i have vb.net form , have added checkbox. using databindings checkbox per below:

txtid.databindings.clear() txtid.databindings.add("text", ds.tables(0), "id")  dim myid new binding("checked", ds.tables(0), "userid") addhandler myid.format, addressof chkformatter addhandler myid.parse, addressof chkparser chkid.databindings.add(myid)

if check box checks fine, once click onto field, checkbox loses check.
