Public Property Gets whether the layer is expanded or collapsed on the TOC.  
Public Property Gets the layer's visibility state  
Public Property Gets a read only collection of legend groups. Check the LegendStatus property before accessing this collection.  
Public Property Gets the status of the layer's legend.  
Public Property Get the map which the MapMember belongs to. (Inherited from ArcGIS.Desktop.Mapping.MapMember)
Public Property Gets map layer type.  
Public Property Gets the duration of display cache for the layer.  
Public Property Gets the maximum distance (in meter) at which the layer is visible in a 3D scene or globe view.  
Public Property Gets the layer's maximum scale (representative fraction) at which the layer is visible in a 2D map view.  
Public Property Gets the minimum distance (in meter) at which the layer is visible in a 3D scene or globe view.

Public Property Gets whether the MapMember supports metadata (Inherited from ArcGIS.Desktop.Mapping.MapMember)
Public Property Gets the transparency value set to the layer. 100 being fully transparent and 0 means opaque.  
Public Property Gets the unique path of this MapMember. (Inherited from ArcGIS.Desktop.Mapping.MapMember)
