Const.PM_DataItemLov
An application or the framework sends the Const.PM_DataItemLov message to a data item in order to invoke the "List-of-Values" dialog.
| Name | Description |
|---|---|
| nWhat = wParam | Standard method parameter. Possible values are Const.METHOD_Inquire, Const.METHOD_Execute, Const.METHOD_GetType |
| lParam | Unused |
When nWhat = Const.METHOD_Inquire, TRUE is returned if the data item has the possibility of using LOV. To have LOV possibility the data item must be enabled and have a reference to an available view.
When nWhat = Const.METHOD_Execute, applications should ignore the return value of this message.
