If it's a bound field, then by default it will be read-only in the regular view and then if you add a edit command link it will be active when you're editing the row. If you want the checkbox to be active in the regular view you'd need to convert it to a template field and then change the checkbox enabled property in the itemtemplate. You then need to have a button to check through all the rows in the gridview to persist the checkbox values that have been changed.

><asp:CheckBoxField DataField="Approved" HeaderText="Approved" SortExpression="Approved" />

which makes it readonly.
