List/DataGrid don't use click. They use mouseDown/mouseUp. You can try blocking those events.

I have some application-wide strategies in mind, and I have also seen how I can prevent tab switching in a tab navigator by registering a capture-phase click listener and calling stopImmediatePropagation and preventDefault. But the same strategy didn't work on a DataGrid, where the grid selection is used as a form of navigation: <mx:DataGrid id="roleList" creationComplete="onGridCreationComplete(event)" private function onGridCreationComplete(event:Event):void { myGrid.addEventListener(MouseEvent.CLICK, onClickGrid, true, 10); } private function onClickGrid(event:Event):void { // alert goes here event.stopImmediatePropagation(); event.preventDefault(); } As a workaround I could handle the change event and restore the previous selection but it would be better to conditionally suppress the selection. I've seen the post on Alex's blog, but am hoping for something listener-based. Thanks.
