请教，带翻页页面的全局变量问题

C# code

public partial class queryNoAppCardDept : System.Web.UI.Page{    public string HangSh = "0";//行数    public string YeSh = "0";//页数    public static string s = "";    DataView dv = new DataView();    public Int32 CurrentPageIndex;    protected void Page_Load(object sender, EventArgs e)    {        if (!IsPostBack)        {                   }    }    protected void btnQuery_Click(object sender, EventArgs e)    {            string strSql = "";                    AspNetPager1.CurrentPageIndex = 1;                        if (ddlApartment.SelectedValue.Length == 2)        {            s = "where .................1";        }        else        {            s = "where .................2";        }        int curPage = 0;                if (Request.QueryString["page"] != null)        {            curPage = Convert.ToInt32(Request.QueryString["page"]);        }        else        {            curPage = 1;        }        CurrentPageIndex = curPage;        strSql = "select * from table1 " + s + " order by personno";        dv = dataOperate.getDataView(strSql, curPage, "20", out YeSh, out HangSh);        AspNetPager1.RecordCount = Convert.ToInt32(HangSh);        bindData();    }    void bindData()    {        Repeater1.DataSource = dv;        Repeater1.DataBind();    }    protected void AspNetPager1_PageChanged(object src, EventArgs e)    {            string strSql = "";            int curPage = 0;                    AspNetPager1.CurrentPageIndex = Convert.ToInt32(Request.QueryString["page"]);                if (Request.QueryString["page"] != null)        {            curPage = Convert.ToInt32(Request.QueryString["page"]);        }        else        {            curPage = 1;        }        CurrentPageIndex = curPage;        if (s == "")        {            //xxxxxxxx        }        else        {            strSql = "select from table1 " + s + " order by personno";            dv = dataOperate.getDataView(strSql, curPage, "20", out YeSh, out HangSh);            AspNetPager1.RecordCount = Convert.ToInt32(HangSh);                AspNetPager1.CurrentPageIndex = Convert.ToInt32(Request.QueryString["page"]);                bindData();        }            }}

主要就是这个public static string s = "";
此处用static显然不合适，因为肯定不会只有一个人来访问该页面。

试过session，这个倒是可以，但是短时间内回来在访问这个页面的时候，因为session还有效，这个页面还会用session的条件继续自动查询并显示结果，而我希望离开页面再回来session是空的。

也试过ViewStatus，但是翻页就有问题，不知道怎么解决这个问题？请指教！

这个事情啊，你没看到你代码里面有重复的应用么？

我给你改下！

C# code

public partial class queryNoAppCardDept : System.Web.UI.Page{    public string HangSh = "0";//行数    public string YeSh = "0";//页数    public static string s = "";    DataView dv = new DataView();    public Int32 CurrentPageIndex;    protected void Page_Load(object sender, EventArgs e)    {        if (!IsPostBack)        {                   }    }    protected void btnQuery_Click(object sender, EventArgs e)    {         bindData();    }    void bindData()    {                    string strSql = "";                    AspNetPager1.CurrentPageIndex = 1;                        if (ddlApartment.SelectedValue.Length == 2)        {            s = "where .................1";        }        else        {            s = "where .................2";        }        int curPage = 0;                if (Request.QueryString["page"] != null)        {            curPage = Convert.ToInt32(Request.QueryString["page"]);        }        else        {            curPage = 1;        }        CurrentPageIndex = curPage;        strSql = "select * from table1 " + s + " order by personno";        dv = dataOperate.getDataView(strSql, curPage, "20", out YeSh, out HangSh);        AspNetPager1.RecordCount = Convert.ToInt32(HangSh);        Repeater1.DataSource = dv;        Repeater1.DataBind();    }    protected void AspNetPager1_PageChanged(object src, EventArgs e)    {                bindData();                  }}

可以用一个隐藏控件保存
[解决办法]
viewstate 不好使，估计是在配置文件当中被禁用了
[解决办法]
放url里面吧.
