Question

In Asp.net MVC3 when you write below code , it generates wrapping html itself

 @using (Html.BeginForm()) {
                @Html.ValidationMessageFor(model => model.Text)
}

It generates codes in below format,

<form method="post" action="/Feeds">
   <!-- Fields Here -->
</form>

My question in @using (Html.BeginForm()) automatically adds <form> tag at beginning and end, how can i create something like that of my own.

I am looking for some thing like below

@using (Html.BeginMYCUSTOMDIV())
  {
        I am text inside div
  }

Expected Generated Output

<div class="customDivClass">
I am text inside div
</div>

Something along the lines:

public class MyDiv : IDisposable
{
    private readonly TextWriter _writer;
    public MyDiv(TextWriter writer)
    {
        _writer = writer;
    }

    public void Dispose()
    {
        _writer.WriteLine("</div>");
    }
}

public static class MyExtensions
{
    public static MyDiv BeginMYCUSTOMDIV(this HtmlHelper htmlHelper)
    {
        var div = new TagBuilder("div");
        div.AddCssClass("customDivClass");
        htmlHelper.ViewContext.Writer.WriteLine(div.ToString(TagRenderMode.StartTag));
        return new MyDiv(htmlHelper.ViewContext.Writer);
    }
}

and in the view:

@using (Html.BeginMYCUSTOMDIV())
{
    <span>Hello</span>
}

generates:

<div class="customDivClass">
    <span>Hello</span>
</div>
