Question

Is it possible to define a property to limit the number of elements which will appear in a mx:List ? I’ve read about setting the property rowCount, but I don’t see any effect.
Can a filter be applied to accomplish this? My intention was to avoid removing the items from the list/array collection, but simply “hide” them. Can this be done?

Answer 1

A different option is to use a new arraycollection and get your limited items from your big arraycollection :

//get first 10 elements
myArrayCollection = new ArrayCollection( myBigArrayCollection.toArray().slice(0,9) );

if you want to work with pagers, you could hold a counter where you keep track of what page the user is on, and get the next elements from you big array collection. example:

//this is just a (very) simple example
//page = integer (counter) for knowing which page the user is on
page = 0;
page_low = page*10;
page_high = page_low + 9;
myArrayCollection = new ArrayCollection( myBigArrayCollection.toArray().slice(page_low,page_high) );

(still using a filter is a more elegant solution)
