MSG-LOAD-ON-DEMAND
This event is fired when the threshold indicated by the
Lod-Threshold property is reached.
The program should load new records in the Grid in response to this event.
The EVENT-DATA-1 data item provides information on the action that triggered the event. Possible values, defined in
isgui.def, are:
Value | Constat in isgui.def | Description |
|---|
1 | grlod-arrow-down-key | The down arrow key was pressed |
2 | grlod-page-down-key | The Pag Down key was pressed |
3 | grlod-ctrl-end-key | The Ctrl-End key combination was pressed |
4 | grlod-scroll-bar-drag | The vertical scroll-bar was dragged to the bottom of the Grid |
5 | grlod-tab-key | The Tab key was pressed and the Grid has the Use-Tab style |
Setting EVENT-ACTION to EVENT-ACTION-COMPLETE prevents the cursor for being moved on the Grid and doesn’t fire a MSG-GOTO-CELL event.
