Raw ActionLink linkText
I want to put a button as the text of an @ActionLink()
but I can't because it HTML-escapes my string... I found the @Html.Raw()
mechanism and have tried the @ActionLink().ToHtmlString()
but can't figure out how to put it together...
I found an article that describes building an extension for a similar purpose but it's ee开发者_开发知识库ky to go to that much trouble... there must be an easy way?
You could write a helper:
public static class HtmlExtensions
{
public static IHtmlString MyActionLink(
this HtmlHelper htmlHelper,
string linkText,
string action,
string controller,
object routeValues,
object htmlAttributes
)
{
var urlHelper = new UrlHelper(htmlHelper.ViewContext.RequestContext);
var anchor = new TagBuilder("a");
anchor.InnerHtml = linkText;
anchor.Attributes["href"] = urlHelper.Action(action, controller, routeValues);
anchor.MergeAttributes(new RouteValueDictionary(htmlAttributes));
return MvcHtmlString.Create(anchor.ToString());
}
}
and then use this helper:
@Html.MyActionLink(
"<span>Hello World</span>",
"foo",
"home",
new { id = "123" },
new { @class = "foo" }
)
which given default routes would produce:
<a class="foo" href="/home/foo/123"><span>Hello World</span></a>
If you want to create a custom action link that uses T4MVC library, You can write the below code:
public static System.Web.IHtmlString DtxActionLink(
this System.Web.Mvc.HtmlHelper html, string linkText,
System.Web.Mvc.ActionResult actionResult = null,
object htmlAttributes = null)
{
System.Web.Mvc.IT4MVCActionResult oT4MVCActionResult =
actionResult as System.Web.Mvc.IT4MVCActionResult;
if (oT4MVCActionResult == null)
{
return (null);
}
System.Web.Mvc.UrlHelper oUrlHelper =
new System.Web.Mvc.UrlHelper(html.ViewContext.RequestContext);
System.Web.Mvc.TagBuilder oTagBuilder =
new System.Web.Mvc.TagBuilder("a");
oTagBuilder.InnerHtml = linkText;
oTagBuilder.AddCssClass("btn btn-default");
oTagBuilder.Attributes["href"] = oUrlHelper.Action
(oT4MVCActionResult.Action,
oT4MVCActionResult.Controller,
oT4MVCActionResult.RouteValueDictionary);
oTagBuilder.MergeAttributes
(new System.Web.Routing.RouteValueDictionary(htmlAttributes));
return (html.Raw(oTagBuilder.ToString()));
}
