IsLoaded Property

RelatedEnd.IsLoaded Property

Gets a value that indicates whether all related objects have been loaded.

Namespace:  System.Data.Objects.DataClasses
Assembly:  System.Data.Entity (in System.Data.Entity.dll)

public bool IsLoaded { get; }

Property Value

Type: System.Boolean
true if the related end contains all the related objects from the database; otherwise, false.



Calling the Load method sets the IsLoaded flag to true.

Calling the Clear method on an EntityCollection<TEntity> sets IsLoaded to false.

An EntityCollection<TEntity> or EntityReference<TEntity> may also be loaded if the related end is included in the query path. For more information about span, see Shaping Query Results (Entity Framework).

The Load method on EntityCollection<TEntity> and EntityReference<TEntity> loads related objects from the data source whether or not IsLoaded is true.

When an object is detached, the IsLoaded flag is changed from false to true.

To guarantee that a related end is fully loaded before doing processing, you should check whether IsLoaded is false. If IsLoaded is false, you should call the Load method.
