Similar to a Foreach, this component must be wrapped by
a Form. It provides the iteration of the Foreach but helps to avoid stale link
exceptions by recording the number of items in its source, as well as an encoding of
each value, as hidden fields in the form.
Parameters
- source
The source of objects to be iterated, and array or List of objects.
This is only accessed when the containing page is renderred, not when the
containing form is rewound.
- value
Used to update the current value on each iteration.
