The current filter expression.
Use the FilterString property to specify a filter expression that consists of multiple conditions applied to multiple data columns, and apply it to the series’ data. Setting the FilterString property to a new value clears any filters that have been previously applied.
Note that the FilterString and Series3DDataSourceAdapter.FilterCriteria properties are dependent. If you update one of them, the other changes as well.
