check / uncheck all checkboxes in checkboxgroup

[oliverseitz]

Hi there!

I have a problem... (well, I post here in help... ) :

I have a form with a checkboxgroup (as in checkbox/radiobutton example) but I want an additional checkbox that checks/unchecks all checkboxes of a checkboxgroup.

additional problem: in my checkboxgroup my checkboxes are dynamically loaded from database, this means no fix count of boxes, depending on elements in database.

any idea how to set/unset this dynamic checkboxes?
well, I figured out that I need something like a loop to set checked on true/false, but dont know how to get the count of elements in group to do this...

thanx in advance for help...

bye,
oliver

Each.each seems to return all the checkboxes properly. From there just check to see if data.data[item.name] exists if it does then set the value.

Ext.each(checkgroup.items.items, function(item) {
     console.log(item);
}, this);

any dummy example how this works?

I added a listener to my additional checkboxgroup (with check all checkbox) to check/uncheck all checkboxes in checkboxgroup with fieldname "testgroup".

but how to access this checkboxgroup.

thanx in advance.

bye,
oliver
