MS Excel Type Filter in Flex 4

I implemented MS-Excel kind of flitering long time back. The post can be found at this post:

The main method for that was the following filter function.

public function commonFilter(item:Object):Boolean{

02	var deviceFilterSelected:Boolean = (deviceColumn.selectedItem != null && deviceColumn.selectedItem != "All")?true:false;

03	var severityFilterSelected:Boolean = (severityColumn.selectedItem !=null && severityColumn.selectedItem != "All")?true:false;

04	var stupidityFilterSelected:Boolean = (stupidityColumn.selectedItem !=null && stupidityColumn.selectedItem != "All")?true:false;

05

06

07	if(deviceFilterSelected){

08	if(item.device != deviceColumn.selectedItem)

09	return false;

10

}

11

12	if(severityFilterSelected){

13	if(item.severity != severityColumn.selectedItem)

14	return false;

15

}

16

17	if(stupidityFilterSelected){

18	if(item.stupidity != stupidityColumn.selectedItem)

19	return false;

20

}

21	/*Now return true*/

22	return true;

23

}
