Remarks
Use the FilterCriteria property to create a filter expression that consists of multiple conditions applied to multiple data columns, and apply it to the series data. When you set the FilterCriteria property to a new value, applied filters are reset.
Note that the FilterCriteria and DataSourceAdapterBase.FilterString properties are dependent. If you update one property, the other changes as well.
Use CriteriaOperator descendants to specify the FilterCriteria property. Refer to Criteria Operators for more information.
