Detailed Description

Features filtered from display remain available for query and analysis. Use display filter when only a subset of features needs to be visible while maintaining access to all features.

See also ScaleDisplayFilterDefinition::filters and ManualDisplayFilterDefinition::activeFilter.

Property Documentation

filterId : string

The identifier for this display filter (read-only).

Use a unique name to identify this display filter when used in a webmap as a ManualDisplayFilterDefinition::activeFilter.


name : string

A descriptive name for this display filter.


objectType : Enums.DisplayFilterType

The object type of this object (read-only).


whereClause : string

A SQL expression that defines which features are rendered.

The where clause string that is used as the whereClause should follow standard SQL syntax similar to what is discussed in the document SQL reference for query expressions used in ArcGIS.

A where clause that is not valid for the data may result in no features being drawn when this display filter is applied either by ManualDisplayFilterDefinition::activeFilter or by ScaleRangeDisplayFilter::maxScale. Check the layer's LayerViewState if there exists a Enums.LayerViewStatusWarning with an LayerViewState::error describing that the display filter's where clause is invalid.
