Question

Does any one know how it’s possible to get in Flex 4 a value of the second item from Drop Down list, assuming I have 3 items listed there?
E.g.

• 5
• 4
• 9

I need 4

MyLable.text=myDDList.dataProvider.getItemAt(1).toString();

this one doesn’t work

Answer 1

Without knowing your dataProvider structure; it is impossible to give you a definite answer. This code will give you the object being displayed in the second item of the DropDownList:

var tempObject : Object = myDDList.dataProvider.getItemAt(1);

Using the default labelField, that object should have a field named label on it which will return your suggested value:

MyLable.text = tempObject['label'];

You can even make this slightly more flexible:

MyLable.text = tempObject[myDDList.labelField];

If you are using a labelFunction; you’ll have to run your object through the labelFunction procedure.

If you’re using custom objects in your dataProvider, you can use the approach in your own answer if you implement a toString() method in that object which returns the ‘4’ string.
