Layer Order (with polygons) and click over a non-polygon element

BilGis — Fri, 11 Nov 2011 05:49:11 GMT

Hi.

Working with Flex API and ArcGIS Server 10.0, I'm creating a map with several layers: one of them is a polygon one.

When clicking on another layer (points or lines) and the the polygons are overlapped, it's impossible to select the values of the points or lines unless you hide/uncheck the polygons.

I've tried by changing the layer order, but without any success.

Any similar experience? Thank you very much.

Bill,

There is no real simple fix for this but there is a fix. You will have to add a event listener for graphicAdd when the layers graphics are added to the map and use the graphic objects autoMoveToTop=false for just the polygon layer.

Here is a sample that demos how to use the graphicAdd event:
