/*
* This method sets up the Form and Field objects that
* are needed to dynamically generate html forms at runtime.
*
* Of course, there are other ways of going about defining your forms and their fields.
* I used a static class in this demo application for simplicity.
* In the real world, you could store your field definitions anywhere.
*
* For example, you could create a database table to store all
* of the data needed to create the form fields below.
* Some of your end users could have access to some kind of interface to create, update,
* or delete the form field definitions in the database.
* This described scenario was actually the inspiration for this project.
*
* There are 7 different Field types that can be used to construct the form:
* - TextBox (single line text input)
* - Textarea (multi line text input)
* - Checkbox
* - CheckboxList
* - RadioList
* - Select (Drop down lists and List boxes)
* - Literal (Any custom html at all. For display purposes only (no user input))
*
* Each Field type have a few things in common:
* - Title property: Used when storing end user's responses.
* - Prompt property: Question asked to the user for each field.
* - DisplayOrder property: The order that the field is displayed to the user.
* - Required property: Is the user required to complete the field?
* - InputHtmlAttributes: Allows the developer to set the input elements html attributes
*
* There are other properties and behaviors that some Field types do not share with each other.
* Take a look through the members of each Type to see what you can do.
* Much of each type's unique functionality is demonstrated below.
* Feel free to tinker around in this file, changing and adding fields.
* Don't forget to add newly created fields to the Form.
*
* The Form object is the object that contains all of your Field objects,
* triggers validation and rendering, and lets the developer access user responses.
* When constructing your form, you can use Form.AddFields() to get your Fields
* into the form (imagine that!).
*
* Check out
* /Controllers/HomeController.cs
* /Views/Home/Demo.aspx
* /Views/Home/Responses.aspx
* to learn how to use the Form object in your web application.
