TcxCustomTreeList.OnFindCriteriaChanged Event

Enables you to identify and track all data search criteria changes applied to the tree list control.

Declaration

property OnFindCriteriaChanged: TcxDataFindCriteriaChangedEvent read; write;

Remarks

This event occurs every time the tree list control updates its content according to the applied data search criteria, after at least one OnFindCriteriaBeforeChange event occurrence. If the tree list control has a large number of nodes, the time interval between the OnFindCriteriaBeforeChange and OnFindCriteriaChanged events can be noticeable. You can handle both events to track the time required to perform a search operation and the changes applied to the active data search criteria.

Refer to the TcxDataFindCriteriaChangedEvent procedural type description for detailed information on parameters accessible within an OnFindCriteriaChanged event handler.

Note

If the tree list control is locked by a BeginUpdate call, all search criteria changes do not take effect until an EndUpdate call that raises the OnFindCriteriaChanged event.
