The conventions followed by asp.net mvc for model binding are volatile to my brain for some reason.
Here is a summary of the different ways to bind input fields to action parameters.
Assuming the following class:
public class Person
{
public string Name;
public string Email;
}
Binding a Custom type
<%= Html.TextBox("Name") %>
<%= Html.TextBox("Email") %>
Will bind to:
public ActionResult MyAction(Person myPerson)
{
// …
}
Binding a Custom type with parameter name prefix
<%= Html.TextBox("myPerson.Name") %>
<%= Html.TextBox("myPerson.Email") %>
Will bind to:
public ActionResult MyAction(Person myPerson)
{
//…
}
Binding a Custom type with a custom prefix
<%= Html.TextBox("myPrefix.Name") %>
<%= Html.TextBox("myPrefix.Email") %>
Will bind to:
public ActionResult MyAction([Bind(Prefix = "myPrefix")] Person myPerson)
{
// ...
}
Binding to Collections of Simple Types
<%= Html.TextBox("Name") %>
<%= Html.TextBox("Name") %>
<%= Html.TextBox("Name") %>
Will bind to:
public ActionResult MyAction(List<string> Name)
{
// …
}
Binding to Collections of Custom Types
<%= Html.TextBox("myPerson[0].Name") %>
<%= Html.TextBox("myPerson[0].Email") %>
<%= Html.TextBox("myPerson[1].Name") %>
<%= Html.TextBox("myPerson[1].Email") %>
Will bind to
public ActionResult MyAction(List<Person> myPerson)
{
//…
}
Binding to Dictionary of Custom Types
<%= Html.Hidden("myPerson[0].key", "keyOne") %>
<%= Html.TextBox("myPerson[0].value.Name") %>
<%= Html.Hidden("myPerson[1].key", "keyTwo") %>
<%= Html.TextBox("myPerson[1].value.Name") %>
Will bind to
public ActionResult MyAction(IDictionary<string, Person> myPerson)
{
// …
}
