When overridden in a derived class, returns the number of rows in the underlying data store that exist within the specified scope.
Assembly: System.Web (in System.Web.dll)
public: virtual int GetCountOfState( PersonalizationScope scope, PersonalizationStateQuery^ query ) abstract
- Type: System.Web.UI.WebControls.WebParts::PersonalizationScope
A PersonalizationScope of the personalization information to be queried. This value cannot be nullptr.
- Type: System.Web.UI.WebControls.WebParts::PersonalizationStateQuery
A PersonalizationStateQuery containing a query. This value can be nullptr.
Return ValueType: System::Int32
The number of rows in the underlying data store that exist for the specified scope parameter.
This method is the abstract definition of an administrative method for retrieving counts of personalization data. Derived implementations should follow the logic described below.
This method passes query wildcard characters to the underlying data store. Support for wildcard characters is currently dependent on how each provider handles characters such as an asterisk (*), a percent symbol (%), or an underscore (_).
Normally, for SQL-compliant data stores, you can perform a wildcard search on a partial path with the wildcard character appearing at the beginning, the end, or the middle of the search string text in the PathToMatch property. For example, to find all paths that start with "~/vdir", the PathToMatch property would be set to "~/vdir%".
Likewise, a wildcard search on a partial user name could have the wildcard character appear at any point in the text string of the UsernameToMatch property. For example, to find all user names that start with "John", the UsernameToMatch parameter would look like "John%".
The following query constraints apply:
If only scope is provided, and query is nullptr or all the properties on query return either nullptr or default values, then all records matching the indicated scope parameter are counted.
If the UserInactiveSinceDate property is not equal to MaxValue, then the counted records are also filtered to return only those records associated with inactive users. The comparison includes records where the LastActivityDate property is less than or equal to the UserInactiveSinceDate property.
Note that this method does not validate combinations of query parameters. For example, code can request a count of personalization state records associated with a specific user name in the shared scope. Because user names are not associated with shared information, the returned count would be zero.
Parameter combinations that have the potential to return a non-zero count include:
Windows 8.1, Windows Server 2012 R2, Windows 8, Windows Server 2012, Windows 7, Windows Vista SP2, Windows Server 2008 (Server Core Role not supported), Windows Server 2008 R2 (Server Core Role supported with SP1 or later; Itanium not supported)
The .NET Framework does not support all versions of every platform. For a list of the supported versions, see .NET Framework System Requirements.
