RE: DropLists in ArrayFields - is it possible to have adifferent sele

Question

Richard;
Here you go....
newList : Array of ListElement = new;
{ add elements }
row : Integer = { get your row };
column : Integer = { get by name or just know the number }
// poof! Watch that down cast!
(DropList)(<arrayField>.BodyGrid.GetChildInCell(row,column)).SetElementList(
newList);
You can also change FieldWidget settings....
<arrayField>.BodyGrid.GetChildInCell(row,column).FillColor =
C_BLUE;
My array field doesn't scroll (lucky me!). See if the AfterFieldScrolled
event fires at the right time to recalculate the widget state. I haven't
played with it and I'm far from a Forte GUI guru, but I suspect that you are
altering the column template and the visible widget is separate from the
data. So as you scroll, the data would scroll but the new settings stay
put. That's not what I would want/need. The widget reflects something
about the data. When the data scrolls, so should the presentation
properties!
What may be needed is to somehow derive the presentation state settings
dynamically from the mapped data. So when the data scrolled, the dynamic
settings change on the new presentation row.
Let me know.....

Subject: DropLists in ArrayFields - is it possible to have a
different selection list per row?
I have a DropList in an ArrayField column. Is it possible to have a
different list of selections for each DropList in a different row?
(ex.
DropList #1 in row #1 can choose from a/b/c, whereas a DropList #2
in row
#2 can choose only from d/e/f, etc.) Technote 4996 seems to imply
that it
isn't possible, and everything I've tried so far has failed as well.
Any insight appreciated.

Answer 1

One way to do this is to get at the specific dropList widget in the
arrayField by calling the getChildInCell(Row,Column) method on
<..theArrayField..>.BodyGrid. This widget can then be assigned any
dropList you want. Depending on the uniqueness of the individual
dropLists, each data row specific dropList can be coded as an attribute
(array of ListElement) on the mapped class, which can then be assigned
to the dropList widget.
A code snippet to do this would be -
method refreshArray
begin
for displayRow in 1 to <myArrayField>.VisibleRows do
dataRow : integer = displayRow + <myArrayField>.TopRow - 1;
myDropListWidget : dropList =
dropList(<myArrayField>.BodyGrid.getChildInCell(displayRow,
<..columnNumOfDropList..>));
myDropListWidget.setElementList(myArrayField[dataRow].myElementList);
end for;
end method;
This method has be called only when the user scrolls the arrayField, as
in -
when <myArrayField>.AfterFieldScrolled do
refreshArray();
Hope this helps.
Prashant.
