前台直接访问数据库,DataList的数据绑定

前台直接访问数据库.把全部数据取出来就可以.我个人比较喜欢这种方法.很简单.

protected void Page_Load(object sender, EventArgs e)

    {

        if (!IsPostBack)

        {

            listbind();

listbind2();
//listbind3();

        }

    }

    /// <summary>

    /// DataList1的列表

    /// </summary>

    protected void listbind()

    {

        string MenuSQL = "select MenuID,MenuName,MenuUnit,MenuPrice,MenuDesc,OriPrice from wx_bu_Menu";

        //重构之后的代码调用

        PublicDataListBase.ShowDataList(DataList1, MenuSQL);

    }
/// <summary>

    /// DataList2的列表

    /// </summary>

    protected void listbind2()

    {

        string ClassSql = "select ClassName from wx_bu_Class";

        //重构之后的代码调用

        PublicDataListBase.ShowDataList(DataList2, ClassSql);

    }

<asp:DataList ID="DataList2" runat="server" RepeatColumns="1" HorizontalAlign="Justify" RepeatDirection="Horizontal" >

                    <ItemTemplate><a href="index1.html"><li><%# Eval("ClassName")%></li></a></ItemTemplate>

                    </asp:DataList>

                </ul>

                <div class="blank25">

                </div>

            </div>

            <div style="height: 712px; width: 1355px;" id="page_right_contents">

                <div id="products" class="container">

                <asp:DataList ID="DataList1" runat="server" Height="354px" RepeatColumns="1" HorizontalAlign="Justify" RepeatDirection="Horizontal" Width="1355px">

                     <ItemTemplate>

                      <div class="item">

                            <div class="img">

                                <img src="UpLoadCaiPinImages/<%# Eval("MenuID")%>.jpg" onclick="ShowDiv(‘MyDiv‘,‘fade‘)" alt="千岛百叶" />

                            </div>

                            <div class="inkcom">

                                <div class="name" onclick="ShowDiv(‘MyDiv‘,‘fade‘)"><%# Eval("MenuName")%></div>

                                <div class="price">￥<%# Eval("MenuPrice")%>/<%# Eval("MenuUnit")%></div>

                                <s>￥<%# Eval("OriPrice")%></s>

                             </div>

                            <div class="inkcom_bt">

                                  <div class="clearfix goodssbox" id="Div1" style="float: right;">

                                      <span class="lgadd fr" id="Span1">

                                        <input id="btnSub" type="button" value="-" class=‘lgplus‘ />

                                        <input id="txtCount" type="text" value="0" name=‘t1‘ size=‘2‘ class="addtext" maxlength=‘3‘ datatype=‘Number‘ readonly="readonly" msg=‘必须为数字‘ />

                                        <input id="btnAdd" type="button" value="+" class=‘lgminus‘ />

                                        <a id="btnAddstart">点选</a>

                                      </span>

                                  </div>

                            </div>

                            <div class="clear">

                            </div>

                      </div>

                  </ItemTemplate>

                 </asp:DataList>  

这个是公共类库里面的方法.
