I am using the code from the manual to get the primary keys in my table.
They are together in SQL Server:
reqid int 4
itemnum int 4

Public Sub New()
Me.TableName = "pur_item"
Me.PrimaryKeys = New String() {"reqid", "itemnum"}

When I try to get them:
Dim PK As String = grdLineItems.GetCurrentRowPKs.ToString

I get this error:
Attempted to access an element as a type incompatible with the array.

Any ideas on this?

Thanks.
