You could make the CheckCellRenderer dispatch an event on the DataGrid,
i.e. inside your CheckCellRenderer:
<mx:CheckBox click="listOwner.dispatchEvent({type: 'cellClick', row:
getCellIndex().itemIndex})" />
This will make the DataGrid dispatch a "cellClick" event. To listen to
this event you'll need to add an event listener on the DataGrid
myGrid.addEventListener("cellClick", this);
The clicked row will be available in the event object passed to the
cellClick function, e.g.
function cellClick(event:Object):Void {
mx.controls.Alert.show("Row clicked: " + event.row);
}

Subject: [flexcoders] Re: 3 problems about datagrid ...
thanks for the reply...let me describe the problem i'm facing.
assume that the dategrid is a song list with several pages and i use a
CheckCellRenderer for a column.when user clicks the check box,the song
will add to his play list and remove it for another click.
i want to create a click handler in the mxml file,which functions to
watch all the check boxes,and when one of them is clicked,i can get the
number of the row.then append the selected song to the play list.
i used to add some code in the click handler in
CheckCellRenderer.as.like this:
if(check.checked)
listOwner._parent.addToPlayList(getCellIndex().itemIndex);
else
listOwner._parent.delFromPlayList(getCellIndex().itemIndex);
it seems strange though can work properly...
how can i do?
about problem 3:
to add a "..." is just what i want.but how to implement this cell
renderer?i've no idea...any prompt would be appreciated...
thanks a lot.
kevin
