You have created two data tables here(table1, table2).

and in both table there is some values, which you are selecting from database..
In your table there is some data which is producing confliction.. Try to remove the conflict between both..

or else just change a line in your code and try

VB

ds.Relations.Add("FK", ds.Tables(0).Columns("ContractorID"), ds.Tables(1).Columns("ContractorID"))

all the best.. :)
