    You can call this method based on a user's request or in a report event such as ReportStart to prevent printing a blank report if their data source did not return any records.
    Example
    private void rpt_ReportStart(object sender, System.EventArgs eArgs)
    {
        if (this.DataSource==null)
        {
            this.Cancel();
        }
    }
    Private Sub rpt_ReportStart(ByVal sender As Object, ByVal e As System.EventArgs) Handles MyBase.ReportStart
        If Me.DataSource Is Nothing Then
            Me.Cancel()
        End If
    End Sub
