ASP.NET MVC Templating

I have repetitious markup for elements, like:

<div class="box">
    <div class="top"></div>
    <div class="content">
      content goes here
    </div>
    <div class="bottom"></div>
</div>

Top and bottom are styled with css to include images for borders.

I could use JQuery to inject tags, but is there a better way to template controls in asp.net mvc?

Thank you

You definitely want to use an extension method to the HtmlHelper so that you can then use the notation:

<%=Html.Box("content string") %>

public static stringBox(
       this HtmlHelper html, 
       string Content)
  {
      var sb = new StringBuilder();

      sb.AppendLine("<div class=\"box\">");
      sb.AppendLine("    <div class=\"top\"></div>");
      sb.AppendLine("        <div class=\"content\">");
      sb.AppendLine(Content);
      sb.AppendLine("        </div>");
      sb.AppendLine("    <div class=\"bottom\"></div>");
      sb.AppendLine("</div>");

      return sb.ToString();
  }

There are probably a lot of ways around this, here's one:

Create a ViewUserControl (let's call it "box.ascx"):

<%@ Control Language="C#" Inherits="System.Web.Mvc.ViewUserControl<Action>" %>
<div class="box">
    <div class="top"></div>
    <div class="content">
        <% Model(); %>
    </div>
    <div class="bottom"></div>
</div>

In your aspx, wherever you need this block, call it like this:

<% Html.RenderPartial("box", Lambda.Action(() => { %>
here comes my content! <a href="http://www.google.com">Google!</a>
<% })); %>

Here's the Lambda helper class:

public static class Lambda {
    public static Action Action(Action a) {
        return a;
    }
}

If you don't use this little helper it will crash since it will try to cast the Action.

I just defined two extension methods to write the tags

  public static void BeginBox(this HtmlHelper htmlHelper)
  {
      StringBuilder box = new StringBuilder();

      box.AppendLine("<div class=\"box\">");
      box.AppendLine("    <div class=\"top\"></div>");
      box.AppendLine("        <div class=\"content\">");

      htmlHelper.ViewContext.HttpContext.Response.Write(box.ToString());
  }

  public static void EndBox(this HtmlHelper htmlHelper)
  {
      StringBuilder box = new StringBuilder();

      box.AppendLine("        </div>");
      box.AppendLine("    <div class=\"bottom\"></div>");
      box.AppendLine("</div>");

      htmlHelper.ViewContext.HttpContext.Response.Write(box.ToString());
  }

I guess this will do for now.

Why don't you use master pages? You can use master pages in MVC just like in ASP.Net

As far as I know there is no Built-In templating solution in asp.net mvc. But because the output is pure html it is very easy to do your own templating with just css and maybe a bit of JS.

Of course since everything in asp.net mvc is swappable you can replace the default view engine with one that supports templating.
