Drill Detail using VB

[ahhuang]

I m using v8.5 for my crystal report viewer & my code is something like this:

Dim app As New CRAXDDRT.Application
Public Report As CRAXDDRT.Report
Dim db As CRAXDDRT.DatabaseTable
Set Report = app.OpenReport("c:\tmp\jdb\r1.rpt", 1)
For Each db In Report.Database.Tables
db.Location = "c:\tmp\jdb\mydb.mdb"
Next
CRViewer1.ReportSource = Report
CRViewer1.ViewReport

However I wanted to do some action on clicking the detail field in the viewer but it has no response
i used CRViewer1_DrillOnDetail event..

May I noe wat other events or place where i can put some action when clicked on specified field in the detail session?
