I believe this is a case of Flash Builder not supporting this new type of ItemRenderer as it was a recently added feature.
Although, in the examples, I see this: <exp:MobileGridColumn headerText="S" dataField="status" width="30"> <exp:itemRenderer> <fx:Component> <exp:MobileGridBitmapCellRenderer iconFunction="{outerDocument.getMDPIStatusIcon}"/> </fx:Component> </exp:itemRenderer> </exp:MobileGridColumn> Have you tried this? A better option is to create it in pure AS3 like this: public class MyActionButtonPartRenderer extends Button implements IMobileGridCellRenderer { private var _data:Object; public function MyActionButtonPartRenderer() { super(); label = "Go"; height=30; addEventListener( MouseEvent.CLICK, onClick); } public function set styleProvider(value:IStyleClient):void { } public function get canSetContentWidth():Boolean { return true; } public function get canSetContentHeight():Boolean { return false; } public function set cssStyleName(value:String):void { } public function get data():Object { return _data; } public function set data(value:Object):void { _data = value; } private function onClick(event:MouseEvent):void { Alert.show("Click on: " + data.Name, "Action"); } } } Thanks, Om On Thu, Oct 20, 2016 at 4:42 PM, bilbosax <waspenc...@comcast.net> wrote: > If I try and create an inline itemRenderer, I am given the option to > create a > ns:MobileGridBitmapsCellRenderer, but if I try and create a tag in a > custom > itemRenderer that starts with ns:MobileGridBitmapsCellRenderer, it is not > accepted??? > > > > -- > View this message in context: http://apache-flex-users. > 2333346.n4.nabble.com/How-to-Create-A-MobilGrid- > ItemRenderer-tp13883p13884.html > Sent from the Apache Flex Users mailing list archive at Nabble.com. >
