FUNCTION SetLBItemUsingColumnDataItem(
dialogID  :LONGINT;
componentID  :LONGINT;
itemIndex  :INTEGER;
subItemIndex  :INTEGER;
columnDataItemIndex  :INTEGER) : BOOLEAN;
def vs.SetLBItemUsingColumnDataItem(dialogID, componentID, itemIndex, subItemIndex, columnDataItemIndex):
    return BOOLEAN

Parameters

dialogID LONGINT id of the dialog that contains the list browser
componentID LONGINT id of the list browser control

Remarks

(Orso, 2015.04.06): this crashes VW 2013 if the cell doesn't have any column data items. Check for the presence of data items in the chosen column using GetNumLBColumnDataItems in order to prevent accidentally using it on cells with no column data items:
IF GetNumLBColumnDataItems(dialogID, listBrowserID, columnIndex) > 0 THEN BEGIN
   IF SetLBItemUsingColumnDataItem(dialogID, listBrowserID, rowIndex, columnIndex, columnDataItemIndex) THEN BEGIN
      { ... }
   END;
END;
