panel中名字为依次的顺序（panel1,panel2,panel3,.......），并且所有panel在一个页面里面
priavte void Page_Load(object sender , EventArgs e)
{
     if(!IsPostBack)
       Session["num"]=1;
}
//下一步
private void NextPage()
{
     Panel panel;
     string panelname;
     panelname="Panel"+Session["num"];
     panel=(Panel)FindControl(panelname);
     panel.Visible=false;
     int num=(int)Session["num"];
     num+=1;
     session["num"]=num;
     panelname="Panel"+session["num"];
     panel=(Panel)FindControl(panelname);
     panel.Visible=true;
}
//上一步
private void PrePage()
{
     Panel panel;
     string panelname;
     panelname="Panel"+Session["num"];
     panel=(Panel)FindControl(panelname);
     panel.Visible=false;
     int num=(int)Session["num"];
     num-=1;
     session["num"]=num;
     panelname="Panel"+session["num"];
     panel=(Panel)FindControl(panelname);
