|FilterTypeEnum||A FilterTypeEnum expression that indicates the filter's type.|
The FilterType property defines the filter's type. By default, the FilterType is exAll. No filter is applied if the FilterType is exAll. The Filter property defines the column's filter. Use the DisplayFilterButton property to display the column's filter button. Use the FilterInclude property to specify whether the child items should be included to the list when the user applies the filter. Use the FilterCriteria property to filter items using the AND, OR and NOT operators.
If the FilterType property is exNumeric, the drop down filter window doesn't display the filter list that includes items "(All)", "(Blanks)", ... and so on.
