Asp.net中使用PageDataSource分页实现代码

复制代码 代码如下:

注:封装数据绑定控件（如 System.Web.UI.WebControls.DataGrid、System.Web.UI.WebControls.GridView、System.Web.UI.WebControls.DetailsView
    //     和 System.Web.UI.WebControls.FormView）的与分页相关的属性，以允许该控件执行分页操作。无法继承此类。
DataList
public DataTable GetDataSet(string sql)
    {
        SqlConnection conn = this.getconn();
        SqlDataAdapter sdr = new SqlDataAdapter(sql, conn);
        DataSet rs = new DataSet();
        sdr.Fill(rs);
        return rs.Tables[0];
    }
    public PagedDataSource PageDataListBind(string sql, int currentPage, int PageSize)
    {
        PagedDataSource pds = new PagedDataSource();
        pds.DataSource = GetDataSet(sql).DefaultView;
        pds.AllowPaging = true;
        pds.PageSize = PageSize;
        pds.CurrentPageIndex = currentPage - 1;
        return pds;
    }

 
DB db = new DB();
    PagedDataSource pds = new PagedDataSource();
    protected void Page_Load(object sender, EventArgs e)
    {
        if (!IsPostBack)
        {

            bind();
        }
    }

    public void bind()
    {
        pds = db.PageDataListBind("select * from tb_word",Convert.ToInt32(lblCurrentPage.Text),2);  
        lnkBtnFirst.Enabled = true;
        lnkBtnLast.Enabled = true;
        lnkBtnPrevious.Enabled = true;
        lnkBtnNext.Enabled = true;
        if (lblCurrentPage.Text == "1")
        {
            lnkBtnFirst.Enabled = false;
            lnkBtnPrevious.Enabled = false;
        }
        if(lblCurrentPage.Text==pds.PageCount.ToString())
        {
            lnkBtnLast.Enabled = false;
            lnkBtnNext.Enabled = false;
        }
        lblSumPage.Text = pds.PageCount.ToString();
        DataList1.DataSource = pds;
        DataList1.DataKeyField = "ID";
        DataList1.DataBind();
    }

    protected void lnkBtnFirst_Click(object sender, EventArgs e)
    {
        lblCurrentPage.Text = "1";
        bind();
    }
    protected void lnkBtnPrevious_Click(object sender, EventArgs e)
    {
        lblCurrentPage.Text = (Convert.ToInt32(lblCurrentPage.Text) - 1).ToString();
        bind();
    }
    protected void lnkBtnNext_Click(object sender, EventArgs e)
    {
        lblCurrentPage.Text = (Convert.ToInt32(lblCurrentPage.Text) + 1).ToString();
        bind();
    }
    protected void lnkBtnLast_Click(object sender, EventArgs e)
    {
        lblCurrentPage.Text = lblSumPage.Text;
        bind();
    }
