页面代码

后置代码
int index =1;//初始化当前页索引,默认显示第一页 int pageSize = 5;//设置每页显示条数 Common.Page page =null; protected void Page_Load(object sender, EventArgs e) { //前段代码中给当前页标签默认为第一页,用标签保存当前页面索引 index =int.Parse(lblPageIndex.Text); //在页面首次加载的时候,加载总页数,总记录数和信息列表 if (!IsPostBack ) { page = new Common.Page(index, pageSize); this.lblCount.Text = page.Count.ToString(); this.lblPageSum.Text = page.PageSum.ToString(); BookBind(); } } //翻页按钮命令事件 protected void lbtnFirst_Command(object sender, CommandEventArgs e) { page = new Common.Page(index, pageSize); string commandName = e.CommandName; switch (commandName) { case "first": page.PageIndex = 1; break; case "previous": if (index==1) { page.PageIndex = 1; } else { page.PageIndex =index-1; } break; case "next": if (index == page.PageSum) { page.PageIndex = page.PageSum; } else { page.PageIndex=index+1; } break; case "last": page.PageIndex =page.PageSum; break; case "btn": page.PageIndex = int.Parse(txtPageIndex.Text); break; } this.lblPageIndex.Text = page.PageIndex.ToString(); BookBind(); } //给Repeater控件绑定数据 private void BookBind() { this.rpBooks.DataSource = page.CurPager; this.rpBooks.DataBind(); } //获取记录总数的方法 public int GetCount() { return page.Count; } //获取总页数的方法 public int GetPageSum() { return page.PageSum; }
注意事项
本例使用label标签保存当前页面索引,也可以使用视图状态保存。
