SqlFilter
---------------------------------------------------------
Shows Northwind sales data.

This project uses a SQL query to build a DataTable containing
the NorthWind sales data, then uses this table as a data source
for a C1OlapPage control.

The C1OlapPage allows the user to see different views of the 
data, including an Olap grid and an Olap chart.

The interesting part of this project is that not all data is
loaded into memory at a time. The program updates the SQL 
query with a WHERE clause to include only the customers 
selected by the user in the value filter of the Customer field.
