TdxCustomListView.OnDataHint Event

In This Article

Allows you to update information about a range of items when they change in virtual mode.

#Declaration

Delphi
property OnDataHint: TdxListViewOwnerDataHintEvent read; write;

#Remarks

This event occurs when the List View content changes in virtual mode (when the control’s OwnerData property is set to True). For example, the List View control in virtual mode raises this event when a user scrolls the control’s client area. The OnDataHint event allows you to prepare information about list items for later use.

Note

The range of items specified in the OnDataHint event does not always match the range of items for which the OnData event occurs. You should update individual items outside the range in the OnData event handler.

Refer to the TdxListViewOwnerDataHintEvent type description for information on available options.
