How to control draw order of AcMapLayer

[woehling]

Hi,

how can I programmatically control the draw order of my AcMapLayer layers?

I have a map with a "tree of layers" in it (multiple AcMapLayerGroup objects + multiple AcMapLayer objects).

Because the tree structure does not match the desired draw order of the layers, I want to change the draw order programmatically.

How can I do this?

I've already fumbled around a bit with the AcMapLayer.Group property.

I thought that

  1. setting the AcMapLayer.Group to null

  2. and then setting the AcMapLayer.Group to the group that I want

could solve the problem.

But the behavior ist quite strange -  is there any other way to set the group of a layer?

So this workaround (http://adndevblog.typepad.com/infrastructure/2012/08/get-and-set-acmaplayer-order-using-map-3d-platf... does not work for me, because I have to use groups.

Regards,

Markus

I've investigated the problem further and found a solution for me.

The main problem was that I used AcMapMap.AddLayersAsync(), which seems to cause some consequential errors (e.g. draw order of the layers is reversed)

I'm now using AcMapMap.GetLayers().Add(), and the behavior is "not so strange" after all.

I had to fumble around with AcMapLayer.SetOrder() to get the tree structure that I wanted.

Now everything works fine for me.
