Getting issue Postedfile is not member of Fileupload.

   Protected Sub GridView1_RowUpdating(sender As Object, e As GridViewUpdateEventArgs)
       Dim file As HttpPostedFile = (CType(GridView1.Rows(e.RowIndex).FindControl("FileUpload1"), fileupload)).PostedFile
       Dim fileName As String = Path.GetFileName(file.FileName)
       Dim oldFileName As String = GridView1.Rows(e.RowIndex).Cells(1).Text
       Dim strConnString As String = System.Configuration.ConfigurationManager.ConnectionStrings("conString").ConnectionString
       Dim con As SqlConnection = New SqlConnection(strConnString)
       Dim strQuery As String = "update tblFiles set FileName=@FileName, FilePath=@FilePath where ID=@ID"
       Dim cmd As SqlCommand = New SqlCommand(strQuery)
       cmd.Parameters.AddWithValue("@ID", GridView1.Rows(e.RowIndex).Cells(0).Text)
       cmd.Parameters.AddWithValue("@FileName", Path.GetFileName(file.FileName))
       cmd.Parameters.AddWithValue("@FilePath", "images/" & fileName)
       cmd.CommandType = CommandType.Text
       cmd.Connection = con
       con.Open()
       cmd.ExecuteNonQuery()
       con.Close()
       file.Delete(Server.MapPath("~/images/") & oldFileName)
       file.SaveAs(Server.MapPath("~/images/") & fileName)
       GridView1.EditIndex = -1
       Response.Redirect(Request.Url.AbsoluteUri)
