Set drawing order of overlapping symbols

Joachim_EckboJuell — Fri, 25 Jun 2010 10:07:27 GMT

Hi,

I have a map service with overlapping points. And I have four different symbols (different size) in a UniqueValueRenderer. I need to make sure the largest one is "at the bottom" and the smallest one on top. How can I do this?

I have tried setting the Canvas.ZIndex on the Grid inside the esri:MarkerSymbol.ControlTemplate, with no luck...

Thanks 🙂

Nobody? Am I thinking completely wrong? Morten? 🙂

Thank you.

But it wasn't in my plan to loop through all the graphics in the FeatureLayer. I load everything OnDemand, so that will be heavy.

No other way?

No sorry. The problem with zindex is that it only works among elements within the same level in the UI tree. Setting it inside the control template means it's in a different level in the tree.
