Flex Sample Viewer TOC order

DanielSmith — Mon, 27 Sep 2010 17:48:09 GMT

Hello,

1) Thanks to all who contribute on these forums. This resource is beyond valuable.

2) i need to reorder my layers in the TOC. Specifically i have tiled and dynamic services in my application (running AGS 9.3.1 and associated Flex lib version) and i need to mix and match their groupings based on year. Essentially we have 1 dynamic layer containing all of our vector data (3 years broken into group layers and ordered appropriately) and 6 tiled raster layers (2 for each year). i am looking for a way to put the year specific tiled services below the year specific group of vector data.

current TOC:
2009
|- point 2009
|- Line 2009
|- Poly 2009
2008
|- point 2008
|- Line 2008
|- Poly 2008
2009 Raster1
2009 Raster2
2008 Raster1
2008 Raster2

intended TOC:
2009
|- point 2009
|- Line 2009
|- Poly 2009
|- 2009 Raster 1
|- 2009 Raster 2
2008
   |- point 2008
   |- Line 2008
   |- Poly 2008
|-2008 Raster 1
|-2008 Raster 2

Help is greatly appreciated and returned with MVP bumps (assuming that functionality has been enabled on these new forums)...

Have a great day,
Daniel

Well i forgot/realized that i can manipulate the config.xml file to re order the layers. This is kinda of a workaround because I will have to generate year specific map services (not that big a deal but we are a small firm with limited resources).

This brings up the broader question though, How can/do you control the order of layers in the LiveMaps widget using Action script?

Thanks again,
Daniel

Daniel,

    You can do the same thing in ActionScript using the Map.reorderLayer method

Example
ActionScript code to move a layer to the bottom of all layers:

     myMap.reorderLayer("myGraphicsLayer", 0);

ActionScript code to move a layer to the top of all other layers:

     myMap.reorderLayer("myTiledLayer", myMap.layers.length);

Thank you very much Robert!

From my reading/understanding the map.reorderLayer() method reorders how map services are layered in the map and hence the TOC. But what do we do if we want to put a tiled service in between layers within a dynamic map service? Thanks again for your time.

Daniel,

That is not feasible, from what I know of the TOC as it is now.

huh...

Thanks for your help though Robert. Its always good to know what can and can't be done (easily).
