所以在我的文档中它说：

public event TreeViewPlusNodeCheckedEventHandler NodeChecked()
  
  You can use this event to run cause a method to run whenever the
  check-box for a node is checked on the tree.

那么，如何在我的文件后面的代码中添加一种方法，该方法将在检查节点时运行？我要运行的方法是：

protected void TOCNodeCheckedServer(object sender, TreeViewPlusNodeEventArgs args)
{

    TreeViewPlusNode aNode = args.Node;
    if (!aNode.Checked)
        return;
    List<string> BaseLayers = new List<string>();
    _arcTOCConfig.BaseDataLayers.CopyTo(BaseLayers);

    List<MapResourceItem> mapResources = new List<MapResourceItem>();

    if (BaseLayers.Contains(aNode.Text))
    {
        foreach (BaseDataLayerElement anEl in _arcTOCConfig.BaseDataLayers)
        {
            if (!aNode.Text.Equals(anEl.Name))
            {
                if (aNode.TreeViewPlus.Nodes.FindByValue(anEl.Name).Checked)
                {
                    aNode.TreeViewPlus.Nodes.FindByValue(anEl.Name).Checked = false;
                    aNode.TreeViewPlus.Nodes.FindByValue(anEl.Name).Refresh();
                    MapResourceItem aMapResource = this.Map1.MapResourceManagerInstance.ResourceItems.Find(anEl.Name);
                    aMapResource.DisplaySettings.Visible = false;
                    this.Map1.RefreshResource(anEl.Name);
                    mapResources.Add(aMapResource);
                    this.Map1.MapResourceManagerInstance.ResourceItems.Remove(aMapResource);
                }
                else
                {
                    MapResourceItem aMapResource = this.Map1.MapResourceManagerInstance.ResourceItems.Find(anEl.Name);
                    mapResources.Add(aMapResource);
                    this.Map1.MapResourceManagerInstance.ResourceItems.Remove(aMapResource);
                }

            }
        }

        foreach (MapResourceItem aMapResource in mapResources)
        {
            int count = this.Map1.MapResourceManagerInstance.ResourceItems.Count - 1;
            this.Map1.MapResourceManagerInstance.ResourceItems.Insert(count, aMapResource);
            this.Map1.MapResourceManagerInstance.CreateResource(aMapResource);
        }
        this.Map1.InitializeFunctionalities();
        this.Map1.Refresh();
    }
}

解决方案

我们需要为事件分配一个委托，并使其运行所需的方法。就像是 ：

TreeViewControl.NodeChecked + =新的TreeViewPlusNodeCheckedEventHandler(TOCNodeCheckedServer)

只需向事件添加处理程序即可。

myTreeView.NodeChecked += new TreeViewPlusNodeCheckedEventHandler(TOCNodeCheckedServer);

或者(因为实际上不需要实例化TreeViewPlusNodeCheckedEventHandler)

myTreeView.NodeChecked += TOCNodeCheckedServer;

这是注册事件处理程序的标准情况

treeView.NodeChecked += TOCNodeCheckedServer;

在表单的初始化方法上，添加

TOCTree.NodeChecked += new TreeViewPlusNodeCheckedEventHandler (TOCNodeCheckedServer);

这将告诉应用在TOCNode触发NodeChecked事件时运行TOCNodeCheckedServer。
