ektron中的模板化控件

Question

我已经尝试使用分类树检索分类列表，在编辑中我选择分类并获取TaxonomyID，通过使用taxonomyID我想使用模板控件显示使用分类过滤器的数据。我无法检索数据。

    <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>

Answer 1

如果我正确理解了您的问题，那么您有分类法id，并且希望显示该分类法中的所有内容。如果这不是你想要的，那么请澄清你的问题，我将尽我所能提供帮助。

我发现，小部件带来的额外负担有时会使测试正确的API和服务器控件用法变得困难。因此，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的示例显示了用于设置筛选器的声明性语法，您可以将它们直接放入ASPX标记中-就在ContentModelSource控件内。类似于：

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

(更多示例是和。)

但是对于听起来像是你想要完成的事情，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);                
        }
    }
}

需要注意的几件事：

• 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，在这个小部件中，您的属性将使用WidgetDataMember属性进行装饰。
• 代码位于Page_Init事件处理程序中。这一点很重要。在页面的生命周期中，Page_Load为时已晚。我假设这在小部件的上下文中也是正确的。当IsRecursive == true不一定优化时，
• 我的代码。您可以通过turning on caching in the FrameworkAPI获得合理的性能，但是调用api来获取taxonomyData，然后使用它来为内容设置过滤器的想法似乎有点不靠谱。理想情况下，ContentTaxonomyFilter应该有一个“递归”属性。
