                        </ListView.View>
                    </ListView>

cs code

 lstvPermissions.ItemsSource = AS.Tbl_PersonRolesDetail.ToList();

my above code working fine and look like this:

selected permissions insert database and show these roles in datagrid, now when I click datagrid edit button title field and description field filled but I don't no how I load checked checkboxes to see previously I assigned permissions. Thanx in advance for any help.
