This explanation assumes knowledge of ASP.NET and provides a basic RedBack example.

This page gets passed the Employee Id which it uses to read the First Name. Typically of course we would display many more Employee details, but you get the idea.

    Dim EmpId As String
    Dim FirstName As String

    Private Sub Page_Load(ByVal sender As System.Object, ByVal e As System.EventArgs)
	  Dim obj As New REDPAGESLib.RedObject
	  Dim prop As REDPAGESLib.RedProperty

	  try
	     ' get id passed in query string from link on report
	     EmpId = Request("id")
	     ' open SLRBO
	     obj.Open2("rbexamples", "EXMOD:EmpReader", "", "", "")
	     'now do a read using id passed in from report
	     prop = obj.Property("EmpId")
	     prop.Value = EmpId
	     obj.callMethod("DoRead")
	    ' get data
	     prop = obj.Property("FirstName")
	     FirstName = prop.Value
	  Catch ex As Exception
	     'Set Message label with error message
	     throw ex
	  end try
    end sub
