IDataLayer Interface

Provides access to members that control the data source properties of a layer.

Product Availability

Available with ArcGIS Engine, ArcGIS Desktop, and ArcGIS Server.

Members

		Description
	Connect	Connects the layer to its data source. An optional name object can be specified to aid in repairing a lost connection.
	DataSourceName	Name of the data object for the layer.
	DataSourceSupported	Indicates if the specified data object name is supported by the layer.
	RelativeBase	Base path used when storing relative path names.
