EntityDataSourceContextDisposingEventArgs Class
Provides data for the ContextDisposing event.
System.EventArgs
System.ComponentModel.CancelEventArgs
System.Web.UI.WebControls.EntityDataSourceContextDisposingEventArgs
Namespace: System.Web.UI.WebControls
Assembly: System.Web.Entity (in System.Web.Entity.dll)
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;
