Here is my code which acts wierd and cause memory to increase:

Protected Sub Timer1_Tick(sender As Object, e As EventArgs)

        If panel2.Attributes("class").Contains("hide") Then

            takimadi11.InnerHtml = "Real Madrid" + "<br>" + "5"
            takimadi21.InnerHtml = "Barcelona" + "<br>" + "0"

            Label2.Text = "555"

            panel2.Attributes("class") = "display"
            panel1.Attributes("class") = "hide"
        Else
            takimadi1.InnerHtml = "Fenerbahçe" + "<br>" + "2"
            takimadi2.InnerHtml = "Galatasaray" + "<br>" + "0"



            panel1.Attributes("class") = "display"
            panel2.Attributes("class") = "hide"
        End If


        BindGrid()
    End Sub
