CheckedList (onItemClicked) - How do i know if item is(was) selected or not?

Example:

var checked = new AW.UI.CheckedList;
    checked.onItemClicked = function(event, i){
             // i is selected, will turn selected or what?
        }

In this case i is an item index. Might be easier using other events -

Individual item selection state - true/false

obj.onItemSelectedChanged = function(value, index){
alert(value + " " + index);
}

or array of all selected items

obj.onSelectedItemsChanged = function(values){
alert(values);
}

Nice, tkz.

Am I correct that onItemSelectedChanged fires twice for a AW.UI.Combo? The old value is held by <index> when <value> is false?

Not sure about combo, but with lists in general, yes, one item selection state changes from true to false (unselected) and another one from false to true (the one being selected) so onItemSelectedChanged event fires twice.

Also for each of them there is onItemSelectedChanging event which fires before change.

And also there is an array of selected items, which has its own change events - onSelectedItemsChanging/Changed.

Can you abort the change with onItemSelectedChanging() if you return 1, like with onCellValidating()?

I'll add that I've tried and it apparently doesn't work that (hoped for) way. In fact, onItemSelectedChanging() and onItemSelectedChanged() seem to both return the same index based on the true/false of the value argument. They only differ on the timeing of when they are called?

var feeCombo = new AW.UI.Combo();
feeCombo.setId("feeCombo");
feeCombo.setItemCount(myFeesVals.length);
feeCombo.setItemText(myFeesVals);
feeCombo.setItemValue(myFeesKeys);
feeCombo.defineItemProperty("color", myFeesClrs); 
feeCombo.getItemTemplate().setStyle("color", function(){
    if (this.getItemProperty("color") == "noshow")
        return "red";
    else
        return "black";
});
// make combo more <select>-like
feeCombo.getContent("box/text").setAttribute("readonly", true);
feeCombo.onControlEditStarted = function() {
    this.getContent("box/text").element().contentEditable = false;
};
feeCombo.onItemSelectedChanging = function(value, index) {
    if ( value ) {
        if( myFeesClrs[index] == "noshow" )
            return 1;
    }
}
