Syntax

public sealed class AnnotationSublayer : ILayerContent, INotifyPropertyChanged

Remarks

You can get a ReadOnlyList of ILayerContent of the AnnotationSublayer from an AnnotationLayer using the SublayerContents property. AnnotationSublayer objects only exist as part of an AnnotationLayer object, populated when the AnnotationLayer is loaded. They cannot exist separately. Annotation sublayers offer finer control over your annotation, allowing the author to set different visual properties from the parent annotation layer. These visual properties include font, size, color, or different minimum and maximum scale ranges.

Properties

Name	Description
CanChangeVisibility	Gets a value indicating whether the sublayer's visibility can be changed.
DefinitionExpression	Gets the `Where` clause of the SQL expression that defines which annotation features from the feature table are selected into this Sublayer.
IsVisible	Gets or sets a value indicating whether the sublayer content is visible.
MaxScale	Gets the maximum scale at which to display the Sublayer.
MinScale	Gets the minimum scale at which to display the Sublayer.
Name	Gets the title of this Annotation sublayer.
Opacity	Gets the opacity with which to display the annotation text associated with this Sublayer.
ScaleSymbols	Gets a value indicating whether the annotation text scales with the MapView.
ShowInLegend	Gets or sets a value indicating whether the sublayer participates in the legend.
SublayerContents	Gets a read-only collection of ILayerContent for this sublayer.
SublayerId	Gets a non-negative number representing Id of the AnnotationSublayer within its AnnotationLayer.

Methods
