Protected Sub FormView1_ItemUpdated(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.FormViewUpdatedEventArgs) Handles FormView1.ItemUpdated
        GridView1.DataBind()
    End Sub

Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
        On Error Resume Next
        Label1.Text = Server.HtmlEncode(Request.Cookies("users")("u_id"))

End Sub

Protected Sub LinkButton1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles LinkButton1.Click

        If FileUpload1.FileName <> "" Then
            FileUpload1.SaveAs(Server.MapPath("video\") & FileUpload1.FileName)
            Label2.Text = FileUpload1.FileName
        End If
        SqlDataSource1.Insert()
        Label1.Text = "lesson added successfuly .. "
