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.
