When overridden in a derived class, deletes Web Parts personalization data from the underlying data store based on the specified parameters.
Assembly: System.Web (in System.Web.dll)
- Type: System.String
The path of the personalization data to be deleted. This value can be null but cannot be an empty string ("").
- Type: System.DateTime
The date indicating the last time a Web site user changed personalization data.
Return ValueType: System.Int32
The number of rows deleted from the underlying data store.
This method is the abstract definition of an administrative method for deleting personalization data. Note that this method affects only user personalization data, and not shared data.
Derived implementations should follow the logic described below:
The path parameter cannot contain wildcard characters.
If the provider exposes data from a transaction-aware data store, this method should perform its operations in a single atomic transaction.
If the path parameter is non-null, then only per-user personalization records associated with path will be deleted.
Only per-user personalization records associated with users that are considered inactive since the date indicated in the userInactiveSinceDate parameter will be deleted. Specifically, records where LastActivityDate is less than or equal to UserInactiveSinceDate are deleted.
If both parameters are provided, then records that match both constraints are deleted.
The path parameter can be null.
The path parameter cannot be an empty string. It should be trimmed prior to performing this check.
The UserInactiveSinceDate property cannot be null.
