multiple selection in nested gridview, help please

[sharonrao123]

hello all,

I have a parent gridview company and in this one a nested gridview people, Is it possible to allow the user to select one row or multiple rows from the people gridview using a check box and also get the datakey (in my case personid) of the the rows selected. Please point me in the right direction. This is what i have so far but i have problem accessing the child gridview in the button click event

Cheers, Shilpa.
