    -- Add the parameters for the stored procedure here
@studID INT = NULL

AS
BEGIN

    SET NOCOUNT ON;
SELECT 
            Birthday,getdate() AS [Today],
            Datediff(yy,BirthDay,getdate()) -
            CASE
                WHEN DATEADD(YY, DATEDIFF(YY,BirthDay,getdate()),BirthDay)
                >GETDATE() THEN 1
                ELSE 0

            END AS [age],
        sh.SchoolYear,
        sh.Levels,sh.Section, sh.DateEnrolled ,
        SI.StudentID,SI.Surname,SI.FirstName,SI.MiddleName, SI.StudAddress , 
        SI.BirthDay,SI.Gender, SI.Nationality, SI.BirthPlace,
        SI.TelNum,SI.SchoolWhereGraduated ,

        PI.Father_FirstName,PI.Father_LastName,
        PI.Father_MI,PI.Father_Occupation, 
        PI.Father_TelNUm, PI.Mother_FirstName, PI.Mother_LastName,
        PI.Mother_MI,PI.Mother_Occupation,PI.Mother_TelNum,
        PI.Contact_FirstName,PI.Contact_LastName,PI.Contact_MI,
        PI.Contact_Mobile,PI.Contact_TelNum,PI.Contact_Address  
        FROM StudentInformation SI 
        JOIN StudentHistory SH  
            ON SI.StudentID = SH.StudentID
        JOIN ParentInformation PI
        ON PI.ParentID = SI.ParentID
        WHERE si.StudentID = @studID
        ORDER BY DateEnrolled DESC

            SELECT * FROM StudentHistory WHERE StudentID = @studID
                ORDER BY DateEnrolled DESC
            SELECT TOP 1 SchoolYear,
                Levels,Section, DateEnrolled as LatestDate
                FROM StudentHistory
                WHERE studentID = @studID
                ORDER BY DateEnrolled DESC

vb.net code

Private Sub btnRep_Click(sender As Object, e As EventArgs) Handles btnRep.Click
    FrmExampleReport.Show()
    Dim report As New ReportDocument
    report.Load("C:\users\agent_edx44\Documents\Visual studio 2012\projects\SASApp\SASApp\ExampleReport2.rpt")
    report.SetParameterValue("@studID", dgv1.SelectedRows(0).Cells(0).Value)
    frmReport.CrystalReportViewer1.ReportSource = report
    frmReport.CrystalReportViewer1.Refresh()
End Sub

The Problem is that, it does not load the selected records that i choose in the datagridview, it only loads the record that was selected in the crystal reports. Can anyone help me how to solve the issue.Thanks
