You could think about using Dependent ListBoxes Builder from http://codechargetools.com.
It doesn't require any custom coding.

We've just adapted our Dependent ListBoxes to work inside EditableGrid.

CCT, how your Dependent ListBoxes work? With AJAX or like Nicole's post?

No, no Ajax there, dependent listboxes are filled instantly.

Filled instantly meaning: all listbox variations are build on initialize?
Or is the dependant box rebuild upon changing it's master?
If rebuild with or without submitting the form?

The SIXTO version does build all variations of the dependant listbox in the
HTML's Javascript
which is a NoNo if the tables are very large, but for smaller tables works
ok without form refresh.

Walter,

our dependant ListBoxes completely load all values from datasource at startup. When master selection is changed, values from dependent ListBox are filtered accordingly (master-dependent pairs are kept in rather small JS variable).

This seems to be the best solution without using Ajax. Ajax has advantage of handling really large datasets, but disadvantage of noticeable delay on fetching values.

Thank you for your answer.
Seems both SIXTO and your solution function datawise the same.
I will purchase yours in the days to come to have a go at it.
Sounds good, the AJAX or backchannel load is needed when the dependent table
is large/has many values
it will inflict on the page load size heavily.
So there is your challenge for the next version!
BTW is it two or many dependent LB's ?


Walter

Two or more ListBoxes are supported, demo on the site shows example with 3 ListBoxes.

CCT,

Just bought it.
Buying it, the Shop, works like a charm, fast and easy.
Installation, simple and fast.
The rest, we'll see over the weekend.

Are there any manuals or instructions on how the data should be layed out for use in the Dependent Listbox builder? I keep getting a datatype mismatch error.:-<

There are no special requirements on data, just that dependent ListBox datasource must have field in datasource, that corresponds to bound column in master datasource.

For example you have two tables - countries (country_id, country_name), cities(city_id, city_name, country_id). Here country_id in cities table is the "linking" column.

If you have any questions/problems with our builders, you can always write to support<at>codechargetools<dot>com.
