In webforms if i created a Public Property in code, i could assign a value through the template. As an example if i have a property called

string DefaultName {get; set;}

then on my template i could do something like

<macro.... DefaultName="Michael"..../macro>

How could i do the same for a MVC template if my code is something like

@Html.Partial("~/Views/Partials/Test/Index.cshtml", new Web.Models.TestForm())

I tried with this but it never worked

@Html.Partial("~/Views/Partials/Test/Index.cshtml", new Web.Models.TestForm() new {DefaultName="Michael"})

Thanks
