Question

PagedDataSource objPds = new PagedDataSource();  
            DataSet ds = ucObj.DLPageBind();  
            objPds.DataSource = ds.Tables[0].DefaultView;  
            objPds.AllowPaging = true;  
            objPds.PageSize = 90;  
            int CurPage;              //当前页面从Page查询参数获取   
            if (Request.QueryString["Page"] != null)  
                CurPage = Convert.ToInt32(Request.QueryString["Page"]);  
            else  
                CurPage = 1;              objPds.CurrentPageIndex = CurPage - 1;  
            lblCurrentPage.Text = "Page: " + CurPage.ToString();              if (!objPds.IsFirstPage)  
                lnkPrev.NavigateUrl = Request.CurrentExecutionFilePath + "?Page=" + Convert.ToString(CurPage - 1);              if (!objPds.IsLastPage)  
                lnkNext.NavigateUrl = Request.CurrentExecutionFilePath + "?Page=" + Convert.ToString(CurPage + 1);              ////把PagedDataSource 对象赋给Repeater控件   
            this.DLClass.DataSource = objPds;  
            this.DLClass.DataBind();   这是我从网上找的对datalist的分页，我大体改了改放在用户控件中，但运行之后只有首页没事，在其它页就好像有冲突了  点下一页 页面的其它内容就没了，只有对datalist控件绑定的内容。为什么会这样啊？  这句话啥意思啊：  
Request.CurrentExecutionFilePath + "?Page=" + Convert.ToString(CurPage - 1);  

Answer 1

URL分页,得到currentindexpage值的应该是.

Answer 2

网上有很多datalist分页的例子,曾经找到4,5个方法呢

Answer 3

protected void Page_Load(object sender, EventArgs e)
    {
        if (!IsPostBack)
        {
            ViewState["pageindex"] = "0";
            BindData(); 
        }
    }
    private void BindData()
    {
        DataTable objTable = new DataTable();
        string connectionstring = ConfigurationManager.ConnectionStrings["SQLCONNECTIONSTRING"].ConnectionString;
        using (SqlConnection sc = new SqlConnection(connectionstring))
        {
            using (SqlDataAdapter sda = new SqlDataAdapter("", sc))
            {
                sda.Fill(objTable);
            }
        }
        if (objTable != null && objTable.Rows.Count > 0)
        {
            DataView objView = objTable.DefaultView;
            PagedDataSource objPds = new PagedDataSource();
            objPds.DataSource = objView;            objPds.AllowPaging = true;
            objPds.PageSize = 10;
            objPds.CurrentPageIndex = int.Parse(ViewState["pageindex"].ToString());            if (!objPds.IsFirstPage)
                lkPre.Visible = true;
            else
                lkPre.Visible = false;
            if (!objPds.IsLastPage)
                lkNext.Visible = true;
            else
                lkNext.Visible = false;
            dlData.DataSource = objPds;
            dlData.DataBind();
        }
    }
    protected void IndexChanging(object sender, EventArgs e)
    {
        string strCommand = ((LinkButton)sender).CommandArgument.ToString();
        int pageindex = int.Parse(ViewState["pageindex"].ToString());
        if (strCommand == "pre")
            pageindex = pageindex - 1;
        else
            pageindex = pageindex + 1;
        ViewState["pageindex"] = pageindex;
        BindData();
    }

Answer 4

    private void BindNewsData()
    {
        //datatable实现从数据库获取数据
        DataTable dt = new DataTable();
        string connectionstring = ConfigurationManager.ConnectionStrings["SQLCONNECTIONSTRING"].ConnectionString;
        using (SqlConnection sc = new SqlConnection(connectionstring))
        {
            using (SqlDataAdapter sda = new SqlDataAdapter("", sc))
            {
                sda.Fill(dt);
            }
        }
        ///设定控件的数据源
        //DataList3.DataSource = dt;
        ///绑定控件的数据
        //DataList3.DataBind();
        PagedDataSource objPds = new PagedDataSource();
        objPds.DataSource = dt.DefaultView;
        objPds.AllowPaging = true;
        objPds.PageSize = 10;
        int curPage;
        if(Request.QueryString["Page"]!=null)
            curPage = Convert.ToInt32(Request.QueryString["Page"]);
        else
            curPage = 1;
        objPds.CurrentPageIndex = curPage - 1;
        lblCurrentPage.Text = "Page: " + curPage.ToString();
        if (!objPds.IsFirstPage)
            lnkPrev.NavigateUrl = Request.CurrentExecutionFilePath + "?Page=" + Convert.ToString(curPage - 1);
        if (!objPds.IsLastPage)
            lnkNext.NavigateUrl = Request.CurrentExecutionFilePath + "?Page=" + Convert.ToString(curPage + 1);
        DataList3.DataSource = objPds;
        DataList3.DataBind();
