Laylist - Sublayers

ShaningYu — Tue, 03 Jul 2012 11:14:46 GMT

From the Laylist widget, how can it be enhanced to check on/off sublayers provided by each mapservice?

If you mean by default when the map first loads they are set in the MXD (whatever is showing visible in the MXD will be shown as checked in the layer list widget). I don't think there is a way to individually specify whether a layer/sublayer is checked on/off from within the widget itself.

You can set the "visiblelayers". See:

dpaddock: Thanks for your response. Could you provide some details that are specific?

"visiblelayers" should be a list of sublayer ids that you want on by default.

e.g.,

visiblelayers="4,7"

In the config.xml, I did like that:
            <layer label="Butler, PA - Vectors" type="tiled" visible="true"
                   url="http://10.74.44.31:6080/arcgis/rest/services/Butler/Butler_1/MapServer"
                   visiblelayers="2,3" />
But there is nothing different from that w/o visiblelayers="2,3".

"visiblelayers" only applies to to layer types dynamic, arcims, and wms.

You mean that philipp schnetzer's response is right - can't check on/off the layers defined in mapservices. Thanks.

You can't turn the layers on and off if you're using a cached map service unless it's a 10.1 server and you've enabled dynamic layers on the service.

You are right - Since they are cached map services, I can't turn on/off the layers. Thanks.
