Valid and access controls in NestedView

[Alex]

Hello
I have a radgrid, there I have a nestedview with two-TAB controls and within
each tab a repeater control with a checkbox that tells me whether or not
selected an option from my database.
Since the option ItemCommand make it along the repeater and enable or disable the
options with the checkbox, my problem is how do I get each time
checkbox event access Oncheckedchangued return me the id code
grid and the repeater control to scroll it and store control
changes in my database.

I have an option that is to place a button and using the property commandname
ItemCommand capturing the event and do my validations and
routes, not if you have a more direct option to control
checkbox inside the repeater and nestedview.

Thanks

Alex Alfonso
