Umbraco：列出用戶控制中的子節點

Question

我有一個用戶控件，我需要根據parentID返回子節點。我能夠獲得parentID，但不知道返回子節點的語法。

Answer 1

獲取子節點非常簡單。

不知道你有多遠你的代碼所以這裏的各種選項的完整的例子：

using umbraco.presentation.nodeFactory; 

namespace cogworks.usercontrols 
{ 
    public partial class ExampleUserControl : System.Web.UI.UserControl 
    { 
     protected void Page_Load(object sender, EventArgs e) 
     { 
      //If you just want the children of the current node use the following method 
      var currentNode = Node.GetCurrent(); 

      //If you need a specific node based on ID use this method (where 123 = the desired node id) 
      var specificNode = new Node(123); 

      //To get the children as a Nodes collection use this method 
      var childNodes = specificNode.Children; 

      //Iterating over nodes collection example 
      foreach(var node in childNodes) 
      { 
       Response.Write(string.Format("{0}<br />", node.Name)); 
      } 

      //To get the nodes as a datatable so you can use it for DataBinding use this method 
      var childNodesAsDataTable = node.ChildrenAsTable(); 

      //Databind example 
      GridViewOnPage.DataSource = childNodesAsDataTable; 
      GridViewOnPage.DataBind(); 
     } 
    } 
}
