These events are triggered on different occasions. The following instructions show the possible event triggers and the exact event sequence. == Event triggers == * Saving records * Discarding changes * Inserting records * Editing records * Deleting records * Row change * Column change * Updating data * Row change in Master == Event examples == * INSERT * UPDATE * DELETE * RESTORE * VALUE CHANGED * ROW SELECTED * COLUMN SELECTED == Saving Records == {{:jvx:client:model:databook:saveselectedrow.png?nolink|}} == Discarding Changes == {{:jvx:client:model:databook:restoreselectedrow.png?nolink|}} == Inserting records == {{:jvx:client:model:databook:insert.png?nolink|}} == Editing records == {{:jvx:client:model:databook:update.png?nolink|}} {{:jvx:client:model:databook:setvalue.png?nolink|}} == Deleting records == {{:jvx:client:model:databook:delete.png?nolink|}} == Row change == {{:jvx:client:model:databook:setselectedrow.png?nolink|}} == Column change == {{:jvx:client:model:databook:setselectedcolumn.png?nolink|}} == Updating data == {{:jvx:client:model:databook:reload.png?nolink|}} == Row change in Master == {{:jvx:client:model:databook:masterchanged.png?nolink|}} === Examples === == Insert == ^Event^Description^ |BEFORE INSERTING|<WRAP> * Change current selection, e.g. to always insert in the first or last row * Throw exception to prevent insertion </WRAP>| |AFTER INSERTING|Set default values| |BEFORE INSERTED|<WRAP> * Input-independent change of values * If writeback is deactivated, a server action can be called to perform the insertion </WRAP>| |AFTER INSERTED|Process server-tier data| == Update == == Delete == == Restore == == Value changed == == Row selected == == Column selected ==
