Properties

	Name	Description
	Adapter	Gets the browser-specific adapter for the control. (Inherited from Control.)
	AdapterToUse	Gets or sets the adapter to use. Only valid if LivePersistence is set to true, otherwise persistence for selects is delegated to events and for save/delete is delegated to a UnitOfWork object.
	AdapterTypeName	Gets or sets the name of the DataAccessAdapter type.
	AllFieldsKeepEmptyStringAsValue	Gets / sets the allFieldsKeepEmptyStringAsValue value. Setting this parameter to true will disable FieldNamesKeepEmptyStringAsValue. Default: false. (Inherited from LLBLGenProDataSourceBase.)
	AllowDuplicates	Gets or sets if the DataSourceControl should allow duplicate instances in the data retrieved. If DataContainerType is set to EntityCollection, this setting is ignored, as entitycollection fetches always filter out duplicates. (Inherited from LLBLGenProDataSourceBase.)
	AppRelativeTemplateSourceDirectory	Gets or sets the application-relative virtual directory of the Page or UserControl object that contains this control. (Inherited from Control.)
	ASPNetCacheDuration	Gets or sets the duration in minutes the state data is stored in the ASP.NET cache in between page postbacks. Only valid if CacheLocation is set to ASPNetCache. (Inherited from LLBLGenProDataSourceBase.)

	PrefetchPathToUse	Gets or sets the PrefetchPath to use. Only valid if DataContainerType is set to EntityCollection.
	Refetch	Gets / sets the flag whether the control should refetch the data at the next select call from the bound control(s). Set this flag to true when you've persisted the embedded UnitOfWork object. This will also clear the unitofwork object on the next select.
	RenderingCompatibility	Gets a value that specifies the ASP.NET version that rendered HTML will be compatible with. (Inherited from Control.)
	SelectParameters	Parameters which are used to construct a PredicateExpression for live filtering. Hook up control properties or other parameters with the datasource so the datasource can filter based on values in other controls. (Inherited from LLBLGenProDataSourceBase.)

Events

	Name	Description
	DataBinding	Occurs when the server control binds to a data source. (Inherited from Control.)
	Disposed	Occurs when a server control is released from memory, which is the last stage of the server control lifecycle when an ASP.NET page is requested. (Inherited from Control.)
	ElementsFetched	Event which is raised when LivePersistence is set to true and the datasource control has performed a fetch of elements (be it entities, a typed list or a typedview). Use this event to be able to perform actions when a fetch takes place. The sender of the event is the datasource control so use that object to obtain the data fetched. (Inherited from LLBLGenProDataSourceBase.)
	EntityDeleted	Event which is raised when LivePersistence is set to true and an entity was deleted successfully. The deleted entity is part of the event args. (Inherited from LLBLGenProDataSourceBase.)
	EntityDeleting	Event which is raised when this datasource control is about to perform the delete action on an entity. If LivePersistence is set to false, this event is raised right before the entity to delete is added to the unitofwork(2) object. Cancelling this event will abort the delete action and the entity won't be inserted. The entity to delete is part of the event args. (Inherited from LLBLGenProDataSourceBase.)
	EntityInserted	Event which is raised when LivePersistence is set to true and an entity was inserted successfully. The inserted entity is part of the event args. (Inherited from LLBLGenProDataSourceBase.)
	EntityInserting	Event which is raised when this datasource control is about to perform the Insert action on an entity. If LivePersistence is set to false, this event is raised right before the entity to insert is added to the unitofwork(2) object. Cancelling this event will abort the insert action and the entity won't be inserted. The entity to insert is part of the event args. (Inherited from LLBLGenProDataSourceBase.)
	EntityUpdated	Event which is raised when LivePersistence is set to true and an entity was updated successfully. The updated entity is part of the event args. (Inherited from LLBLGenProDataSourceBase.)
	EntityUpdating	Event which is raised when this datasource control is about to perform the update action on an entity. If LivePersistence is set to false, this event is raised right before the entity to update is added to the unitofwork(2) object. Cancelling this event will abort the update action and the entity won't be inserted. The entity to update is part of the event args. (Inherited from LLBLGenProDataSourceBase.)
	Init	Occurs when the server control is initialized, which is the first step in its lifecycle. (Inherited from Control.)
	Load	Occurs when the server control is loaded into the Page object. (Inherited from Control.)
	PerformGetDbCount	Event which is raiseed when LivePersistence is set to false and a GetDbCount has to be performed.
	PerformSelect	Event which is raised when LivePersistence is set to false and a select has to be performed.
	PerformWork	Event which is raised when LivePersistence is set to false and an insert/update/delete has to be performed.
	PreRender	Occurs after the Control object is loaded but prior to rendering. (Inherited from Control.)
	Unload	Occurs when the server control is unloaded from memory. (Inherited from Control.)
