Legend Tree Mode Organization w/ Graphics Layers

Question

Hey everyone,

I'm currently building a wpf application which utilizes 5-20 graphics layers. These layers fit under three varying categories which I would like to reflect in the legend.

For Instance:* Category 1
* Layer 1
* Layer 2

* Category 2
* Layer 1
* Layer 2
* Layer 3

* Category 3
* Layer 1

I don't quite understand how to accomplish this in code behind. What property defines where in the legend tree structure a graphics layer resides?

Any help or suggestions on literature would be greatly appreciated!

Cheers,
Ethan

The legend reflects the organization of the layers in the map.

To get a hierarchy of layer, you have to organize your graphics layers into group layers.
Then you have to set your Legend.LayerItemsMode to "Tree".

The GroupLayers SDK sample demonstrates that.
