DataList控件使用初步

1、 添加对AspNetPager.dll的引用,配置Web.config文件,以便使用AspNetPager进行分页。
    在Web.config文件的system.web节点下新增配置:
    <pages controlRenderingCompatibilityVersion="3.5" clientIDMode="AutoID">
      <controls>
        <add tagPrefix="webdiyer" namespace="Wuqi.Webdiyer" assembly="AspNetPager" />
      </controls>
    </pages>

2、 前台页面代码
        <asp:DataList ID="DataList1" runat="server" RepeatColumns="3" RepeatDirection="Horizontal"
            Width="220px">
            <ItemTemplate>
                <table style=" 71%; height: 131px;" class="mytable">
                    <tr>
                        <td class="style1">
                            <img alt="" src="<%#Eval("Image") %>" style="height: 28px; 39px" />
                        </td>
                    </tr>
                    <tr>
                        <td>
                            <%#Eval("Name") %>
                        </td>
                    </tr>
                    <tr>
                        <td>
                            <%#Eval("Price","{0:c2}") %>
                        </td>
                    </tr>
                </table>
            </ItemTemplate>
        </asp:DataList>
        <table style=" 100%;" class="mytable">
            <tr>
                <td>
                    <webdiyer:AspNetPager ID="AspNetPager1" runat="server" Width="100%" UrlPaging="true"
                        ShowPageIndexBox="Always" PageIndexBoxType="DropDownList" TextBeforePageIndexBox="Go To Page: "
                        HorizontalAlign=Center PageSize="2" OnPageChanged="AspNetPager1_PageChanged"
                        EnableTheming="true" CssClass="paginator" CurrentPageButtonClass="cpb">
                    </webdiyer:AspNetPager>
                </td>
            </tr>
        </table>

3、 后台代码(结合AspNetPager进行分页)
        protected void Page_Load(object sender, EventArgs e)
        {
            if (!IsPostBack)
            {
                BindData();
            }
        }
        private void BindData()
        {
            string connStr = "server=.\\sqlexpress;database=codematic;integrated security=true";
            using (SqlConnection conn = new SqlConnection(connStr))
            {
                string sql = "select * from P_Product";
                SqlDataAdapter da=new SqlDataAdapter(sql,conn);
                DataTable dt = new DataTable();    
                da.Fill(dt);
                DataView dv = dt.DefaultView;
                AspNetPager1.RecordCount = dv.Count;
                PagedDataSource pds = new PagedDataSource();
                pds.DataSource = dv;
                pds.AllowPaging = true;
                pds.PageSize = AspNetPager1.PageSize;
                pds.CurrentPageIndex = AspNetPager1.CurrentPageIndex-1;
                DataList1.DataSource = pds;
                DataList1.DataBind();
            }
        }
        protected void AspNetPager1_PageChanged(object src, EventArgs e)
        {
            BindData();
        }
如果要提高性能,可以采用数据源分页,请参照AspNetPager使用初步
