Can be invoked as on_select-userexit in the widget menu or on_event-userexit in the widget state or in the element selection state of a list widget.
If you invoke the function from the select menu of a list widget, DataView will write the ident number of the selected record into the query buffer of the ident number file of the forms. If at the pre_mask-trigger of the form the userexit dal_wdh_upd_lis or no userexit is installed, DataView will fill the fields of the form with the current data automatically.
