Reloading of Report

I have a problem with loading of report. Everytime i load the form, it reloads the previous data on it. What i want is for the report to load only upon click.

There is no problem on the first click. But when i will preview again a report, the previous is reloaded upon loading. I tried to use dispose, but it still loaded. am i missing something? please help, i am using crystal report on visual studio 2005.

i will appreciate any help, thanks.

This is my code.

Code:

---

    Private Sub btnPreview_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnPreview.Click
        LoadReport()
    End Sub

    Private Sub LoadReport()
        rptsummary.Load(Application.StartupPath & "\Accounting Reports\journal_voucher.rpt")
        Logon(rptsummary, con.Server, con.Database, con.Username, "sa")
        rptsummary.Refresh()
        rptsummary.SetParameterValue("@fxKeyCompany", gCompanyID())
        rptsummary.SetParameterValue("@fiEntryNo", gfiEntryNo)
        rptsummary.SetParameterValue("@preparedby", get_preparedby())
        rptsummary.SetParameterValue("@reviewedby", TextBox1.Text)
        rptsummary.SetParameterValue("@approvedby", TextBox2.Text)
        Me.crvRpt.Visible = True
        Me.crvRpt.ReportSource = rptsummary
    End Sub

    Private Sub frmJournalRpt_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load

    End Sub

    Private Sub frmJournalRpt_FormClosed(ByVal sender As Object, ByVal e As System.Windows.Forms.FormClosedEventArgs) Handles Me.FormClosed
        gfiEntryNo = ""
    End Sub
