FeatureLayer Constructor(String,FeatureDataset)
See Also Example

ESRI.ArcGIS.ADF.IMS.Carto.Layer Namespace > FeatureLayer Class > FeatureLayer Constructor : FeatureLayer Constructor(String,FeatureDataset)

Visual Basic (Declaration)

Visual Basic (Usage)

C#

id: ID of the constructed FeatureLayer. This value must be unique if the constructed layer is to be added to a LayerCollection.

dataset: Dataset of the constructed FeatureLayer.

Constructs a FeatureLayer object.

Syntax

Visual Basic (Declaration)
Public Function New( _ ByVal id As String, _ ByVal dataset As FeatureDataset _ )

Visual Basic (Usage)	Copy Code
`Dim id As String Dim dataset As FeatureDataset Dim instance As FeatureLayer(id, dataset)`

C#
public FeatureLayer( string id, FeatureDataset dataset )

Parameters

id: ID of the constructed FeatureLayer. This value must be unique if the constructed layer is to be added to a LayerCollection.
dataset: Dataset of the constructed FeatureLayer.

Example

The following example creates a new FeatureLayer using a new workspace and data set. It sets a renderer for the new layer, then adds the layer to the map.

Remarks

This method enables creation of a dynamic layers, which are new map layers based on spatial data not currently used in the map service. To add a new layer not yet in the map service, you must define the FeatureDataset, which specifies the name of the data layer. In the FeatureDataset you must also define the workspace, which can be an existing workspace in the map service (NamedWorkspace) or a new workspace (SdeWorkspace or ShapeWorkspace).

The layer ID can be any combination of alpha and numeric characters.

Dynamic layers are not supported with ArcMap image services.
