Dynamic Map Service and Feature Layer

ChristopherJohnson1 — Wed, 30 Sep 2015 11:37:28 GMT

Good morning.

I have a JavaScript application that uses both a dynamic map service layer and a feature layer. if I render the map, with just the feature layer, everything displays fine. However, if I add the dynamic map service layer to the map, as well, the map is pushed down on the page. If I use CSS to modify the position of the map (using negative margins), the map is almost functional, but clicking on the map generates incorrect data -- if I click on Ohio, I will get the data for a State that is more South than Ohio. I assume that this is due to the re-positioning using CSS, as this behavior is absent when I just have the feature layer on the map. Any thoughts on any of this?

Thanks...Chris

Hi Christopher,

This sounds like this could possibly be a projection issue. Would you be able to post your code?

Hi, Jake. Both the DynamicMapServiceLayer and the FeatureLayer have the same projection, but they had different extents. I specified the extent and now the map appears correctly, without the gap at the top. Thanks for the hint!
