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="width: 40px; padding: 2px;">
                                    <input type="button" name="btnAddRow" id="btnAddRow" class="btnAddRow" value="增加行"/></td>
                                <td style="width: 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
/*
@名称:新增产品-等级-水平-课题-课题信息
@作者:howie  
@创建时间:2015-3-28
@修改人:
@修改时间:
@修改内容:       
*/




      --定义临时表,用来存放XML转换过来的数据  TrainErp_Product_ProductTopicAfter
      declare @pt_table1 table(FineArtsPoints varchar(50),EncyclopediasPoints varchar(500),CorrespondingA varchar(50),CorrespondingB varchar(50))  
      --对XML数据进行处理,注意下
      DECLARE @pt_idoc1 int --查询下
      exec sp_xml_preparedocument @pt_idoc1 output,@pi_Xml
      insert into @pt_table1  
      select * from openxml(@pt_idoc1,‘/ROOT/TrainErp_Product_ProductTopicAfter‘,1)  
      with(FineArtsPoints varchar(50),EncyclopediasPoints varchar(500),CorrespondingA varchar(50),CorrespondingB varchar(50))  

          
--增加
if @pi_DoCmd=‘add‘
 begin
    begin tran

    insert into TrainErp_Product_ProductTopic
    (
      ProductTopicCode,
      ProductLevelInfoCode,
      TopicName      
    )
  values
    (
      @pi_ProductTopicCode,--生成的编号
      @pi_ProductLevelInfoCode,
      @pi_TopicName
    )
    --从表
    insert into TrainErp_Product_ProductTopicAfter
    select newid(),@pi_ProductTopicCode,FineArtsPoints,EncyclopediasPoints,CorrespondingA,CorrespondingB
    from @pt_table1 where FineArtsPoints !=‘‘
        
    if  @@error<>0
    begin
      rollback tran
      set @po_status = 400
      set @po_RetValue=‘增加失败‘
    end
    else
    begin
      commit tran
      set @po_status = 100
      set @po_RetValue=‘增加成功‘
    end
 end

 --修改
 if @pi_DoCmd=‘modify‘
 begin
                begin tran
                update TrainErp_Product_ProductTopic set
                    ProductLevelInfoCode=@pi_ProductLevelInfoCode,
                    TopicName=@pi_TopicName
                where  ProductTopicCode=@pi_ProductTopicCode
                delete from TrainErp_Product_ProductTopicAfter where ProductTopicCode=@pi_ProductTopicCode
                --从表
                insert into TrainErp_Product_ProductTopicAfter
                select newid(),@pi_ProductTopicCode,FineArtsPoints,EncyclopediasPoints,CorrespondingA,CorrespondingB
                from @pt_table1 where FineArtsPoints !=‘‘
                if  @@error<>0
                begin
                  rollback tran
                  set @po_status = 400
                  set @po_RetValue=‘修改失败‘
                end
                else
                begin
                  commit tran
                  set @po_status = 100
                  set @po_RetValue=‘修改成功‘
                end
        
 end
 --删除
 if @pi_DoCmd=‘delete‘
 begin
        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
        begin
          rollback tran
          set @po_status = 400
          set @po_RetValue=‘删除失败‘
        end
        else
        begin
          commit tran
          set @po_status = 103
          set @po_RetValue=‘删除成功‘
        end
      
end

if @@error <> 0
begin
 set @po_Status = 900
 set @po_RetValue = ‘数据执行失败‘
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
