Display a subset of data?

Question

I have a data grid populated by an XMLList from an XML file.
Currently, it displays data from the entire file.
However, there is a node for each item in the list indicating
a category, e.g. "Fruits", Vegetables"
I want to have a toggle button bar with buttons "Fruits",
"Vegetables" that when clicked update the datagrid display to only
show records matching the term.
How is this done? The book I bought (Friends of Ed) only
showed the solution usinf ColdFusion, but I need to do it all in
Flex. Thanks.

Answer 1

I am not an expert but I have a set of radio buttons that
need to filter data in a grid and I use a filter function like
this;
----Where you load the datat associate a filter like
this------
acVendorDetail.filterFunction=grdVendorDetailFilter;
------ Here is the filter ---------
public function grdVendorDetailFilter(item:Object):Boolean
var result:Boolean=false;
switch (rbtnStatus.selectedValue.toString().toUpperCase())
case "ALL":
result=true;
break;
case "CLEARED":
if (item.CLEAR_DATE != null) result = true;
break;
case "UNCLEARED":
if (item.CLEAR_DATE == null) result = true;
break;
return result;
---- In the clickevent of the radio button do this ------
acVendorDetail.refresh();
That is all there is to it...
