By default, the FilterList property is exAllItems. Use the FilterList property to specify the items being included in the column's drop down filter list. Use the DisplayFilterButton property to display the column's filter bar button. The DisplayFilterDate property specifies whether the drop down filter window displays a date selector to specify the interval dates to filter for. Use the exSortItemsAsc flag to sort ascending the values in the drop down filter list. For instance, the exAllItems OR exSortItemsAsc specifies that the drop down filter window lists all items in ascending order. Add the exIncludeInnerCells flag if you require adding the inner cells value to the drop down filter window.
