Iain, out of curiousity I put your renderer code into a file named NumericStepperRenderer.mxml and it worked fine with the following sample app. There may be some problem in your datagrid declaration; a misnamed column perhaps?
<mx:Application xmlns:mx="http://www.macromedia.com/2003/mxml";> <mx:Script> <![CDATA[ var dataArray: Array = [ {label: "a", stepper: 1, fill:10}, {label: "b", stepper: 2, fill: 20}, {label: "c", stepper: 3, fill: 30} ]; ]]> </mx:Script> <mx:DataGrid dataProvider="{dataArray}"> <mx:columns> <mx:Array> <mx:DataGridColumn columnName="label" headerText="Label"/> <mx:DataGridColumn columnName="stepper" headerText="Stepper" cellRenderer="NumericStepperRenderer"/> </mx:Array> </mx:columns> </mx:DataGrid> </mx:Application> --- In [email protected], "digital_eyezed" <[EMAIL PROTECTED]> wrote: > > Thanks, > > I tried this, but the numericStepper just stops stepping. > > Any other ideas? > > CHeers, > > Iain > > New Renderer code: > > <mx:HBox horizontalAlign="center" width="100%" > xmlns:mx="http://www.macromedia.com/2003/mxml";> > <mx:Script> > <![CDATA[ > var labelData:Object; > var val; > var listOwner : MovieClip; > var getCellIndex : Function; > var getDataLabel : Function; > > function setValue(str:String, item:Object) { > if (item == undefined){ > visible = false; > return; > } > visible = true; > var s = item; > labelData = s; > val = labelData.stepper; > } > > function changeVal(){ > val = changed.value; > listOwner.editField(getCellIndex().itemIndex, getDataLabel(), val); > } > ]]> > </mx:Script> > <mx:NumericStepper id="changed" value="{val}" change="changeVal()" > maximum="{labelData.fill}"/> > </mx:HBox> > > --- In [email protected], "Doug Lowder" douglowder@ wrote: > > > > > > Hi Iain, > > > > You need to update the grid's data field in your change handler.
