Hello Jay,

At first you can create relation between datatables which placed in different datasets. This is restriction of ado.net. So you need set special property of StiReport component - CacheAllData to true. You can do this from report designer. After then you can add relation directly in report designer and report engine will create it before report rendering in special cache.

Thank you.

Hai,

I set CacheAllData=True

I have added 2 separate tables like Tabl1, Tabl2 in report designer which has common field as 'RecordNo'.
Then created a relation between them as like:
Parent Datasource as: Tabl1
Child Datasource as: Tabl1
Parent Columns: RecordNo
Child Columns: RecordNo

Give Relation through code as like below:
Dim dataRelation As Dictionary.StiDataRelation
dataRelation = New Dictionary.StiDataRelation("MyRecordNo", report.Dictionary.DataSources("Tabl1"), report.Dictionary.DataSources("Tabl2"), New System.String() {"RecordNo"}, New System.String() {"RecordNo"})
report.Dictionary.RegRelations()
report.Dictionary.Relations.Add(dataRelation)

Add Datasource as like below:
report.RegData("DataSource", ds.Tables("Tabl1"))

But it throws error like:
Tabl2 is not a member of report.Tabl1Datasource: Type 'ParentMyRecordNo' is not defined.

Please guide me how to add relation and multiple datasource through source code.

Thank you
Jay
