Umbraco: List Child Nodes in User Control
提问by JGrimm
I have a user control in which I need to return child nodes based on parentID. I am able to get the parentID, but don't know the syntax for returning child nodes.

Getting child nodes is pretty straightforward.
获取子节点非常简单。
Not sure how far you are with your code so here's a complete example with the various options:
不确定你的代码有多远，所以这里有一个包含各种选项的完整示例：
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();
}
}
}
