Get all checked ids when use dynamical xml loading

hi all ,

i have made a simple test by using denamic xml loading . the following is my code :

the example tree looked like this :

item-0 |


| item-1-0 -------

| | item-2-0

| |



| item-1-1

when i checked ‘item-0’ ,i can only get ‘item-0,item-1-0,item-1-1’ but no ‘item-2-0’ .is there anyone could help me to resolve this problem ?

Grid’s methods operate only with loaded items.

So, getAllChecked returns ids of all checked  items (loaded items).
