This example demonstrates how to apply filtering to a dashboard item's data in OLAP mode.
The OLAP data connection uses the DevExpress demo HTTP data pump available online at demos.devexpress.com/Services/OLAP/msmdpump.dll.
The DashboardOlapDataSource instance is created at runtime.
The filter string uses criteria language syntax specific to Dashboards and includes a dashboard parameter.
OLAP mode supports a limited number of criteria operators.
