  • MVC actionlink posting List of complex type

    - by Ying
    I have an actionlink that on click im passing a List of objects to a controller action. Example: View: Html.ActionLink("TestLink", "TestMethod", "Test", Model.SampleList, null) TestController: public ActionResult TestMethod(List sampleList) { return View(sampleList); } When I do this I get a null sampleList. I can pass a single complex object fine just not a collection of it. Do I need the correct routing for this? The reason I'm doing this is instead of passing an id and do a look up in the controller action, I just pass in the data.

  • MVC ActionLink omits action when action equals default route value

    - by rjygraham
    I have the following routes defined for my application: routes.MapRoute( "Referral", // Route name "{referralCode}", // URL with parameters new { controller = "Home", action = "Index" } // Parameter defaults ); routes.MapRoute( "Default", // Route name "{controller}/{action}", // URL with parameters new { controller = "Home", action = "Index" } // Parameter defaults ); And I'm trying to create an ActionLink to go on the Index action on my AdminController: @Html.ActionLink("admin", "Index", "Admin") However, when the view is executed the ActionLink renders as (Index action value is omitted): <a href="/Admin">admin</a> Normally this would be ok, but it's causing a collision with the "Referral" route. NOTE: If I instead use ActionLink to render a different action like "Default," the ActionLink renders correctly: <a href="/Admin/Default">admin</a> The fact that the "Default" action renders correctly leads me to believe the problem has to do with the default value specified for the route. Is there anyway to force ActionLink to render the "Index" action as well?

  • Possible to write an Extension Method for ASP.NET's Html.ActionLink() method?

    - by Pretzel
    Right now, I'm trying to work around an IE6/7 bug which requires the wrapping of the </a closing tag with this IE specific comment to make some drop-down menu work: <!--[if IE 7]><!--></a><!--<![endif]--> Unfortunately, I cannot inject this directly into my View page code like this: <%= Html.ActionLink("LinkName<!--[if IE 7]><!--></a><!--<![endif]-->","Action","Controller") %> As Html.ActionLink will do the safe thing and filter out the comment to prevent a Javascript injection attack. Ok, cool. I'm fine with that. Good design decision. What I'd like to do is write an Extension Method to this, but the process is eluding me as I haven't done this before. I thought this would work, but Intellisense doesn't seem to be picking up this Extension method that I've written. public static class MyLinkExtensions { public static string ActionLinkIE(this HtmlHelper htmlHelper, string linkText, string actionName, string controllerName) { return LinkExtensions.ActionLink(htmlHelper, linkText, actionName, controllerName). Replace(@"</a>", @"<!--[if IE 7]><!--></a><!--<![endif]-->"); } } Any suggestions?

  • Conditionally add htmlAttributes to ASP.NET MVC Html.ActionLink

    - by macca1
    I'm wondering if it's possible to conditionally add a parameter in a call to a method. For example, I am rendering a bunch of links (six total) for navigation in my Site.Master: <%= Html.ActionLink("About", "About", "Pages") %> | <%= Html.ActionLink("Contact", "Contact", "Pages") %> <%-- etc, etc. --%> I'd like to include a CSS class of "selected" for the link if it's on that page. So in my controller I'm returning this: ViewData.Add("CurrentPage", "About"); return View(); And then in the view I have an htmlAttributes dictionary: <% Dictionary<string,object> htmlAttributes = new Dictionary<string,object>(); htmlAttributes.Add("class","selected");%> Now my only question is how do I include the htmlAttributes for the proper ActionLink. I could do it this way for each link: <% htmlAttributes.Clear(); if (ViewData["CurrentPage"] == "Contact") htmlAttributes.Add("class","selected");%> <%= Html.ActionLink("Contact", "Contact", "Pages", htmlAttributes) %> But that seems a little repetitive. Is there some way to do something like this psuedo code: <%= Html.ActionLink("Contact", "Contact", "Pages", if(ViewData["CurrentPage"] == "Contact") { htmlAttributes }) %> That's obviously not valid syntax, but is there a correct way to do that? I'm open to any totally different suggestions for rendering these links. I'd like to stay with something like ActionLink that takes advantage of using my routes though instead of hard coding the tag.

  • Creating an Ajax.ActionLink that avoids all caching issues

    - by Richard Ev
    I am using an Ajax.ActionLink to display a partial view that shows a settings dialog (the modality of which is arranged using jQuery UI dialog). The issue I am running into is around browser caching. It is important that the user is never shown a cached settings dialog. In an attempt to achieve this I have written the following extension method that has the same method signature as the ActionLink method overload that I am using. /// <summary> /// Defines an AJAX ActionLink that effectively bypasses browser caching issues /// by adding an additional route value that contains a unique (actually DateTime.Now.Ticks) value. /// </summary> public static MvcHtmlString NonCachingActionLink(this AjaxHelper helper, string linkText, string actionName, string controllerName, System.Web.Routing.RouteValueDictionary routeValues, AjaxOptions ajaxOptions) { routeValues.Add("rnd", DateTime.Now.Ticks); return helper.ActionLink(linkText, actionName, controllerName, routeValues, ajaxOptions); } This works well between browser sessions (as the rnd route value gets re-calculated on page load), but not if the user is on the page, makes settings changes, saves them (which is done with another ajax call) and then re-displays the settings dialog. My next step is to look into creating my own ActionLink equivalent that re-calculates a random query string component as part of the onclick JavaScript event handler. Thoughts please.

  • Edit Html.ActionLink output string

    - by Aaron Salazar
    I'm trying to output the following HTML using Html.ActionLink: <a href="/About" class="read-more">Read More<span class="arrow">?</span></a> I'm getting it done by doing an ActionLink, which outputs an tag and then manipulating the string. <%= Html.ActionLink("[[replace]]", "Index", "About", null, new { @class = "read-more" }).ToHtmlString().Replace("[[replace]]", "Read More" + "<span class='arrow'>?</span>")%></p> It'd be good if I could put HTML directly into the ActionLink but there doesn't seem to be a way based on my internet searches. Sure, it works but it seems like a hack. Is there a better way to accomplish this?

  • Problems with MVC Ajax.ActionLink and returning a PartialView

    - by mwright
    I'm trying to implement a simple Ajax update using MVC and have run into an issue. My understanding of how to implement Ajax with MVC is to use an Ajax.ActionLink which allows the content to be updated based on user interaction. I have an Ajax.ActionLink that looks like the following: <%= Ajax.ActionLink("Call Ajax", "Ajax", new AjaxOptions{UpdateTargetId = "updateDiv"}) %> If, in the controller, I return a string it works fine. However, when returning a PartialView instead, nothing happens. I can step through and verify that the controller is "returning" the partial view but nothing shows up in what I'm calling the updateDiv. How can I go about determining what the problem is?

  • ASP.net MVC 3 adding arbitrary text to the end of an ActionLink

    - by infensus
    Hi I have a question about Html.ActionLink. Imagine: @Html.ActionLink(item.title, "Singlet", new { id = item.blog_id }) produces http://[url]/[controller]/Singlet/[id] But what if I want to suffix some more arbitrary data at the end? For example: http://[url]/[controller]/Singlet/[id]/#comments To jump to the comments div. I know I can just make the string myself with something like: @( new HtmlString(String.Format("<a href=\"Blog/Singlet/{0}/#comments\">link to comments</a>", item.blog_id)) ) But I am hoping there is a cleaner way, perhaps with ActionLink? Thanks

  • Passing a string in Html.ActionLink in MVC 2

    - by 109221793
    I have completed the MVC Music Store application, and now am making my own modifications for practice, and also to prepare me to do similar tasks in my job. What I have done, is create a view that displays the current list of users. I have done this as I want to be able to change the passwords of users should they forget them. Here is a snippet from my view: <% foreach (MembershipUser user in Model) { %> <tr> <td><%: Html.ActionLink(user.UserName, "changeUserPassword", "StoreManager", new { username = user.UserName }) %></td> <td><%: user.LastActivityDate %></td> <td><%: user.IsLockedOut %></td> </tr> <% }%> What I want to know, is it possible to pass the username through the actionlink as I have done above. I have registered the following route in the global.asax.cs file, however I am unsure if I have done it correctly: routes.MapRoute( "AdminPassword", //Route name "{controller}/{action}/{username}", //URL with parameters new { controller = "StoreManager", action = "changeUserPassword", username = UrlParameter.Optional }); Here is my GET action: public ActionResult changeUserPassword(string username) { ViewData["username"] = username; return View(); } I have debugged through the code to find that ViewData["username"] = username doesn't populate so it looks like either I have not registered the routes properly, or I simply cannot pass the username using the actionlink like I have. I'd be grateful if someone could point me in the right direction.

  • Attempting to update multiple partial views from a single Ajax.ActionLink

    - by mwright
    I have a a partial view which contains other partial views. I am trying to the main partial view ( "MainPartialView" ) from an Ajax.ActionLink in a partial view contained by the main partial view ( "DetailsView" ). Everything appears to be called just fine and I can step through and it executes all of the code on the pages. However, after that is all done it throws this error in a popup box in visual studio: htmlfile: Unknown runtime error This error puts the break point in the MicrosoftAjax.js file, Line 5, Col 83,632, Ch 83632. Any thoughts? Index Page: <script src="../../Scripts/MicrosoftAjax.js" type="text/javascript"></script> <script src="../../Scripts/MicrosoftMvcAjax.js" type="text/javascript"></script> <ul> <% foreach (DomainObject domainObject in Model) { %> <% Html.RenderPartial("MainPartialView", domainObject); %> <% } %> </ul> MainPartialView: <%@ Control Language="C#" Inherits="System.Web.Mvc.ViewUserControl<DomainObject>" %> <li> <div id="<%= Model.Id%>"> <%= Ajax.ActionLink("Details", "PartialViewAction", "PartialViewController", new { id = Model.Id, }, new AjaxOptions { UpdateTargetId ="UpdateTargetId" })%> <% Html.RenderPartial("Details", Model); %> <div id="Details"></div> </div> </li> Details: <%@ Control Language="C#" Inherits="System.Web.Mvc.ViewUserControl<DomainObject>" %> <% foreach ( var link in Model.Links) {%> <div> <div> <%= link.Name %> </div> <div> <%= Ajax.ActionLink("Submit this Action", "DoAction", "XTrademark", new { id = Model.TrademarkId, id2 = actionStateLink.ActionStateLinkId }, new AjaxOptions{ UpdateTargetId = Model.TrademarkId.ToString()} )%> </div> </div> <br /> <%} %>

  • MVC Ajax.ActionLink doesn't find POST method

    - by fearofawhackplanet
    I have a POST method declared in my controller: [AcceptVerbs(HttpVerbs.Post)] public ActionResult UpdateComments(int id, string comments) { // ... } and an ActionLink in my view: <%= Ajax.ActionLink("update", "UpdateComments", new { id = Model.Id, comments = "test" }, new AjaxOptions { HttpMethod="POST", OnFailure="alert('fail');", OnSuccess = "alert('success');" })%> I get a "not found" error when it tries to route this request. If I remove the POST restriction from the UpdateComments method in the controller, it works fine. What am I missing?

  • Create a T4MVC ActionLink with hash/pound sign)

    - by Dan Atkinson
    Is there a way to create a strongly typed T4MVC ActionLink with a hash in it? For example, here is the link I'd like to create: <a href="/Home/Index#food">Feed me</a> But there's no extension to the T4MVC object that can do this. <%= Html.ActionLink("Feed me", T4MVC.Home.Index()) %> So, what I end up having to do is create an action, and then embed it that way: <a href="<%= Url.Action(T4MVC.Home.Index()) %>"#food>Feed me</a> This isn't very desirable. Anyone have any ideas/suggestions? Thanks in advance

  • ASP.Net MVC Outbound Route Matching Problem When Using ActionLink

    - by Godders
    Hi there, Hoping for some help after reading into MVC routing and not coming up with the answer myself. I have the following routes registered: public static void RegisterRoutes(RouteCollection routes) { routes.IgnoreRoute("{resource}.axd/{*pathInfo}"); routes.MapRoute( null, "YourFeedback/Article/{resourceId}", new { controller = "YourFeedback", action = "Index", contentTypeId = new Guid(ConfigurationManager.AppSettings["ArticleLibraryId"]) }); routes.MapRoute( "Default", // Route name "{controller}/{action}/{id}", // URL with parameters new { controller = "Home", action = "Index", id = "" } // Parameter defaults ); } I have the following ActionLink in an aspx view: <%=Html.ActionLink("Your Feedback", "Article", "YourFeedback", new { resourceId = Model.ContentId.ResourceId }, new { @class = "yourFeedback" })%> My understanding of MVC routing is that this would render a anchor link with href of "/YourFeedback/Article/101" where 101 comes from Model.ContentId.ResourceId. Yet the anchor link href is rendered as "YourFeedback/Article/resourceId=101". Any ideas where I'm going wrong? Thanks in advance.

  • Pass Dictionary of routeValues to ActionLink

    - by Graham
    All, Getting to grips with ASP.NET MVC. So far, so good, but this one is a little nuts. I have a view model that contains a dictionary of attributes for a hyperlink, used like this: menu = model variable Html.ActionLink(Html.Encode(menu.Name), Html.Encode(menu.Action), Html.Encode(menu.Controller), menu.Attributes, null) The problem is the position of "menu.Attributes" expects an object in the form: new { Name = "Fred", Age=24 } From what I can tell, this anonymous object is actually converted to a dictionary via reflection anyway BUT you can't pass a dictionary to it in the first place!!! The Html generated for the link simply shows the dictionary type. How on earth do I get round this? The whole point is that its general and the controller can have set the menu.Attributes previously....

  • Ajax.ActionLink is not POSTing

    - by Dave Hanna
    I am trying to navigate to an MVC action by POSTing rather than GETting. (The action is a DELETE, and I don't want it reachable by an external link.) I am using a link in a grid generated by Ajax.ActionLink("Remove", "Delete", new { saID = Model.Said, id = e.id }, new AjaxOptions { HttpMethod = "POST", Confirm = "Are you sure you want to delete this item?" }) Which generates the following HTML: <a href="/Equipment/Delete/102424/229933" onclick="Sys.Mvc.AsyncHyperlink.handleClick(this, new Sys.UI.DomEvent(event), { insertionMode: Sys.Mvc.InsertionMode.replace, confirm: 'Are you sure you want to delete this item?', httpMethod: 'POST' });">Remove</a> My problem is that when I click on the link, I am reaching the Delete action via a GET rather than a POST, AND the Confirm dialog is not taking place. I have been googling this for several hours and just keep getting wrapped around the axle. What am I doing wrong?

  • html.actionlink with .net 4.0 renders empty links

    - by tmfkmoney
    This should hopefully be a simple configuration problem. When my application targets .Net 3.5 This code <%= Html.ActionLink("Forgot your password?","ForgotPassword") %> renders this: <a href="/Account/ForgotPassword">Forgot your password?</a> When my application targets .Net 4.0 The same code renders: <a href="">Forgot your password?</a> It's dropping the url part. backwards compatibility is supposedly enabled in my web.config. <pages controlRenderingCompatibilityVersion="3.5" clientIDMode="AutoID"> Ideas?

  • Asp.net MVC Calling ActionLink in Codebehind

    - by SSA
    I am new to asp.net and MVC, so please go easy on me. :) I have successfully made a small MVC application. There is a database that contains a table named "Entry" and I have made Controllers for this. Also I have a view for Details and list. This works fin. My problem is in my index page. (not the view Index, but the frontpage). There I dynamically build a TreeView as a menu, with some Categories. In this menu there is under the categories there is my Entries from the database. They show up fin. I insert the entries as a TreeNode what holds the entry id and so forth. What I want is: that the entries in my treeview work as a link to the Detail view of the Entry. So if I click on a entry in the TreeView it will show the Detail page of this Entry. But I can't make it work. How to I use the <%= Html.ActionLink() % in codebehind? Or is it this the wrong way? If calling the view or controller in codebehind is the wrong way to do it. Then how? Thanks in advance.

  • Configuring ASP.NET MVC ActionLink format with GoDaddy shared hosting

    - by Maxim Z.
    Background I have a GoDaddy shared Windows hosting plan and I'm running into a small issue with multiple domains. Many people have previously reported such an issue, but I am not interested in trying to resolve that problem altogether; all I want to accomplish is to change the format of my ActionLinks. Issue Let's say the domain that is mapped to my root hosting directory is example.com. GoDaddy forces mapping of other domains to subdirectories of the root. For example, my second domain, example1.com, is mapped to example.com/example1. I uploaded my ASP.NET MVC site to such a subdirectory, only to find that ActionLinks that are for navigation have the following format: http://example1.com/example1/Controller/Action In other words, even when I use the domain that is mapped to the subdirectory, the subdirectory is still used in the URL. However, I noticed that I can also access the same path by going to: http://example1.com/Controller/Action (leaving out the subdirectory) What I want to achieve I want to have my ActionLinks automatically drop the subdirectory, as it is not required. Is this possible without changing the ActionLinks into plain-old URLs?

  • How do you link to an action that takes an array as a parameter (RedirectToAction and/or ActionLink)

    - by Andrew
    I have an action defined like so: public ActionResult Foo(int[] bar) { ... } Url's like this will work as expected: .../Controller/Foo?bar=1&bar=3&bar=5 I have another action that does some work and then redirects to the Foo action above for some computed values of bar. Is there a simple way of specifying the route values with RedirectToAction or ActionLink so that the url's get generated like the above example? These don't seem to work: return RedirectToAction("Foo", new { bar = new[] { 1, 3, 5 } }); return RedirectToAction("Foo", new[] { 1, 3, 5 }); <%= Html.ActionLink("Foo", "Foo", new { bar = new[] { 1, 3, 5 } }) %> <%= Html.ActionLink("Foo", "Foo", new[] { 1, 3, 5 }) %> However, for a single item in the array, these do work: return RedirectToAction("Foo", new { bar = 1 }); <%= Html.ActionLink("Foo", "Foo", new { bar = 1 }) %> When setting bar to an array, it redirects to the following: .../Controller/Foo?a=System.Int32[] Finally, this is with ASP.NET MVC 2 RC. Thanks.

  • How do you set the title attribute of an ASP.NET MVC Html.ActionLink to the generated URL

    - by Keith Hill
    I would like users to be able to see the corresponding URL for an anchor tag generated by Html.ActionLink() when they hover over the link. This is done by setting the title attribute but where I'm stuck is figuring out how to get that value: @Html.ActionLink(@testrun.Name, "Download", "Trx", new { path = @testrun.TrxPath }, new { title = ??) How can I specify the URL that ActionLink is going to generate? I could hardcode something I guess but that violates DRY.
