Legend Tree Mode Organization w/ Graphics Layers

EthanGill

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:

1. Category 1
1. Layer 1
2. Layer 2
2. Category 2
1. Layer 1
2. Layer 2
3. Layer 3
3. Category 3
1. 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.
