<p>This is my first time using Crystal reports.I have a store procedure and What i am trying to do is when i highlight a row in <code>datagridview</code> and click report button, that only the highlighted row gets sent to the report viewer page.I have tried some solutions here but no luck.</p>

<pre><code>Imports System.Data.SqlClient
Imports System.IO
Imports CrystalDecisions.CrystalReports.Engine

Public Class frmView
    Dim cn As New SqlConnection("Data Source=.;Initial Catalog=DBSAS;Integrated Security=True")
    Dim cmd As New SqlCommand
    Dim da As New SqlDataAdapter
    Dim dt As New DataTable
    Dim i As Integer
    Dim a As New OpenFileDialog

    Private Sub btnRep_Click(sender As Object, e As EventArgs) Handles btnRep.Click 
            cn.Open()
        Dim report As New ReportDocument
        da.SelectCommand = New SqlCommand("EXEC usplatestDateEnrolled ", cn)
        report.RecordSelectionFormula = "{@studID}" &amp; dgv1.SelectedRows(0).Cells(0).Value
        report.Load("C:\users\agent_edx44\My Documents\Visual studio 2012\projects\SASApp\Rep.rpt")
        frmReport.CrystalReportViewer1.ReportSource = report
        frmReport.CrystalReportViewer1.Refresh()
        frmReport.Show()
            cn.Close()
    End Sub

End Class

<blockquote>
  <p>Invalid report file path in this line</p>
</blockquote>

<pre><code>report.RecordSelectionFormula = "{@studID}" &amp; dgv1.SelectedRows(0).Cells(0).Value
</code></pre>
