Interface ListItemIterator

All Superinterfaces:

java.io.Serializable

public interface ListItemIterator
extends java.io.Serializable

The ListItemIterator interface provides the ability to iterate through a list's values. This can be used to set properties on any of the controls used to render the list.

Example:

 var items = controls.listControl.list.items;
 while (items.next())
 {
   var val = items.listValue;
   if (val == "danger")
   { 
        controls.listItem1.backgroundColor = "red";
   }
 }
