TcxVirtualVerticalGrid.OnFindCriteriaBeforeChange Event

Enables you to identify and track any changes made to data search criteria before they take effect on the vertical grid control.

Declaration

property OnFindCriteriaBeforeChange: TcxDataFindCriteriaBeforeChangeEvent read; write;

Remarks

This event occurs every time:

• The DataController.indCriteria.Text, DataController.FindCriteria.UseExtendedSyntax, or DataController.FindCriteria.Behavior property value changes.

• A FindCriteria.AddItem, FindCriteria.RemoveItem, or FindCriteria.ClearItems procedure call changes the list of search sources.

• The vertical grid control changes the list of editor rows available for search operations (for instance, when an editor row’s Options.FilteringWithFindPanel property value changes).
