Answer 1

Sie müssen sich registrieren zwei Tabellen in cmd.CommandText und in Datagridview zu laden.

cmd.CommandText = "Select si.RegID,si.Name,si.EmailID,si.DOB,si.State,si.Nation,si.Contact1 As Contact, " & _ 
      "si.ParmanentAdd as Address,si.Religion,si.WillNo as si.WillNumber,si.Will," & _ 
      "f.FName as Father, f.MName as Mother, f.MStatus as Marital, f.Degree, f.Childran As Children, f.NOC As NumberOfChild " & _ 
      " FROM SelfInformation si, Family f WHERE si.RegID = f.RegID"
