RUNBEAR 2011-11-01 12:06:45



<ext:Store ID="Store1" OnRefreshData="Store1_RefershData"  runat="server" AutoLoad="true">  

     <Proxy>

               <ext:PageProxy/>

         </Proxy>

        <Reader>

            <ext:JsonReader IDProperty="ID">

                <Fields>                    

                <ext:RecordField Name="ID" Mapping="ID" />

                <ext:RecordField Name="Name" Mapping="Name"/>

                <ext:RecordField Name="TypeName" Mapping="TechnologyType.Name"/>

                <ext:RecordField Name="IsSmallUse" Mapping="IsSmallUse" />

                <ext:RecordField Name="IsMediumUse" Mapping="IsMediumUse" />

                <ext:RecordField Name="IsLargeUse" Mapping="IsLargeUse" />

                <ext:RecordField Name="IsHeavyUse" Mapping="IsHeavyUse" />

                <ext:RecordField Name="Remark" Mapping="Remark"/>

                <ext:RecordField Name="CreatedOn" Mapping="CreatedOn" DateFormat="yyyy-MM-dd"/>

                </Fields>

            </ext:JsonReader>

        </Reader>        

    </ext:Store>

提示说这个
<ext:RecordField Name="TypeName" Mapping="TechnologyType.Name"/>
找不到 Name，TechnologyType是引用类型。

第二个问题：



 <ext:TemplateColumn Sortable="false" Header="适用车型">

                                        <Template runat="server">

                                            <Html>

                                                <tpl for=".">

                                                    {IsSmallUse},

                                                    {IsMediumUse},

                                                    {IsLargeUse},

                                                    {IsHeavyUse}

                                                </tpl>

                                            </Html>

                                        </Template>

                                    </ext:TemplateColumn>

{IsSmallUse}这个是int的，我想程序替换成对应的文字信息。怎么替换。js,c#都行。
