I have a table in Sqlserver with Feilds (ID,ParentID,Subject).
Subjects should Fill a Tree in Multiple level.
only Recursive can solve this problem.

And Display Right to Left(RTL) instead of Left to Right(LTR)

please help me with ASP.NET source code (VB).

This question is off topic here. This forum is for the book "ASP.NET Website Programming Prob-Design-Solution".

You should get a book on SQL Server and ADO.NET with VB.NET Syntax.
