Q:
Which delegate of the Custom section should I put the AddObject() method?
A:
There is no delegate involved in creating a custom gadget. Hover the mouse over the gadget header and click the keyboard icon. You will then be in the script editor for that custom gadget. That is where you create your custom gadget UI.

Q:
in a standard section, I've iserted a simple VFP Gadget, with 2 label and 2 textbox.
When I load the page, the gadget is correctly populated.
When I skip records of section, how I can refresh the gadget object?
A:
A custom gadget should have a refresh method which is called when required.
It's a method in the gadget object.
Declare public variables and assign the objects. These public variables should be in a namespace if you edited the custom gadget through the UI.

Q:
I've a Form Section, with a Grid Gadget.
If I try to set:
I get the error:Code:oGridGadget = lianja.get("mypage.section.gridgadget")
oGridGadget.clear()
oGridGadget.setattr("controlSource", "filterricerca")
where filterricerca is a cursor:Quote:
gio ott 6 10:10:16 2016
**** Lianja error ****
USE "filterricerca" IN 0
^
File 'filterricerca.dbf' does not exist
Is possible to use a cursor as a datasource of a Grid Gadget?Code:create cursor filterricerca (&cursorField)
select filterricerca
append blank
A:
No, it expects a table name.
A2:
I believe you can also use temp tables (at least that how I understand them) instead of a cursor.
If you select into a table that has a name that starts with an underscore, it is not part of the database.
select * from a into _temp1.
You can create a temporary table that is not in the database.
I know of two ways.
1. Create table c:\tempfabio free(Firstname Char(10), Id int)
By using the word free, it keeps it standalone.
2. use a table that starts with an underscore.
Select * from masterfabio into table _tempfabio
