框架-主从表

页面直接通过查询语句取值方法
 // DataTable页面查询语句取值方法
 DataTable dtTable = DbService.Instance().QueryDataTable("select * from TrainErp_Product_LevelAfter where ProductCode='" + DbService.DtV(curMainDataTable, "ProductCode") + "' and LevelCode='" + mLevelCode + "'") ?? new DataTable();

主从表
1.列表页保存方法体增加：
$("body").on("click", ".save", function() {
                $.asFormSetHidden(gConfig.gridFormId, "mc", gConfig.mc);
                $.asFormSetHidden(gConfig.gridFormId, "procName", "TrainErp_spProductTopicExecute");
                $.asSetXMLInfo(gConfig.gridFormId,"Xml","TrainErp_Product_ProductTopicAfter");
                var param = {};
                $.asAppSubmitFormProc(
                    gConfig.gridFormId, param, function(retData) {
                        //返回正确的数据
                        if (retData.RetStatus == 100 || retData.RetStatus == 101) {
                            //刷新数据
                            $.asTableReloadData(gConfig.id, queryParams);
                            $("#" + gConfig.gridId).show();
                            $("#" + gConfig.detailId + "").hide();
                        } else {
                            alert(retData.RetValue);
                        }
                    }, function() {
                        //表单提交前进行验证
                        //return true 继续进行
                        //return false 阻止提交
                        //alert("进行验证字段是否合法");
                        if ($.asCheckStringEmpty($("#TopicName").val(), true, "课题名称不能为空！")== false) {
                            $("#TopicName").focus();
                            return false;
                        }

                        return true;
                    }, function() {
                        alert("发生错误,请重新提交");
                    });

                return false;
            });

2.列表页定义从表选择方法
            //增加一行的事件
            $.asButtonEvent("btnAddRow", "click", function() {
                var tplInfo = $("#tplRowInfo").html();
                $("#TrainErp_Product_ProductTopicAfter>tbody").append(tplInfo);

            });
            //删除行事件
            $.asButtonEvent("btnDeleteRow", "click", function() {
                $("input[name='cblProductTopicAfter']").each(function() {
                    if ($(this).prop("checked") == true) {
                        $(this).parent().parent().remove();
                    }
                });
            });

3.列表页编辑从表显示：
<script id="tplRowInfo" type="textml" style="display: none;">
        <tr>
            <td class="w30"><input type="checkbox" name="cblProductTopicAfter" /></td>
            <td class="w100">@Html.Raw(HtmlControlHelper.GetText("FineArtsPoints", "", 40, false, false))</td>
            <td class="w100">@Html.Raw(HtmlControlHelper.GetText("EncyclopediasPoints", "", 40, false, false))</td>
            <td class="w100">@Html.Raw(HtmlControlHelper.GetText("CorrespondingA", "", 40, false, false))</td>
            <td>@Html.Raw(HtmlControlHelper.GetText("CorrespondingB", "", 40, false, false))</td>
        </tr>
    </script>

4.详细页编辑从表赋值取值
String mProductTopicCode = DbService.DtV(curMainDataTable, "ProductTopicCode");
<table class="">
                            <tr>
                                <td style=" 40px; padding: 2px;">
                                    <input type="button" name="btnAddRow" id="btnAddRow" class="btnAddRow" value="增加行"/></td>
                                <td style=" 40px; padding: 2px;">
                                    <input type="button" name="btnDeleteRow" id="btnDeleteRow" class="btnDeleteRow" value="删除行"/></td>
                                <td></td>
                            </tr>
                        </table>
                        <table class="asDataGrid" id="TrainErp_Product_ProductTopicAfter">
                            <tbody>
                            <tr>
                                <th class="w30">选择</th>
                                <th class="w100">美术知识点</th>
                                <th class="w100">百科知识点</th>
                                <th class="w100">对应课程A</th>
                                <th>对应课程B</th>
                            </tr>
                            @{
                                //课题-课题信息管理
                                DataTable curDtProductTopicAfter = AppService.QueryDataTable("ds-ProductTopicAfterEdit", " where ProductTopicCode='" + mProductTopicCode + "'", "FineArtsPoints,EncyclopediasPoints,CorrespondingA,CorrespondingB", "Order by ProductTopicInfoId desc", false) ?? new DataTable();
                                foreach (DataRow dataRow in curDtProductTopicAfter.Rows)
                                {
                                    <tr>
                                        <td class="w30">
                                        <input type="checkbox" name="cblProductTopicAfter"/></td>
                                        <td class="w100">@Html.Raw(HtmlControlHelper.GetText("FineArtsPoints", dataRow["FineArtsPoints"].ToString(), 40, false, false))</td>
                                        <td class="w100">@Html.Raw(HtmlControlHelper.GetText("EncyclopediasPoints", dataRow["EncyclopediasPoints"].ToString(), 40, false, false))</td>
                                        <td class="w100">@Html.Raw(HtmlControlHelper.GetText("CorrespondingA", dataRow["CorrespondingA"].ToString(), 40, false, false))</td>
                                        <td>@Html.Raw(HtmlControlHelper.GetText("CorrespondingB", dataRow["CorrespondingB"].ToString(), 40, false, false))</td>
                                    </tr>
                                }
                            }
                            </tbody>
                        </table>

5.主从表执行存储过程：
set ANSI_NULLS ON
set QUOTED_IDENTIFIER ON
go

ALTER procedure [dbo].[TrainErp_spProductTopicExecute]
(
    --输入参数
     @pi_DoCmd varchar(200),
     @pi_ProductTopicCode varchar(50),
     @pi_ProductLevelInfoCode varchar(50),
     @pi_TopicName varchar(50),     
     @pi_Xml varchar(max),
    --输出参数
     @po_Status int output,
     @po_RetValue varchar(200) output
)
 as

 end
 --删除

        begin tran
        --先删除从表
        delete from TrainErp_Product_ProductTopicAfter where ProductTopicCode=@pi_ProductTopicCode
        --再删除主表
        delete from TrainErp_Product_ProductTopic where ProductTopicCode=@pi_ProductTopicCode
        
        if  @@error<>0

end

6.其他注意点：
a.主从表查询存储过程，注意新建视图，查询视图
b.修改时，详细页需要取附表的值，必须新增一个附表的Edit数据集，用来循环取值
