Is there an ASP.NET MVC HtmlHelper for image links?
The Html.RouteLink() HtmlHelper works great for text links. But what's the best way to link an image?
<a href="<%=Url.RouteUrl(...)%>"><img src="..." alt="..." /></a>
Here is mine, it`s the core function make some overloads
public static string ImageLink(this HtmlHelper htmlHelper, string imgSrc, string alt, string actionName, string controllerName, object routeValues, object htmlAttributes, object imgHtmlAttributes)
{
UrlHelper urlHelper = ((Controller)htmlHelper.ViewContext.Controller).Url;
string imgtag = htmlHelper.Image(imgSrc, alt,imgHtmlAttributes);
string url = urlHelper.Action(actionName, controllerName, routeValues);
TagBuilder imglink = new TagBuilder("a");
imglink.MergeAttribute("href", url);
imglink.InnerHtml =imgtag;
imglink.MergeAttributes(new RouteValueDictionary(htmlAttributes), true);
return imglink.ToString();
}
This is an updated version that I have from MiniScalope answer above. I'm using VS2010 and ASP.Net MVC 2 Preview
public static string ImageLink(this HtmlHelper htmlHelper, string imgSrc, string alt, string actionName, string controllerName, object routeValues, object htmlAttributes, object imgHtmlAttributes)
{
UrlHelper urlHelper = ((Controller)htmlHelper.ViewContext.Controller).Url;
TagBuilder imgTag = new TagBuilder("img");
imgTag.MergeAttribute("src", imgSrc);
imgTag.MergeAttributes((IDictionary<string, string>) imgHtmlAttributes,true);
string url = urlHelper.Action(actionName, controllerName, routeValues);
TagBuilder imglink = new TagBuilder("a");
imglink.MergeAttribute("href", url);
imglink.InnerHtml = imgTag.ToString();
imglink.MergeAttributes((IDictionary<string, string>)htmlAttributes, true);
return imglink.ToString();
}
<%= Html.ActionLink(Html.Image(imageUrl, imageAlt), actionName, controllerName) %>
could work, the image extension is from the futures assembly. Or make your own extention.
Create your own helper extension.
public static string Image(this HtmlHelper helper, string src, string alt)
{
TagBuilder tb = new TagBuilder("img");
tb.Attributes.Add("src", helper.Encode(src));
tb.Attributes.Add("alt", helper.Encode(alt));
return tb.ToString(TagRenderMode.SelfClosing);
}
