I am currently using a listbox populated from a masterfile. Im wondering if there is anyway to add a blank line in the listbox? To me it just looks like i should be able to add 

  <OPTION value=nothing selected displaytext=""></OPTION>


but this gets overwritten by the data within the master file and no blank line is added.



 <SELECT id=PERIOD style="Z-INDEX: 2; LEFT: 10px; WIDTH: 100px; POSITION: absolute; TOP: 30px; HEIGHT: 290px" tabIndex=2 size=3 name=PERIOD dfformat="A7" addalloption="0" ibiformat="A7" ibiapp_app="syn_lit_cigar" ibic_server="EDASERVE" datafield="TAX_PERIOD" displayfield="TAX_PERIOD" datasource="DBO_PERIOD.mas" datatype="1" operation numofrecords="-1">
</SELECT>

Can you use the GUI to develop this report?
If so it gives you the ability to add an "ALL" row

What is the purpose of the blank line in the list box? Just a place holder? Can it be selected as a value?

As a general rule, if you can't get what you need using the options provided then you need to manually created the contents of the list box using a procedure and instruct WF to use a procedure instead of a field. If it's inside an HTMLform, you can also execute the procedure and hold, and then manually contruct your list box with something like

<select id=PERIOD name=PERIOD size=3 multiple style="FONT-SIZE: 8pt; FONT-STYLE: normal; FONT-FAMILY: Arial; WIDTH:300px;" >
<OPTION value=" "  selected displaytext=""></OPTION>
!IBI.FIL.HOLDLIST;
</SELECT>

where HOLDLIST is the name of the hold file you created. It will contain the HTML code for the ramainder of your list items.

You would want to make sure that you have some Javascript to make sure that the blank line cannot be selected as a value.

I did use the GUI but the "ALL" is not what im looking for. Basically I wanted to add a blank row so if the row was blank I could pass the blank into the report to do some other tasks.

So is that blank line an acceptable value (comtained in the field values) for that field? Sound like you might just be doing some error checking within your executed fex to see if there is a blank and continue with some other processing. You could do the same with the ALL value. Just add a line like

-SET &NEWVALUE=IF &VALUE EQ 'FOC_NONE' THEN ' ' ELSE &VALUE;

and use &newvalue in your procedure. At least that lets you stay in the GUI for report and launch page development.

Darin

And in stead of using the master file to generate the listbox, you could use a fex to do the same. Difference is that in your fex you can practically do whatever you want/need to do to populate the listbox. It is the way I prefer to do these kind of things.

Perhaps this might also be a solution (http://www.plus2net.com/javascript_tutorial/list-adding.php). It is a pure javascript method.
