Mohammed,

Manipulate the symbology of the layer in the MXD/MSD that the Map Service comes from.

Mohammed,

I can not actually say exactly what you need to do as I dont personally use the API's Legend component, but I would guess that you need to set the Legends map to null and back again to the map component after a layer is hidden or shown from the layerTOC. In the layerTOC look at the hideLayer and showLayer functions.

Mohammed,

Just update this function:

protected function application1_initializeHandler(event:FlexEvent):void
            {
                myLegend.layers = [ myDynamicService.visibleLayers ];
            }

MohammedIsmail

hi scheitlin

Its not working

it is diplaying all visible layers in the legend but

when i made any change in the TOC , legend is not getting updated

any other option to link TOC with legend

waiting for ur reply
Thanks

RobertScheitlin__GISP

Mohammed,

What do you mean by

when i made any change in the TOC

I guess I am just not understanding what you are attempting to do. The code change I suggested causes the legend to reflect the current visible layers, what else do you want?

MohammedIsmail
