Control EventsOfficial Content

Controls present in a form often have associated events, which have to do with the different actions user can perform in runtime on the control. An example might be the Click event in a web environment. 

Depending on the control (and its type and mode: readOnly or not) and on the environment (win, web or smart devices) the events offered.

A subset of these events consists of those who directly have to do with a mouse action (click, double click, right button: in win or web environment) or finger (tap, long tap, double tap, etc.: in smart devices: known as touch events).

Examples of  control events (other than previous) are those that recognize when a non read-only variable or attribute has changed its value (ControlValueChanged event in SD, IsValid event in web), or a page of a paged grid has changed (PageChanged event), etc.
