asp.net分頁代碼2 調(diào)用部分：

在aspx中增加label等元素。

< asp:label id="currentpage" runat="server" CssClass="gray">當(dāng)前頁< /asp:label>                                           < asp:label id="totalpage" runat="server" CssClass="gray">Label< /asp:label>                < asp:hyperlink id="lnkfist" runat="server" CssClass="gray">首頁< /asp:hyperlink>|              < asp:hyperlink id="lnkprev" runat="server" CssClass="gray">前頁< /asp:hyperlink>|              < asp:hyperlink id="lnknext" runat="server" CssClass="gray">下頁< /asp:hyperlink>|              < asp:hyperlink id="lnklast" runat="server" CssClass="gray">尾頁< /asp:hyperlink>

在aspx.cs中增加調(diào)用代碼。

private ContentPager pager;    protected void Page_Load(object sender, EventArgs e)      {          int id = Convert.ToInt32(Request.QueryString["id"]);//接收參數(shù)，例如訪問這個頁是xxx.aspx?id=1          DataSet ds = new DataSet();           //從數(shù)據(jù)庫讀內(nèi)容部分就略掉了           DataRow drow;          drow = ds.Tables[0].Rows[0];          string cont = drow["content"].ToString();//此部分可以把內(nèi)容中的HTML代碼轉(zhuǎn)換一下，我也省略了                 //文章分頁,關(guān)鍵部分           pager = new ContentPager();           pager.Lnknext = this.lnknext;          pager.Lnkprev = this.lnkprev;          pager.Lnklast = this.lnklast;          pager.Lnkfist = this.lnkfist;          pager.Pagenum = this.currentpage;          pager.Pagecount = this.totalpage;          pager.DisplayContent = this.content;           string query = "&id=" + Request.QueryString["id"].ToString();          pager.datapager(cont, query);  }
