repeater控件实现数据绑定并分页

前台：添加一个Repeater 控件 四个LinkButton 控件

        <div class="information">
            <asp:Repeater ID="Repeater1" runat="server">
                <HeaderTemplate>
                    <asp:Label ID="Label1" runat="server" Text="信息与计算科学"></asp:Label></HeaderTemplate>
                <ItemTemplate>
                    <div>
                        <image src=""></image>
                        <asp:Label ID="name" runat="server"><%#DataBinder.Eval(Container.DataItem,"name") %></asp:Label><asp:Label
                            ID="time" runat="server"><%#DataBinder.Eval(Container.DataItem,"name") %></asp:Label>
                    </div>
                </ItemTemplate>
            </asp:Repeater>
            <div>
                当前页码：[<asp:Label ID="labPage" runat="server" Text="1"></asp:Label>] 总页码为：[<asp:Label
                    ID="totalPage" runat="server" Text="totalPage"></asp:Label>]
                <asp:LinkButton ID="lnkbnOne" runat="server" OnClick="lnkbnOne_Click">第一页</asp:LinkButton>
                <asp:LinkButton ID="lnkbnUp" runat="server" OnClick="lnkbnUp_Click">上一页</asp:LinkButton>
                <asp:LinkButton ID="lnkbnNext" runat="server" OnClick="lnkbnNext_Click">下一页</asp:LinkButton>
                <asp:LinkButton ID="lnkbnBack" runat="server" OnClick="lnkbnBack_Click">末  页</asp:LinkButton>
            </div>
        </div>



后台：封装了一个数据绑定的方法，调用执行就能够实现绑定

public void dbBind()
        {
            int curpage = Convert.ToInt32(labPage.Text);
            PagedDataSource ps = new PagedDataSource();
            BLL.tb_teachers tIntroduce = new tb_teachers();//自己写的一个类
            string sql = "proId=1";
            DataSet ds = tIntroduce.GetList(sql);//从数据库查询出数据
            ps.DataSource = ds.Tables[0].DefaultView;
            ps.AllowPaging = true;//允许分页
            ps.PageSize = 2;//每一页显示两条记录
            ps.CurrentPageIndex = curpage - 1;//获取当前页
               lnkbnOne.Enabled = true;
            lnkbnUp.Enabled = true;
            lnkbnNext.Enabled = true;
            lnkbnBack.Enabled = true;

            if (curpage==1)
            {
                lnkbnOne.Enabled = false;//不显示第一页按钮
                lnkbnUp.Enabled = false;//不显示上一页按钮
            }
            if (curpage==ps.PageCount)
            {
                lnkbnNext.Enabled = false;//不显示下一页
                lnkbnBack.Enabled = false;//不显示最后一页
            }

            totalPage.Text = Convert.ToString(ps.PageCount);
            Repeater1.DataSource = ps;
            Repeater1.DataBind();

        }

        //回到首页
        protected void lnkbnOne_Click(object sender, EventArgs e)
        {
            labPage.Text = "1";
            dbBind();
        }
        //上一页
        protected void lnkbnUp_Click(object sender, EventArgs e)
        {
            labPage.Text = Convert.ToString(Convert.ToInt32(labPage.Text)-1);
            dbBind();
        }
        //下一页
        protected void lnkbnNext_Click(object sender, EventArgs e)
        {
            labPage.Text = Convert.ToString(Convert.ToInt32(labPage.Text) + 1);
        }
        //
        protected void lnkbnBack_Click(object sender, EventArgs e)
        {
            labPage.Text =totalPage.Text ;
            dbBind();
        }
