This example demonstrates how to achieve this task. The CriteriaColumnAffinityResolver.SplitByColumns method is used here to return the dictionary of criteria operators. It is possible to modify them as necessary. Please refer to the ASPxGridView - How to programmatically change the column's filter in the FilterExpression article for more information.
