c# - Sitecore 使用嵌套转发器正确显示父项和子项

Question

在 sitecore 中我有以下结构:

• Europe
  • Germany
  • France
  • Sweden
• Asia
  • China
  • Thailand
• Middle East
  • U.A.E
  • Iran

我正在使用嵌套转发器在 Asp.net 中显示此结构

<asp:Repeater runat="server" ID="repSubsidiaryList">
<ItemTemplate>
<li>
 <%# Helper.Field(Container.DataItem as Item, "Short Title)%> 
   <asp:Repeater ID="InnerRepeater" runat="server">
     <ItemTemplate>
       <li>
        <%# Helper.Field(Container.DataItem as Item, "Name")%>
       </li>
      </ItemTemplate>
</asp:Repeater>
</li>
</ItemTemplate>
</asp:Repeater>

这是背后的代码:

List<Item> _countryNameItems = new List<Item>(); 
protected void Page_Load(object sender, EventArgs e)
{
    //get the item Subsidaries in sitecore 
    Item mainSubsidiaryFolderItem = Sitecore.Context.Database.GetItem(Settings.GetSetting("SubsidariesFolder"));

    _countryNameItems = mainSubsidiaryFolderItem.Axes.GetDescendants().Where(p => p.TemplateName == "Subsidiary").ToList();

    // binding Subsidiary Folder to a repeater
    repSubsidiaryList.DataSource = mainSubsidiaryFolderItem.GetChildren();
    repSubsidiaryList.DataBind();
}

private void repSubsidiaryList_ItemDataBound(object sender, System.Web.UI.WebControls.RepeaterItemEventArgs e)
{
    RepeaterItem item = e.Item;
    InnerRepeater = (Repeater) item.FindControl("InnerRepeater");
    InnerRepeater.DataSource = _countryNameItems;
    InnerRepeater.DataBind();
}

我得到的结果是这样的:

• Europe
  • Germany
  • France
  • Sweden
  • China
  • Thailand
  • U.A.E
  • Iran
• Asia
  • Germany
  • France
  • Sweden
  • China
  • Thailand
  • U.A.E
  • Iran
• Middle East
  • Germany
  • France
  • Sweden
  • China
  • Thailand
  • U.A.E
  • Iran

我不知道如何获取currentItem然后绑定(bind)数据。

Answer 1

您的内部转发器始终将数据源发送至_countryNameItems。用此替换 ItemDataBound 方法应该会有所帮助:

private void repSubsidiaryList_ItemDataBound(object sender, System.Web.UI.WebControls.RepeaterItemEventArgs e)
{
   // Cast the current dataitem to a Sitecore item
   Item item = (Item)e.Item.DataItem; 
   Repeater innerRpt = (Repeater) e.Item.FindControl("InnerRepeater");      
   // bind the inner repeater to the children of the sitecore item
   innerRpt.DataSource = item.Children; 
   innerRpt.DataBind();
}
