Chip:
Here’s some ALP code that uses that command - it might give you some ideas…
*Case of*
*:* ($formEvent_L=On Drop)
*Case of*
*:* ($currentObjectName_T="Lock_CustomerName”)
*C_BLOB*($blob_X)
*GET PASTEBOARD DATA*("net.e-node.alp.object";$blob_X)
*If* (OK=1)
*C_LONGINT*($eList)
$eList:=*BLOB to longint*($blob_X;Native byte ordering)
*C_LONGINT*($row_L)
$row_L:=*AL_GetAreaLongProperty* ($eList;ALP_Area_DragSrcRow)
$text_T:=*AL_GetAreaTextProperty* ($eList;ALP_Area_Name)
*Case of*
*:* ($eList=eLineItem)
*GOTO SELECTED RECORD*([Line Items];$row_L)
*OBJ_GPBN* ($currentObjectName_T)->:=[Line Items]Product Name
*UNLOAD RECORD*([Line Items])
*:* ($text_T="theOne_List_eList_01")
*C_TEXT*($id_T)
$id_T:=*AL_GetCellTextProperty* ($eList;$row_L;1;ALP_Cell_Value)
*OBJ_GPBN* ($currentObjectName_T)->:=*AL_GetCellTextProperty*
($eList;$row_L;2;ALP_Cell_Value)
*PROC_FormEvent_Set* ($h_;On Data Change)
*PROPOSALS_FC* ($h_)
*End case*
*End if*
*End case*
*End case*
