how to access the checkbox control in nested gridview

[SharonRao]

hello all, I have master detail gridview master gridview company and detail gridview is peoplelist, i wanted to implement multiple selection in detail gridview using checkboxes. But i am not sure how to get the datakey (in mycase personid) of all the rows in which the checkbox is selected. I need to do insert operation using these personid's can anyone point me in the right direction. Cheers, Shilpa. I am trying to access the child gridview in this method but not able to do so GridView People = grdCompanyPeople.FindControl("grdPersons")as GridView for (int i = 0; i < People.Rows.Count; i++) { GridViewRow Singlerow = People.Rows[i]; bool isChecked = ((CheckBox)Singlerow.FindControl("chkSelect")).Checked; if (isChecked == true) { str.Append(People.DataKeys[Singlerow.RowIndex]["PersonID"].ToString() + ","); } } // prints out the result Response.Write(str.ToString());

Thanks in Advance for your help. Best Regards
