TcxDataFilterCriteria.OnGetValueList Event

In This Article

Occurs before displaying a dropdown list of values for a filter condition.

#Declaration

Delphi
property OnGetValueList: TcxDataFilterGetValueListEvent read; write;

#Remarks

The dropdown list displays values for a filter condition within which a user can select an element and thus generate a filter condition for a specific item in a container control. You can handle the OnGetValueList event to customize the list before it is displayed on screen. This event fires when a user clicks the filter button displayed in the item’s header.

The Sender parameter provides access to the filter criteria applied to the container control.

The AItemIndex parameter specifies the item’s index. For instance, you can pass a grid column’s Index property as this parameter.

The AValueList parameter specifies the list of values for a filter condition.
