The EntityDataSourceContextDisposingEventArgs type exposes the following members.
| Name | Description | |
|---|---|---|
![]() | Cancel | Gets or sets a value indicating whether the event should be canceled. (Inherited from CancelEventArgs.) |
![]() | Context | Gets the ObjectContext used by the data source. |
| Name | Description | |
|---|---|---|
![]() | Equals(Object) | Determines whether the specified Object is equal to the current Object. (Inherited from Object.) |
![]() | Finalize | Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.) |
![]() | GetHashCode | Serves as a hash function for a particular type. (Inherited from Object.) |
![]() | GetType | Gets the Type of the current instance. (Inherited from Object.) |
![]() | MemberwiseClone | Creates a shallow copy of the current Object. (Inherited from Object.) |
![]() | ToString | Returns a string that represents the current object. (Inherited from Object.) |
Handle the ContextDisposing event, and set the Cancel() property of the EntityDataSourceContextDisposingEventArgs to true. This prevents the disposal of the ObjectContext. For more information, see Object Context Life-Cycle Management (EntityDataSource).
This example maintains the ObjectContext for future reference by handling the ContextCreated event.
protected void EntityDataSource2_ContextDisposing(object sender,
EntityDataSourceContextDisposingEventArgs e)
{
e.Cancel = true;
}
