I fixed it with changing your onChange fn to;

private function onChange(evt:Event):void {
data.isSelected = selected;
}

so that it used the new checkbox state rather than assuming a state change. Hopefully that wan’t a dumb thing to do (worked at least).

I have used this Multi-Selected Checkbox, but finding it difficult to write a function which does Select-All or Deselects All.

Can anyone please supply/guide me with the code.

Appreciate the help.

I subclassed List (CheckList) and overrode the mouseDownHandler and mouseUpHandler functions, and changed the event.ctrlKey property when the mouse was over a checkbox (actually, I delegated the decision to the item renderer through mouseEventToItemRenderer(e); and a custom ICheckListRenderer interface.

I subclassed Checkbox (BlindCheckbox) and overrode clickHandler, leaving it blank (except for the stopImmedatePropogation command when disabled).

I added an event handler for each checkbox in the renderer (listData set function).
To get the parent list from the item renderer you use IDropInListItemRenderer and implement listData.

_parentList.addEventListener(ListEvent.CHANGE, function():void{
   chkSelected.selected = _parentList.isItemSelected(me.Data);
});
chkSelected.selected = _parentList.isItemSelected(me.Data);

Here’s how to translate mouse coordinates arbitrarily from any UI element event to local coordinates (Used by the item renderer to determine whether the checkbox was clicked. I give the user a larger click area).

var pt:Point = new Point(e.localX, e.localY);
 pt = DisplayObject(e.target).localToGlobal(pt);
pt = globalToLocal(pt);

I’ve tried modifying the selectedItems collection and overriding ctrlKey during the capture stage of the mouse events. Neither seem to work right.

Any ideas?

The way I accomplish that is to dispatch a custom DoFilter event each time a checkbox is checked/unchecked.

The DoFilter event triggers 2 things. First, it updates a list of active filters (unchecked check boxes). Second, it calls myDataGrid.dataProvider.refresh().

The refresh() call triggers the dataprovider’s sort() and filterFunction() functions.

You’ll need to define the filterFunction for the dataProvider such that it looks through the list of active filters and returns true/false for each item appropriately.
