为什么Aspx TreeList中的getallnodes()方法返回0个节点? [英] Why does the method getallnodes() in aspx TreeList return 0 nodes?

问题描述

大家好

这是我的代码:

Hi all

here is my code:

protected void gv_search_SelectedIndexChanged(object sender, EventArgs e)
    {
        IEnumerable<treelistnode> AllNodes = ASPxTreeList1.GetAllNodes();
        
        foreach (TreeListNode node in AllNodes)
        {
            if (node.Key == gv_search.SelectedValue.ToString())
            {
                node.Focus();
                break;
            }
        }
    }</treelistnode>

推荐答案

因为列表中没有任何节点.

我赢了什么?

Because there aren''t any nodes in the list.

What do I win?

您提供的信息太少，无法帮助任何人.
我所建议的最好方法是通过代码(GetAllNodes() 方法)进行调试，并尝试找出为什么没有记录计数返回的原因.

You have provided too little information for anyone to be of assistance to you.
The best I can suggest is debug through the code (the GetAllNodes() method) and try and figure out why no record count is being returned.
