我尝试使用分类树检索分类列表，在编辑中我正在选择分类并获取分类 ID，通过使用分类 ID 我想使用分类过滤器使用模板化控件显示数据。我无法检索数据。我是附上我所做的HTML和代码，所以请帮助我解决问题。

    <asp:View ID="View" runat="server">          

    <asp:Label ID="lblID" runat="server"></asp:Label>            
    <CMS:Directory CssClass="taxList" ID="TaxonomySummary1" EnableAjax="true" runat="server"
                EnablePaging="false"  />

          <ektron:ContentModelSource ID="cntModelSourcs" runat="server" OrderByField="DateCreated" 
    OrderByDirection="Descending">    


   <TaxonomyFilters>
        <ektron:ContentTaxonomyFilter Operator="Contains"  ID="taxFilter" runat="server" />

    </TaxonomyFilters>

     <ContentFilters>   
       <ektron:ContentFilter Field="Id" Operator="EqualTo" Value=""   />
    </ContentFilters>
</ektron:ContentModelSource>

<ektron:ContentView ID="ContentView1" runat="server"  ModelSourceID="cntModelSourcs"  
    EktronCustomTemplate="Ektron_ContentList_Template" >

</ektron:ContentView>
    </asp:View>

如果我正确理解了您的问题，则您拥有分类 ID 并希望显示该分类中的所有内容。如果这不是你所追求的，那么请澄清你的问题，我会尽我所能提供帮助。

我发现小部件附带的附加包有时会使测试 API 和服务器控制使用的正确性变得困难。出于这个原因，我建议从一个简单的 ASPX 页面开始。

<ektron:ContentModelSource ID="contentModelSource" runat="server">
</ektron:ContentModelSource>

<ektron:ContentView ID="ContentView1" runat="server"  ModelSourceID="contentModelSource" EktronCustomTemplate="Ektron_ContentList_Template">
</ektron:ContentView>

通常，您将找到的模板化服务器控件示例显示了用于设置过滤器的声明性语法，您可以将它们直接放入 ASPX 标记中 - 就在 ContentModelSource 控件中。就像是：

<TaxonomyFilters> 
    <ektron:ContentTaxonomyFilter Field="Id" Operator="EqualTo" Value="208" />
</TaxonomyFilters>

（此处和此处的更多示例。）

但是对于听起来你想要完成的事情，你需要通过代码定义过滤器。这段代码就是这样做的：

protected long TaxonomyId
{
    get
    {
        long id;
        long.TryParse(Request.QueryString["id"], out id);
        return id;
    }
}

protected bool IsRecursive
{
    get
    {
        bool recursive;
        bool.TryParse(Request.QueryString["recursive"], out recursive);
        return recursive;
    }
}

protected void Page_Init(object sender, EventArgs e)
{
    if (TaxonomyId > 0)
    {
        if (IsRecursive)
        {
            var tm = new TaxonomyManager();
            var td = tm.GetItem(TaxonomyId);
            if (td != null)
            {
                var pathFilter = new ContentTaxonomyFilter();
                pathFilter.Field = ContentTaxonomyProperty.Path;
                pathFilter.Operator = CriteriaFilterOperator.StartsWith;
                pathFilter.Value = td.Path;

                contentModelSource.TaxonomyFilters.Add(pathFilter);
            }
        }
        else
        {
            var filter = new ContentTaxonomyFilter();
            filter.Field = ContentTaxonomyProperty.Id;
            filter.Value = TaxonomyId.ToString();
            filter.Operator = CriteriaFilterOperator.EqualTo;

            contentModelSource.TaxonomyFilters.Add(filter);                
        }
    }
}

有几点需要注意：

  • TaxonomyId 是一个属性。我这样做是为了便于在这个简单的 ASPX 页面和自定义小部件之间进行比较，您的属性将使用该WidgetDataMember属性进行装饰。
  • 该代码位于 Page_Init 事件处理程序中。这很重要。Page_Load 在页面的生命周期中为时已晚。我认为这在小部件的上下文中也是如此。
  • 我的何时代码IsRecursive == true不一定是优化的。您可以通过在 FrameworkAPI 中打开缓存来获得合理的性能，但是调用 api 来获取分类数据然后使用它来设置内容过滤器的想法似乎有点不对劲。理想情况下，ContentTaxonomyFilter 将具有“递归”属性。
