Properties
  NameDescription
Protected propertyAdapter
Gets the browser-specific adapter for the control.
(Inherited from Control.)
Public propertyAllFieldsKeepEmptyStringAsValue
Gets / sets the allFieldsKeepEmptyStringAsValue value. Setting this parameter to true will disable FieldNamesKeepEmptyStringAsValue. Default: false.
Public propertyAllowDuplicates
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.
Public propertyAppRelativeTemplateSourceDirectory
Gets or sets the application-relative virtual directory of the Page or UserControl object that contains this control.
(Inherited from Control.)
Public propertyASPNetCacheDuration
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.
Public propertyBindingContainer
Gets the control that contains this control's data binding.
(Inherited from Control.)
Public propertyCacheLocation
Gets or sets the location where to store loaded data. Default is Viewstate.

(Inherited from Control.)
Public propertyEnablePaging
Gets or sets whether Paging is enabled on this control. Default is false.

Events
  NameDescription
Public eventDataBinding
Occurs when the server control binds to a data source.
(Inherited from Control.)
Public eventDisposed
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.)
Public eventElementsFetched
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.
Public eventEntityDeleted
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.
Public eventEntityDeleting
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.
Public eventEntityInserted
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.
Public eventEntityInserting
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.
Public eventEntityUpdated
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.
Public eventEntityUpdating
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.
Public eventInit
Occurs when the server control is initialized, which is the first step in its lifecycle.
(Inherited from Control.)
Public eventLoad
Occurs when the server control is loaded into the Page object.
(Inherited from Control.)
Public eventPreRender
Occurs after the Control object is loaded but prior to rendering.
(Inherited from Control.)
Public eventUnload
Occurs when the server control is unloaded from memory.
