ArcGIS.Desktop.Mapping Namespace / MapView Class / Range Property

In This Topic
    Range Property (MapView)
    In This Topic
    Gets or sets the range extent visible in the map view.
    Syntax
    public RangeExtent Range {get; set;}
    Public Property Range As RangeExtent
    Remarks
    This property is null when there are no layers with an active range in the map. When the Range property is not null, but both the Min and Max properties of the RangeExtent are null this means the map view is showing all values. This is equivalent to disabling range in the map view. Setting this property to null when there are layers with an active range in the map will set both the min and max properties of the RangeExtent to null.
