How to show the required fields on the first access of a View?

Question

I am using MVC 2.0 and I wonder know how to show my required fields on the view on first acess.

For example.. I have a page that I can register a person and also I have my fields:

• Name;
• Age;
• City;
• Country;
• Phone;

But, just "Name" and "Phone" fields are requireds. I alread have the validation in my server side, but, I want that when somebody load the page, the page shows the required fields.

For example: Name [Put_text_here___________] *

I have on my pages:

<%= Html.TextBoxFor(model => model.soliInscricaoImobiliaria})%>

<%= Html.ValidationMessageFor(model => model.Name, "*") %>

How do I do that?

Best regards, Dan

This is not super user-friendly, and I'd look at putting it into a @helper block. But short of simply hard-coding an asterisk into the form...

@(ViewData.ModelMetadata.Properties.First(m => m.PropertyName == "Name").IsRequired ? "*" : "")
