问题 I'm trying to make a radiobuttonlist in razor syntax so far I have come up with this @foreach (var p in Model) { <div id="projectList" class="col-lg-5"> @Html.RadioButton("name", "1", false, new { onCLick = "ShowOption(this)", id = p.id.ToString() }) @Html.Label(p.id.ToString(), p.name) </div> } but the label isn't associated with the radiobutton. 回答1: Your foreach loop is not generating for attribute for the label (and if you removed new { id = p.id.ToString() } from the RadioButton method,

问题 We've just updated ASP.NET from Preview 3 to Preview 5 and we've run into a problem with the Html.Image HtmlHelper in our aspx pages. It seems that Html.Image has moved from System.Web.Mvc into Microsoft.Web.Mvc , and the only way we've found to access the helper now is to add an import statement to every .aspx page that uses it. All the other helpers can be accessed with using System.Web.Mvc; in the C# codebehind of a view master page, but this one seems to need an <@Import Namespace=

问题 We are trying to setup Sections of our layout to be Required but configurable based on the individual page. At the moment we do this with a Section. @section FloatingNav { <h1>@Model.Name <span class="release-year">@Model.AverageRating</span></h1> <ul class="sub-nav"> <li class="active"><a href="#episodes">Episodes</a></li> <li><a href="#episodes">Cast</a></li> <li>Reviews</li> <li>Related</li> </ul> } This requires you to setup this block in every new page but i wanted to make this process

问题 Trying to add a 'class' html attribute, but I think the keyword 'class' is causing issues. <%: Html.TextBox("name", "value", new {class: " required "})%> Is there a workaround? 回答1: Just prefix 'class' with an '@' as it's a reserved keyword. <%: Html.TextBox("name", "value", new { @class: " required "})%> If you need some background on the @ keyword, this is a good SO question to read. 来源： https://stackoverflow.com/questions/3038209/adding-a-css-class-with-html-textbox

问题 Here is my code. @using (Html.BeginForm()) { @Html.ValidationSummary() <fieldset> <legend>Registration Form</legend> <ol> <li> @Html.LabelFor(m => m.FirstName) @Html.TextBoxFor(m => m.FirstName) </li> </ol> </fieldset> } From the code above, the label and the textbox are on separate lines. I want to combine them to be on the same line so I can have something like... @Html.LablFor(m => m.FirstName): @Html.TextBoxFor(m => m.FirstName) Should end up looking like FirstName: _ __ _ __ _ Thanks in

问题 Is there an Html.NameFor feature, that gets the name html attribute for a model item? I'd like to use the following code in my Razor view: <input type="text" value="@Model.User.Email" name="@Html.NameFor(x => x.User.Email)"> 回答1: Html.NameFor is now included in MVC 4. 回答2: Yes, there is Html.NameFor method in the ASP.NET MVC Futures assembly. 回答3: If you just want to get the value for a name attribute that will work when binding the input back to your model you could use the ExpressionHelper

问题 Why should I use LabelFor instead of <label> ? eg. @Html.LabelFor(model => model.FirstName) @Html.DisplayFor(model => model.FirstName) vs <label for="FirstName">First Name</label> @Html.DisplayFor(model => model.FirstName) Further to the above, @p.s.w.g has covered the DRY aspect of this question. I would also like to know if it helps with localization. ie. Different labels based on the current language setting. 回答1: Well, if you've decorated your models with the DisplayNameAttribute like

问题 I’m stuck in a reference book by Steven Sanderson/Adum Freeman Pro ASP .Net MVC 3. I’ve made it up to page 185 where a HTML helper is to be used to return the numberer of pages in links. I found help on this site addressing my issue with this reference book, and walked through every step still having the same issues (link) MVC extension method error When I run the code in a browser I get this error: Compiler Error Message: CS1973: 'System.Web.Mvc.HtmlHelper' has no applicable method named

问题 We are in the process of upgrading an ASP.NET MVC 1.0 application to the 2.0 release and some of the code requires the use of LinkExtensions which require an HtmlHelper to render. While we know that some of the code doesn't follow the MVC model correctly and are in the process of recoding as needed, we need something to work so get the application to build. Here is the current syntax that we have that works under ASP.NET MVC 1.0: public static HtmlHelper GetHtmlHelper(ControllerContext

问题 I am trying to create my own HTML Helper which takes in an expression (similar to the built-in LabelFor<> helper. I have found examples to obtain the value of a property when the expression is similar to this: model => model.Forename However, in some of my models, I want to obtain properties in child elements, e.g. model => mode.Person.Forename In these examples, I cannot find anyway to (easily) obtain the value of Forename. Can anybody advise on how I should be getting this value. Thanks 回答1
