[Solved] Child Radgrid is not editable clicking on Edit button

[Fabio Laserra]

Hello
I have a radgrid that, when the row is in Edit Mode, calls a .ascx file that contains some fields and another radgrid. The "child" radgrid is not editable. If I click on Edit link, the EditCommand event is fired but the browser cannot show the inline edit mode. If I move the child radgrid to outside the parent radgrid it works perfectly.

Can anyone give me a suggestion?
Thanks
This is the main radgrid:
