ASP.NET MVC Ajax.ActionLink with Image

今天研究Ajax.ActionLink之使用方法，但需以Image顯示Link之方式，
而ASP.NET MVC RC2並沒有支援，故Google一下，發現有人已遇到相同問題，
且有解法故將其記錄下來：

1. 實作一個ImageActionLinkHelper類別：

using System;

using System.Collections.Generic;

using System.Linq;

using System.Text;

using System.Web.Mvc;

using System.Web.Mvc.Html;

using System.Web.Mvc.Ajax;



namespace IPRO.Mvc.Html

{

    public static class ImageActionLinkHelper

    {

        public static string ImageActionLink(this AjaxHelper helper, string imageUrl, string altText, string actionName, object routeValues, AjaxOptions ajaxOptions)

        {

            var builder = new TagBuilder("img");

            builder.MergeAttribute("src", imageUrl);

            builder.MergeAttribute("alt", altText);

            var link = helper.ActionLink("[replaceme]", actionName, routeValues, ajaxOptions);

            return link.ToHtmlString().Replace("[replaceme]", builder.ToString(TagRenderMode.SelfClosing));

        }

    }

}

2.ASP.NET 頁面.aspx

<%= Ajax.ImageActionLink(Url.Content("~/Content/img/trashcan_icon.gif"), Resources.ContactPersonDelete, "Delete", new { Person_id = item.Person_id },new AjaxOptions { Confirm = "確認", HttpMethod = "Post", OnSuccess = "myReload" })%>
