The ASPxFilterControl provides end-users with rich filter criteria construction capabilities:
Add/remove filter expressions
To add and remove filter expressions (conditions), end-users can use the Add and Remove buttons.
Change a field in a filter expression
To change a condition field, end-users can invoke the field dropdown menu and choose the required field.
Change an operator in a filter expression

Edit an expression value

Conditions combined by a logical operator at the same level form a group. End-users can invoke the combining operator dropdown menu to change the current combining operator. Accessible logical operators: And, Or, Not And, Not Or.
