArrow.png" style="float:right;width:40px;" />
</a>
When I run the program, the view passes the "id" value to the method correctly but the runtime throws an exception for showNext being null. Why is my showNext value not passing to the method? Any ideas?
You re using wrong helper. To generate url to ViewContest method of Home controller use:
#Url.Action("ViewContest", "Home", new { id = Model.UserActivity.UserParticipation.CompetitionId, showNext = 1 })
So eventually your code should look like:
<a href="#Url.Action("ViewContest", "Home", new { id = Model.UserActivity.UserParticipation.CompetitionId, showNext = 1 })">
<img src="~/Image/RightArrow.png" style="float:right;width:40px;" />
</a>
I have an action link inside a button that doesn't seem to be working:
<div style="position:absolute; top:0px; right:60px;">
<button class="btn-top btn-vitae shadow-bottom">
Help
</button>
</div>
The link is supposed to go to ActionResult Index in the HelpController:
public class HelpController : Controller
{
//
// GET: /Help/
public ActionResult Index()
{
return View();
}
}
Am I missing something?
if memory serves you need to swap them
<input type="button" class="btn-top btn-vitae shadow-bottom" />
Replace href="/Help" with #(Url.Action("Index", "Help"))
Using Url.Action you will be sure that the correct url is generated no matter what routing you're using.
your action link should include the controller name and action name like this
Help
or server side as suggested by #ssimeonov
One more way is to use Html.ActionLink (Instead of Anchor Tag) -
#Html.ActionLink("Help", "Index", "Home", null, new { target = "_blank" })
I've got a view that defines a form as
<% using (Html.BeginForm( "Update", "CcisCase", FormMethod.Post, new { id = "ccisEditForm" } ))
with a submit button:
In the RegisterRoutes method (in the HttpApplication-derived class in global.asax.cs), I've got:
routes.IgnoreRoute( "{resource}.axd/{*pathInfo}" );
routes.MapRoute(
"CcisCase",
"CcisCase/{action}/{cmDatabaseId}/{caseId}",
new { Controller = "CcisCase", Action = "CcisCaseEdit", caseId = "" } );
The url generated by MVC ends with "/Update" but there are no parameters. What am I doing wrong?
Thanks,
Bob
What parameters are you expecting to see? A post does not append parameters to the querystring, a FormMethod.Get would. And, that overload with the id is the collection of HTML attributes to render for the tag (which I'm assuming you knew, but just in case).
HTH.
Your route contains a parameter {caseId} but your BeginForm only defines an id value.
new {id = "cssEditForm"}
You need something like this to include the caseId value
using (Html.BeginForm( "Update", "CcisCase", FormMethod.Post, new { caseId = 1, id = "ccisEditForm" }
If your action isn't using the id="ccisEditForm" value then you can remove that for less code clutter.
I figured out what my problem was. I had to pass the existing route data as follows:
using (Html.BeginForm( "Update", "CcisCase", ViewContext.RouteData.Values, FormMethod.Post, new Dictionary<string, object> { { "id", "ccisEditForm" } } ))
Can anyone tell me how can I submit values to Controller using ActionLink and POST method?
I don't want to use buttons.
I guess it has something with jquery.
If you're using ASP MVC3 you could use an Ajax.ActionLink(), that allows you to specify a HTTP Method which you could set to "POST".
You can't use an ActionLink because that just renders an anchor <a> tag.
You can use a jQuery AJAX post.
Or just call the form's submit method with or without jQuery (which would be non-AJAX), perhaps in the onclick event of whatever control takes your fancy.
You can use jQuery to do a POST for all your buttons. Just give them the same CssClass name.
Use "return false;" at the end of your onclick javascript event if you want to do a server side RedirectToAction after the post otherwise just return the view.
Razor Code
#using (Html.BeginForm())
{
#Html.HiddenFor(model => model.ID)
#Html.ActionLink("Save", "SaveAction", "MainController", null, new { #class = "saveButton", onclick = "return false;" })
}
JQuery Code
$(document).ready(function () {
$('.saveButton').click(function () {
$(this).closest('form')[0].submit();
});
});
C#
[AcceptVerbs(HttpVerbs.Post)]
public ActionResult SaveAction(SaveViewModel model)
{
// Save code here...
return RedirectToAction("Index");
//return View(model);
}
#Aidos had the right answer just wanted to make it clear since it is hidden inside a comment on his post made by #CodingWithSpike.
#Ajax.ActionLink("Delete", "Delete", new { id = item.ApkModelId }, new AjaxOptions { HttpMethod = "POST" })
Here was an answer baked into the default ASP.NET MVC 5 project I believe that accomplishes my styling goals nicely in the UI. Form submit using pure javascript to some containing form.
#using (Html.BeginForm("Logout", "Account", FormMethod.Post, new { id = "logoutForm", #class = "navbar-right" }))
{
<a href="javascript:document.getElementById('logoutForm').submit()">
<span>Sign out</span>
</a>
}
The fully shown use case is a logout dropdown in the navigation bar of a web app.
#using (Html.BeginForm("Logout", "Account", FormMethod.Post, new { id = "logoutForm", #class = "navbar-right" }))
{
#Html.AntiForgeryToken()
<div class="dropdown">
<button type="button" class="btn btn-default dropdown-toggle" data-toggle="dropdown">
<span class="ma-nav-text ma-account-name">#User.Identity.Name</span>
<i class="material-icons md-36 text-inverse">person</i>
</button>
<ul class="dropdown-menu dropdown-menu-right ma-dropdown-tray">
<li>
<a href="javascript:document.getElementById('logoutForm').submit()">
<i class="material-icons">system_update_alt</i>
<span>Sign out</span>
</a>
</li>
</ul>
</div>
}
ActionLink will never fire post. It always trigger GET request.
Use the following the Call the Action Link:
<%= Html.ActionLink("Click Here" , "ActionName","ContorllerName" )%>
For submitting the form values use:
<% using (Html.BeginForm("CustomerSearchResults", "Customer"))
{ %>
<input type="text" id="Name" />
<input type="submit" class="dASButton" value="Submit" />
<% } %>
It will submit the Data to Customer Controller and CustomerSearchResults Action.
This is taken from the MVC sample project
#if (ViewBag.ShowRemoveButton)
{
using (Html.BeginForm("RemoveLogin", "Manage"))
{
#Html.AntiForgeryToken()
<div>
#Html.Hidden("company_name", account)
#Html.Hidden("returnUrl", Model.returnUrl)
<input type="submit" class="btn btn-default" value="Remove" title="Remove your email address from #account" />
</div>
}
}
Use this link inside Ajax.BeginForm
#Html.ActionLink(
"Save",
"SaveAction",
null,
null,
onclick = "$(this).parents('form').attr('action', $(this).attr('href'));$(this).parents('form').submit();return false;" })
;)
My Solution to this issue is a fairly simple one. I have a page that does a customer search one by the whole email and the other by a partial, the partial pulls and displays a list the list has an action link that points to a actionresult called GetByID and passes in the id
the GetByID pulls the data for the selected customer then returns
return View("Index", model);
which is the post method
This has been a difficult problem for me to solve. How can I build a dynamic link in razor and html that can call an action method and pass a value or values to a specific action method? I considered several options including a custom html helper. I just came up with a simple and elegant solution.
The view
#model IEnumerable<MyMvcApp.Models.Product>
#using (Html.BeginForm()) {
<table>
<thead>
<tr>
<td>Name</td>
<td>Price</td>
<td>Quantity</td>
</tr>
</thead>
#foreach (Product p in Model.Products)
{
<tr>
<td>#p.Name</td>
<td>#p.Price.ToString()</td>
<td>#p.Quantity.ToString()</td>
</tr>
}
</table>
}
The action method
public ViewResult Edit(Product prod)
{
ContextDB contextDB = new ContextDB();
Product product = contextDB.Products.Single(p => p.ProductID == prod.ProductId);
product = prod;
contextDB.SaveChanges();
return View("Edit");
}
The point here is that Url.Action does not care whether the action method is a GET or a POST. It will access either type of method. You can pass your data to the action method using
#Url.Action(string actionName, string controllerName, object routeValues)
the routeValues object. I have tried this and it works. No, you are not technically doing a post or submitting the form but if the routeValues object contains your data, it doesnt matter if its a post or a get. You can use a particular action method signature to select the right method.
I have done the same issue using following code:
#using (Html.BeginForm("Delete", "Admin"))
{
#Html.Hidden("ProductID", item.ProductID)
<input type="submit" value="Delete" />
}
This is my solution for the problem.
This is controller with 2 action methods
public class FeedbackController : Controller
{
public ActionResult Index()
{
var feedbacks =dataFromSomeSource.getData;
return View(feedbacks);
}
[System.Web.Mvc.HttpDelete]
[System.Web.Mvc.Authorize(Roles = "admin")]
public ActionResult Delete([FromBody]int id)
{
return RedirectToAction("Index");
}
}
In View I render construct following structure.
<html>
..
<script src="~/Scripts/bootbox.min.js"></script>
<script>
function confirmDelete(id) {
bootbox.confirm('#Resources.Resource.AreYouSure', function(result) {
if (result) {
document.getElementById('idField').value = id;
document.getElementById('myForm').submit();
}
}.bind(this));
}
</script>
#using (Html.BeginForm("Delete", "Feedback", FormMethod.Post, new { id = "myForm" }))
{
#Html.HttpMethodOverride(HttpVerbs.Delete)
#Html.Hidden("id",null,new{id="idField"})
foreach (var feedback in #Model)
{
if (User.Identity.IsAuthenticated && User.IsInRole("admin"))
{
#Html.ActionLink("Delete Item", "", new { id = #feedback.Id }, new { onClick = "confirmDelete("+feedback.Id+");return false;" })
}
}
...
</html>
Point of interest in Razor View:
JavaScript function confirmDelete(id) which is called when the link generated with #Html.ActionLink is clicked;
confirmDelete() function required id of item being clicked. This item is passed from onClick handler confirmDelete("+feedback.Id+");return false; Pay attention handler returns false to prevent default action - which is get request to target. OnClick event for buttons could be attached with jQuery for all buttons in the list as alternative (probably it will be even better, as it will be less text in the HTML page and data could be passed via data- attribute).
Form has id=myForm, in order to find it in confirmDelete().
Form includes #Html.HttpMethodOverride(HttpVerbs.Delete) in order to use the HttpDelete verb, as action marked with the HttpDeleteAttribute.
In the JS function I do use action confirmation (with help of external plugin, but standard confirm works fine too. Don't forget to use bind() in call back or var that=this (whatever you prefer).
Form has a hidden element with id='idField' and name='id'. So before the form is submitted after confirmation (result==true), the value of the hidden element is set to value passed argument and browser will submit data to controller like this:
Request URL:http://localhost:38874/Feedback/Delete
Request Method:POST Status Code:302 Found
Response Headers
Location:/Feedback
Host:localhost:38874
Form Data X-HTTP-Method-Override:DELETE id:5
As you see it is POST request with X-HTTP-Method-Override:DELETE and data in body set to "id:5". Response has 302 code which redirect to Index action, by this you refresh your screen after delete.
I would recommend staying pure to REST principles and using an HTTP delete for your deletes. Unfortunately HTML Specs only has HTTP Get & Post. A tag only can a HTTP Get. A form tag can either do a HTTP Get or Post. Fortunately if you use ajax you can do a HTTP Delete and this is what i recommend. See the following post for details: Http Deletes
Calling $.post() won't work as it is Ajax based. So a hybrid method needs to be used for this purpose.
Following is the solution which is working for me.
Steps:
1. Create URL for href which calls the a method with url and parameter
2. Call normal POST using JavaScript method
Solution:
In .cshtml:
View
Note: the anonymous method should be wrapped in (....)()
i.e.
(function() {
//code...
})();
postGo is defined as below in JavaScript.
Rest are simple..
#Url.Action("View") creates url for the call
{ 'id': #receipt.ReceiptId } creates parameters as object which is in-turn converted to POST fields in postGo method. This can be any parameter as you require
In JavaScript:
(function ($) {
$.extend({
getGo: function (url, params) {
document.location = url + '?' + $.param(params);
},
postGo: function (url, params) {
var $form = $("<form>")
.attr("method", "post")
.attr("action", url);
$.each(params, function (name, value) {
$("<input type='hidden'>")
.attr("name", name)
.attr("value", value)
.appendTo($form);
});
$form.appendTo("body");
$form.submit();
}
});
})(jQuery);
Reference URLs which I have used for postGo
Non-ajax GET/POST using jQuery (plugin?)
http://nuonical.com/jquery-postgo-plugin/
jQuery.post() will work if you have custom data. If you want to post existing form, it's easier to use ajaxSubmit().
And you don't have to setup this code in the ActionLink itself, since you can attach link handler in the document.ready() event (which is a preferred method anyway), for example using $(function(){ ... }) jQuery trick.
Came across this needing to POST from a Search (Index) page to the Result page. I did not need as much as #Vitaliy stated but it pointed me in the right direction. All I had to do was this:
#using (Html.BeginForm("Result", "Search", FormMethod.Post)) {
<div class="row">
<div class="col-md-4">
<div class="field">Search Term:</div>
<input id="k" name="k" type="text" placeholder="Search" />
</div>
</div>
<br />
<div class="row">
<div class="col-md-12">
<button type="submit" class="btn btn-default">Search</button>
</div>
</div>
}
My Controller had the following signature method:
[HttpPost]
public async Task<ActionResult> Result(string k)
