In all pages, column values
are by default displayed in either multi-record layout or
single-record layout. The default column display arrangement
differs between key column areas and non-key columns areas.

In key column areas, the default column display arrangement is
that only key columns (columns where Key = 1, 2, ...) are
displayed. |
|
·
|
In non-key column areas, the default column display arrangement
is that only non-key columns (columns where Key = No) are
displayed. |
These default rules only apply
to tables where ALL columns have the In Display Selection set to
NULL (the default). In other words, developers can override the
default rules in USoft Definer by setting the "In Display
Selection" (former "In Lookup") column attribute.
The "In Display Selection"
attribute allows developers to influence the default rules
declaratively from USoft Definer.
For each table, the default
arrangement is changed if at least one of the columns within the
table, or within a supertype table of the table, has a (numerical)
value for "In Display Selection" (the default being NULL). In this
case, new default rules apply:
|
·
|
Columns that have a value for "In Display Selection" are shown
by default in all key column areas, in the order indicated by the
(numerical) values of "In Display Selection". |
|
·
|
Columns that do NOT have a value for "In Display Selection" are
shown by default in the non-key column areas, in the order
indicated by their Position attribute. |
Some consequences of the
default rules are:
|
·
|
In result areas, by default, if a column is not displayed in
the multi-record area (on the left-hand side) then it is displayed
in the synchronized single-record area (on the right-hand side);
this is true whether or not developers have set values for In
Display Selection. |
|
·
|
Developers can use In Display Selection to move a column from
one area to the other. |
The default arrangement, and
also the default created by using In Display Selection, can of
course be overridden or further developed by Web Designer
settings.
