前台：

代码

每次使用分页的时候只用复制最下面两行即可（可以不用修改控件名）！

后台：

代码

  protected void Page_Load(object sender, EventArgs e)
    {
        if(!IsPostBack)
             bind();
    }

    int pageCount;//总页数
    int currentPage = 1;//第定义当前页
    int count = 10;//每页条数

    private void bind()
    {
        PagedDataSource pds = new PagedDataSource();
        pds.DataSource = GoodsManager.GetAllGoods().DefaultView;

        //允许分页
        pds.AllowPaging = true;
        //设置每页显示记录数
        pds.PageSize = count;
        //获取总页数
        pageCount = pds.PageCount;
        this.Label1.Text = pageCount.ToString();
        pds.CurrentPageIndex = currentPage - 1;
        //当前页
        this.Label2.Text = Convert.ToString(currentPage);

        //数据绑定下拉列表

        this.RepeaterProductList.DataSource = pds;
        this.RepeaterProductList.DataBind();

        DropDownList1.Items.Clear();
        //绑定dropdownlist
        for (int i = 0; i < pageCount; i++)
        {
            DropDownList1.Items.Add((i+1).ToString());
        }
    }

    //截取字符
    public string SubstringStr(string str)
    {
        if (str.Length > 10)
        {
            return str.Substring(0, 10);
        }
        else
        {
            return str;
        }
    }
    protected void RepeaterProductList_ItemCommand(object source, RepeaterCommandEventArgs e)
    {
        //((LinkButton)e.Item.FindControl("LinkBtnDelete")).Attributes.Add("onclick", "javascript:return confirm('你确认要删除吗?')");

        if (e.CommandName == "Delete")
        {
            string idstr = e.CommandArgument.ToString();
            int id = int.Parse(idstr);
            int rs = GoodsManager.DeleteGood(id);
            if (rs > 0)
            {
                this.Page.ClientScript.RegisterStartupScript(this.GetType(), "", "<script>alert('删除成功！')</script>");
                bind();
            }
            else
                this.Page.ClientScript.RegisterStartupScript(this.GetType(), "", "<script>alert('删除失败！')</script>");
        }

    }
    /// <summary>
    /// 第一页
    /// </summary>
    /// <param name="sender"></param>
    /// <param name="e"></param>
    protected void Button1_Click(object sender, EventArgs e)
    {//如果当前不是第一页的时候
        if (this.Label2.Text == "1")
        {

        }
        else
        {
            currentPage = 1;
            bind();
        }
    }
    /// <summary>

    /// </summary>
    /// <param name="sender"></param>

    protected void Button2_Click(object sender, EventArgs e)
    {//如果当前不是最后页的时候
        if (this.Label1.Text == this.Label2.Text)
        {
        }
        else
        {
            currentPage = int.Parse(this.Label2.Text) + 1;
            this.Label2.Text = currentPage.ToString();
            bind();
        }
    }
    /// <summary>

    /// </summary>
    /// <param name="sender"></param>
    /// <param name="e"></param>
    protected void Button3_Click(object sender, EventArgs e)
    {//如果当前不是第一页的时候
        if (this.Label2.Text != "1")
        {
            currentPage = int.Parse(this.Label2.Text) - 1;
            this.Label2.Text = currentPage.ToString();
            bind();
        }
    }
    /// <summary>
    /// 最后一页
    /// </summary>
    /// <param name="sender"></param>
    /// <param name="e"></param>
    protected void Button4_Click(object sender, EventArgs e)
    {//如果当前不是最后一页的时候
        if (this.Label1.Text != this.Label2.Text)
        {
            this.Label2.Text = this.Label1.Text;
            currentPage = int.Parse(this.Label2.Text);
            bind();
        }
    }
    //页面跳转

    protected void DropDownList1_SelectedIndexChanged(object sender, EventArgs e)
    {
        currentPage = int.Parse(DropDownList1.SelectedItem.Text);
        bind();
       // DropDownList1.Items.Clear();
    }

灰色部分是需要更改的，其他部分可以直接拿来复用！
