FlexGrid supports custom filters for specialized filtering requirements.
Implement a custom filter by creating:
A filter class that implements IC1ColumnFilter.
An editor class that implements IC1ColumnFilterEditor.
By default, built-in filters appear together with custom filters. Set ValueFilterEnabled and ConditionFilterEnabled to false to hide the built-in filters.
Export and import filter definitions by using the WriteXml and ReadXml methods.
For more information about implementing custom filters, see Custom Column Filters.
