Body
copied!<p>To further concrete what Tommy is saying, I wanted to include the ultimately called method that's being protected:</p> <pre><code>private static string GenerateLinkInternal(RequestContext requestContext, RouteCollection routeCollection, string linkText, string routeName, string actionName, string controllerName, string protocol, string hostName, string fragment, RouteValueDictionary routeValues, IDictionary<string, object> htmlAttributes, bool includeImplicitMvcValues) { string value = UrlHelper.GenerateUrl(routeName, actionName, controllerName, protocol, hostName, fragment, routeValues, routeCollection, requestContext, includeImplicitMvcValues); TagBuilder tagBuilder = new TagBuilder("a") { InnerHtml = (!string.IsNullOrEmpty(linkText)) ? HttpUtility.HtmlEncode(linkText) : string.Empty }; tagBuilder.MergeAttributes<string, object>(htmlAttributes); tagBuilder.MergeAttribute("href", value); return tagBuilder.ToString(TagRenderMode.Normal); } </code></pre> <p>so, since you're building a link, the outer method is throwing an exception because <strong>it wouldn't have any text to show on the screen.</strong> That code is shown below:</p> <pre><code>public static MvcHtmlString ActionLink(this HtmlHelper htmlHelper, string linkText, string actionName, string controllerName, RouteValueDictionary routeValues, IDictionary<string, object> htmlAttributes) { if (string.IsNullOrEmpty(linkText)) { throw new ArgumentException(MvcResources.Common_NullOrEmpty, "linkText"); } return MvcHtmlString.Create(HtmlHelper.GenerateLink(htmlHelper.ViewContext.RequestContext, htmlHelper.RouteCollection, linkText, null, actionName, controllerName, routeValues, htmlAttributes)); } </code></pre> <p>technically speaking that code doesn't <strong>have to be</strong> protected but it is as a <em>feature</em>.</p> <hr> <p>Here is a workaround for you, but you'll need to build your own <code>ActionLink</code> extension method like this and place it in a code file somewhere in the project:</p> <pre><code>using System; using System.Collections.Generic; using System.Web.Mvc.Resources; using System.Web.Routing; namespace System.Web.Mvc.Html { public static class MyLinkExtensions { public static MvcHtmlString ActionLink(this HtmlHelper htmlHelper, string linkText, string actionName, string controllerName, int identifier) { return htmlHelper.ActionLink(string.IsNullOrEmpty(linkText) ? "some default text" : linkText, actionName, controllerName, new { id = identifier }); } } } </code></pre> <p>and so now your markup looks like this:</p> <pre><code>@foreach (var row in Model) { <li>@Html.ActionLink(row.Name, "Action", "Controller", row.Id)</li> } </code></pre> <p>and you have encapsulated the turnary to determine the state of the <code>linkText</code> and yet still render your links in a single line.</p>
