LinqDataSourceDisposeEventArgs Class


Provides data for the ContextDisposing event.

Namespace:   System.Web.UI.WebControls
Assembly:  System.Web.Extensions (in System.Web.Extensions.dll)


public class LinqDataSourceDisposeEventArgs : CancelEventArgs


Initializes a new instance of the LinqDataSourceDisposeEventArgs class.


Gets or sets a value indicating whether the event should be canceled.(Inherited from CancelEventArgs.)


Gets the data context object to dispose.


Determines whether the specified object is equal to the current object.(Inherited from Object.)


Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection.(Inherited from Object.)


Serves as the default hash function. (Inherited from Object.)


Gets the Type of the current instance.(Inherited from Object.)


Creates a shallow copy of the current Object.(Inherited from Object.)


Returns a string that represents the current object.(Inherited from Object.)

You create a handler for the ContextDisposing event to perform clean-up that is specific to the data context object before the object is destroyed. The LinqDataSourceDisposeEventArgs object contains the data context object that is used when you are selecting, updating, inserting, or deleting data. The ContextDisposing event is raised during the Unload event before the LinqDataSource control disposes the context object.

The data context object is the type specified in the ContextTypeName property or the type set to the ObjectInstance of the LinqDataSourceContextEventArgs class.

When the LinqDataSource control interacts with a database, the ContextTypeName property is set to the DataContext object that represents the database. When the LinqDataSource control interacts with an in-memory data collection, the ContextTypeName property is set to the object that contains the data collection.
