SqlDataSource - How to use ExpressionEvaluator to programmatically filter report data

This example demonstrates how to use the DevExpress.Data.Filtering.Helpers.ExpressionEvaluator.Fit method to programmatically filter the XtraReport's SqlDataSource query. The Fit operation result is used in the band's BeforePrint event handler to allow or cancel rendering of the band content through the e.Cancel property. Please note that the filter expression should be construct according to the Criteria Language Syntax.
