MVC: set Default value in Html.TextboxFor Helper In Asp.Net MVC 2

Html.TextBoxFor in MVC 2 doesn't allow the setting of the value property using the object html attributes.
syntax - 
<%= Html.TextBoxFor(model => model.city, new { maxlength = "40" })%>

If you need to set a default value on a textbox field, you need to use the old 

syntax - 
<%= Html.TextBox("city", "New Delhi", new { maxlength = "40" })%>
