A DevExpress filter control, which is represented by the ASPxFilterControl control, is specifically designed to retrieve data using complex filter conditions. It does not require any SQL syntax and doesn't have any limitations regarding filter condition complexity. With the ASPxFilterControl, you can construct any number of filter conditions, combined by any logical operator, and apply them to controls or to a data source.
Condition Values Hint
To make filtering even easier for end-users, this control can automatically suggest conditions and possible filter values for each individual field.
