Filter events

It is possible to add actions to perform when an event is fired in a filter control. Three events are supported:

• value changed – after losing focus on the filter control, if the value has changed, this event is fired; the user can link an action to execute when the event happened

• before validation – in case of a code selector control, the user can digit a value within the filter control and when the focus is lost, the validation would start; through this event it is possible to intercept the validation task and perform an action just before the validation process: in this way it is possible for instance to apply filtering conditions to the validation request

• before grid opening – in case of a code selector control, the user can select the code from the lookup grid; through this is event it is possible to intercept the grid opening and perform an action just before this event: in this way it is possible for instance to apply filtering conditions to the grid’s data loading request.
