A service that allows you to apply row-level filtering to all SELECT queries for the Document Viewer, Report Designer Preview, and Query Builder components.
The Document Viewer, Report Designer’s Preview, and Query Builder call the
ISelectQueryFilterService service before the SqlDataSource executes a SELECT query. Use the CustomizeFilterExpression method to add a conditional clause to each query before it is executed.
