Hi All,

I am getting this error :
(Additional information: This constraint cannot be enabled as not all values have corresponding parent values.)

And I’m creating this relation
Dim relMemberNat As DataRelation
relMemberNat = New DataRelation("MemNat", myDS.Tables("Nat").Columns("Code"), myDS.Tables("Member").Columns("Nationality"))
myDS.Relations.Add(relMemberNat)

- “Nat” table is the Nationalities list table with “Code” filed as PK
- “Member” table is the Members data table with “Nationality” normal filed stors the "Code" value.

Any idea please.
