WmsServiceCatalog

WMS service catalog

This sample demonstrates how to connect to a WMS service and list available layers and sublayers. Layers are shown in a hierarchy. Selecting a group layer will recursively select all sublayers for display.

How to use the sample

• Open the sample. A hierarchical list of layers and sublayers will appear.
• Select a layer to enable it for display. If the layer has any children, the children will also be selected.

How it works

1. A WmsService is created and loaded.
2. A WmsService has a ServiceInfo property, which is a WmsServiceInfo
3. WmsServiceInfo has a WmsLayerInfo for each layer (excluding sublayers) in the LayerInfos collection
4. A method is called to recursively discover sublayers for each layer. Layers are wrapped in a view model and added to a list.

• The view model has a Select method which recursively selects or deselects itself and sublayers.
• The view model tracks the children and parent of each layer.
