Properties

	Name	Description
	Connection	Current MetaConnection
	ConnectionGUID	The connection currently used for this data source
	Connections	List of MetaConnection
	DataSourceReferences	Defines other reference Data Sources loaded with the Data Source.
	Description	If true, this source is used as default when a new model is created in a report
	Error	Last error message
	ExternalConnections	If true, the connections are saved in a XML file located beside the Data Source file.
	GUID	The unique identifier (Inherited from RootComponent)
	IgnorePrePostError	If true, errors occuring during the Pre or Post SQL statements are ignored and the execution continues
	Information	Last information message
	InitScript	If set, the script is executed when a report is initialized for an execution. This may be useful to change dynamically components of the source (e.g. modifying connections, tables, columns, enums, etc.).
	IsDefault	If true, this source is used as default when a new model is created in a report
	IsNoSQL	If true, this source contains only tables built from dedicated Razor Scripts (one for the definition and one for the load). The a LINQ query will then be used to fill the models.
	IsSQL	If true, this source contains only a table built from a database. The SQL engine will be used to fill the models.
	MetaData	MetaData contained in the source
	MetaInfo	Meta information that can be used for any purpose
	Name	The name (Inherited from RootComponent)
	PostSQL	SQL Statement executed before the connection is closed and after the query is executed. The statement may contain Razor script if it starts with '@'.
	PreSQL	SQL Statement executed after the connection is open and before the query is executed. The statement may contain Razor script if it starts with '@'.
	Report	The current report (Inherited from ReportComponent)
