Private Sub Save_File()
        Dim fd As OpenFileDialog = New OpenFileDialog()
        fd.Filter = "pdf file|*.pdf"
        If fd.ShowDialog = System.Windows.Forms.DialogResult.OK Then
            Dim filebyte AsByte() = Nothing
            Dim con As SqlConnection = New SqlConnection(ConnStr)
            Dim cmd As SqlCommand = Nothing
            filebyte = File.ReadAllBytes(fd.FileName)
            cmd = New SqlCommand("Insert into tbl_Doc (LYR_Doc) Values(@pdf)", con)
            cmd.Parameters.Add("@pdf", SqlDbType.Binary).Value = filebyte
            con.Open()
            cmd.ExecuteNonQuery()
            con.Close()
            Interaction.MsgBox("File saved into database", MsgBoxStyle.Information)
        EndIf
EndSub

Now I need to read this data and load in the pdfviewer.
I tried as follows. But no result.
 Dim eXactConnection As New SqlClient.SqlConnection(ConnStr)
        Dim eXactCommand As New SqlClient.SqlCommand("SELECT LYR_Doc from tbl_Doc where LYR_Name =  'Arun'", eXactConnection)
        eXactConnection.Open()
        If Not IsDBNull(eXactCommand.ExecuteScalar()) Then
            Dim Docdata As Byte() = DirectCast(eXactCommand.ExecuteScalar(), Byte())
            Using stream As New IO.MemoryStream(Docdata)
                RadPdfViewer1.LoadDocument(stream)
            End Using
        End If
 
Thanks in advance.
