combo
...
box
...
to
...
the
...
Department
...
column
...
in
...
a
...
list
...
of
...
employees.
...
It
...
assumes
...
an
...
employee
...
list
...
called
...
#EMPLIST
...
containing
...
a
...
#DEPTMENT
...
column
...
and
...
a

Info Notice that the value property contains a single period (.). This indicates that the value for the combo box should be the value of the current column of the EMPLIST list.
Notice, also, that the display_mode property is set to $tsml_col_mode.
...
This
...
is
...
a
...
special

the
...
grid
...
to
...
indicate
...
the
...
display

mode
...
defined
...
in
...
the
...
DEF_LIST.
...
Now
...
an
...
on_change
...
action
...
will
...
be
...
added
...
to
...
the
...
combo
...
box
...
to
...
execute
...
a
...
Webroutine
...
when
...
a
...
value
...
is
...
changed.
...
The
...
Webroutine,
...
UpdateDepartment,
...
takes
...
two
...
inputs:
...
EMPNO
...
and
...
DEPTMENT.
...
Set the on_change_wrname
...
property
...
of
...
the
...
combo
...
box
...
to
...
UpdateDepartment.
...
Set the tagfield1 property of the combo box to DEPTMENT.
...
This
...
tells
...
the
...
combo
...
box
...
to
...
submit
...
the
...
selected
...
value
...
of
...
the
...
DEPTMENT
...
column
...
(in
...
the
...
DEPTS
...
list).
...
Set the reentryfield property of the combo box to EMPNO and set the reentryvalue property to ../lxml:column
...
[@name='EMPNO'
...
].
...

...
is
