No need to use the HtmlHelper functions always and everywhere if they don't fit your need. They're just supposed to make your life easier, not harder. Use good ole HTML here:
<label id="id_for_label"></label>

If you want to keep using HtmlHelper functions you can always create your own extension methods.
For example:
public static class LabelHelper
{
private static string HtmlAttributes(object htmlAttributes)
{
var builder = new StringBuilder();
foreach (PropertyDescriptor descriptor in
TypeDescriptor.GetProperties(htmlAttributes))
{
builder.AppendFormat(" {0}=\"{1}\" ", descriptor.Name,
descriptor.GetValue(htmlAttributes));
}
return builder.ToString();
}
public static MvcHtmlString MyLabel(this HtmlHelper htmlHelper,
string labelText, object htmlAttributes)
{
var attributes = HtmlAttributes(htmlAttributes);
return MvcHtmlString.Create(
String.Format("<label for=\"{0}\" {1}>{0}</label",
labelText, attributes.Trim()));
}
}
Then you can add a label to a view in the following manner:
<%: Html.MyLabel("Hello, World!", new { @id = "myLabel" })%>
The generated HTML is:
<label for="Hello, World!" id="myLabel">Hello, World!</label>
For MVC 3 such a helper function is already available:
