html-helper

Just wondering what the difference is between these two and what the benefit for one or the other of them would be when I build my table in my HtmlHelper HtmlTable table = new HtmlTable(); and: TagBuilder table = new TagBuilder("table"); This is more or less the same as this question, Why use TagBuilder instead of StringBuilder? but I'm wondering more specifically about the difference between these two . The main difference is that HtmlTable provides typed and correctly named properties for all the valid HTML attributes of the <table> element (e.g. Width , Height , CellSpacing , etc). It also

Can somebody please suggest how I could write a Unit Test with Moq for following HtmlHelper method? public static HtmlTagBase GenerateTag<T>(this HtmlHelper htmlHelper , object elementData , object attributes) where T : HtmlTagBase { return (T)Activator.CreateInstance(typeof(T) , htmlHelper.ViewContext , elementData , attributes); } which you would use as follows (please note the using statement - this is causing me confusion): <%--Model is a type of ShareClass--%> <% using (Html.GenerateTag<DivTag>(Model)) { %> My Div <% } %> using this method, if you specify T as type DivTag , where

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 context) { return new HtmlHelper(new ViewContext(context, new WebFormView("HtmlHelperView"), new

You can provide alternate templates for individual types, but is it possible to override the template that wraps the label, field and validation up. Change: <div class="editor-label"><label for="Content">Content</label></div> <div class="editor-field"><input class="text-box single-line" id="Content" name="Content" type="text" value="" /> </div> To: <div class="field"> <label for="Content">Content</label> <input class="text-box single-line" id="Content" name="Content" type="text" value="" /> </div> Rich You can write an Object.ascx template and perform your own logic. 来源： https://stackoverflow

Is there in mvc any opportunity to read a name which will be assigned to html control? For example I use this code: <div> @Html.LabelFor(x => x.Name) @Html.TextBoxFor(x => x.Name) @Html.ValidationMessageFor(x => x.Name) @Html.HiddenFor(x => x.Id) <div> I want to display here a TextBox name </div> </div> And I want to get a name of input name. This code is fragment of partial view. Name of element looks like children[1].Name archil @Html.ViewContext.ViewData.TemplateInfo.GetFullHtmlFieldName("Name") Or you can use extension method for generic HtmlHelper to use this with Lambda Expressions

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 If you are using the same pattern that the LabelFor<> method uses, then the expression will always be a

I'm building an ASP.Net MVC website. Rather than have everything in one project, I've decided to separate the Web, Model and Controller out into different projects in the same solution, that reference each-other. The referencing goes like this: Web ---[references]---> Controller ---[references]---> Model Now I wanted to add 2 custom methods to the HtmlHelper class - they're called "IncludeScript" and "IncludeStyle". They each take a single string parameter, and generate a script or link tag respectively. I've created an extender class, according to documentation on the web, and written the two

I want to write an HtmlHelper to render an ActionLink with pre-set values, eg. <%=Html.PageLink("Page 1", "page-slug");%> where PageLink is a function that calls ActionLink with a known Action and Controller, eg. "Index" and "Page". Since HtmlHelper and UrlHelper do not exist inside a Controller or class, how do I get the relative URL to an action from inside a class? Update: Given the additional three years of accrued experience I have now, here's my advice: just use Html.ActionLink("My Link", new { controller = "Page", slug = "page-slug" }) or better yet, <a href="@Url.Action("ViewPage", new
