Control events

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

• focus grab and lost

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

• enable/disable a control

• before validation – in case of a code selector column, the user can digit a value within the cell editor 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

• value correctly validated – in case of a code selector column, the user can digit a value within the cell editor and when the focus is lost, the validation would start; through this event it is possible to intercept the outcome of the validation task, in case of valid value

• value not correctly validated – in case of a code selector column, the user can digit a value within the cell editor and when the focus is lost, the validation would start; through this event it is possible to intercept the outcome of the validation task, in case of invalid value

• before grid opening – in case of a code selector column, 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

• row selected – in case of a code selector column, the user can select the code from the lookup grid; through this is event it is possible to intercept the grid selection value.

• button click – in case of a button controls, the user can select the action to execute on click.
