Flex DataGrid: Show only rows which have specific value in one column

I have an ArrayCollection which is a dataProvider to the DataGrid. The ArrayCollection may look like that:

{Name: Bob; LikesIceCream:YES},
{Name: Carl; LikesIceCream:NO},
{Name: Ed; LikesIceCream:NO}

I want to have a checkbox, which would make the DataGrid show either all people when it is checked, or only those who have a property LikesIceCream:NO when it is not checked. How do I achieve that?

You can use filterFunction property of ArrayCollection.

Write your own function that will filter collection:

function myFilterFunction(item: Object): Boolean 
{
   var result: Boolean = true;
   if (!checkBox.selected)  
   {
      result = (item.LikesIceCream == "Yes");
   }
   return result;
}

Set collection filterFunction property

collection.filterFunction = myFilterFunction;

Refresh collection initially and after check box change

collection.refresh();
