What do u mean by "* datagrid column change.."* Which class does DGIconRender extend ?
Maybe what you need is to use inline item renderer and attach event listeners. You can also dispatch custom events as Munira said, if that is sufficient, go for it. If you need more control on specific events, then use inline item renderer. -Raj On Mon, Jan 24, 2011 at 3:53 PM, Munira Presswala <[email protected]>wrote: > hi, > > you can dispatch a custom event from the function onClickEvent and set it > bubbles true and then handle it in main application and addeventListener > should be called on data grid reference. > > On Thu, Jan 20, 2011 at 1:36 PM, Gautam Ram <[email protected]>wrote: > >> Hi.. >> >> <mx:DataGrid id="dgId" dataProvider="{ddStmt}"> >> <mx:columns> >> <mx:DataGridColumn dataField="name" headerText="Name" >> width="150"/> >> <mx:DataGridColumn id="typeId" dataField="type" >> itemRenderer="com.DGIconRender" headerText="file" width="200"/> >> >> </mx:columns> >> </mx:DataGrid> >> >> >> >> DGIconRender class .. >> -------------- >> >> override public function set data(value:Object):void >> { >> if(value != null) { >> super.data = value; >> } >> } >> >> >> public function onClickEvent():void{ >> Util.openDocument(data); >> } >> >> <mx:HBox width="100%" height="100%" verticalGap="0" horizontalGap="0" >> verticalAlign="middle" horizontalAlign="center"> >> <mx:HBox id="pdbox"> >> <mx:LinkButton id="testImage" rollOverColor="#FFFFFF" >> textRollOverColor="#000000" click="onClickEvent()"/> >> </mx:HBox> >> </mx:HBox> >> >> *My issue*: *select the dataFridcolumn using keyboard and invoke the >> onClickEvent() (In the ItemRendor) >> while datagrid column change.. while am trying to access that function >> using change() of datafrid >> am getting null object reference * >> >> Gautham >> >> >> >> >> On Thu, Jan 20, 2011 at 11:03 AM, Vikas Madan <[email protected]>wrote: >> >>> Gautham, I am not sure if I understood your problem properly.
