This may seem like an unholy thing to do to a datawindow, but I ran
into a place where it was appropriate. First, I decided that I wanted to
use Don Roof's dropdownfilter service for datawindows, which is
triggered by clicking on a small bitmap icon which is supposed to be
positioned next to the column heading. This is fine for the tabular
style that Don's samples used. However, I wanted to use a grid-style
datawindow to allow my users to resize columns while the application is
running. Unfortunately, the datawindow tries to resize the bitmap when
the column is resized, makin...datawindow expressions using datacolumns from other datawindows

There is no direct way. You could, however, write a couple global
functions... one to set a value, one to get a value (then call these from a
computed field in the DW)... but you're probably better off doing this in a

Difference between Datawindow and datawindowobjects?
- datawindow is a control on a userobject or a window
- datawindowobject (DWObject) is a control within a datawindow, defined in
the dataobject of the datawindow.
You refer to it as <datawindow-instance>.Object.<datawindow object>

When i access/modify object/control from a Datawindow i used

Your description is difficult to understand due to the terminology. First,
a datawindow is assigned to a control - either a datawindow control or a
datastore. Second, the Modify function can only be called within a script.
With that as a basis, can you rephrase the question and describe more
precisely what you want to do? ...datawindow
Add direct setting and getting capability for the datawindow where clause.
This would have to be a string array in case of unions.
Return ONLY the where clause(s) in the main select (in case of sub-selects,
ignore the where clause or somehow list it as a subselect in the where or a
subselect in the select).
It would be great if I could just get and set this as a value and have the
datawindow automatically change (or add) the where clause as specified.
This is for setting the where clause dynamically at run time. Currently

I want to create a datawindow whose only data is three columns that will
themselves be drop-down data windows. These child datawindows will be
populated in PB script with dw_1.GetChild(). When I create that parent
datawindow (New | Datawindow | Freeform), what do I choose in the next
dialog box ("Which datasource would you like to use?") External?
That depends on how you want to populate and use the columns of the main DW.
The DDDW is an edit style that assists the user in selecting a value for the
column in the main DW. If you want to retrieve the values ...modifiyin a datawindow in a datawindow
