I have a data class that contains a number of fields:
public class Person
{
public int id { get; set }
public string Name { get; set; }
public double Rate { get; set; }
public int Type { get; set; }
}
If I understand Scott Hanselman's take on binding arrays of objects, I should be able to create a form view that renders HTML that looks like this:
<input name="Person[0].id" value="26" type="hidden" />
<input name="Person[0].Name" value="Tom Smith" type="text" />
<input name="Person[0].Rate" value="40.0" type="text" />
<select name="Person[0].Type">
<option selected="selected" value="1">Full Time</option>
<option value="2">Part Time</option>
</select>
<input name="Person[1].id" value="33" type="hidden" />
<input name="Person[1].Name" value="Fred Jones" type="text" />
<input name="Person[1].Rate" value="45.0" type="text" />
<select name="Person[1].Type">
<option value="1">Full Time</option>
<option selected="selected" value="2">Part Time</option>
</select>
I should then be able to capture this data in my controller with an action method that looks like this:
[AcceptVerbs(HttpVerbs.Post)]
public ActionResult People(Person[] array)
{
// Do stuff with array
}
But it doesn't work. The array variable is always null. I interpret this as the data binding is not working. But why?

<input name="Person[0].Rate" value="40.0" type="text" />
should be:
<input name="array[0].Rate" value="40.0" type="text" />

Your fields should be named array[0].id, array[0].Type, ...
They should have the name of the array instance, not the name of the Type inside the array.
Alternatively you could change the signature of the actioncontroller to: Person[] Person
You get the point :-)
