刷新頁面心不是使用樹狀

Question

我試圖用這個命令來更新一個asp.net頁面asp.net工作：

<meta http-equiv="Refresh" content="10"/> 

在該網頁上我有2個樹視圖。刷新工作正常，當我剛剛打開頁面，但是當我點擊一個樹視圖並展開它時，刷新停止工作和頁面不被刷新。

任何想法，爲什麼會發生這種情況？是否有任何連接到樹形視圖被擴大？

這裏是頁的全碼：

public partial class Results : System.Web.UI.Page 
{ 

    protected void Page_Load(object sender, EventArgs e) 
    { 

    } 

    // Function that moves reviewed yellow card to reviewed tree 
    protected void ycActiveTree_SelectedNodeChanged(object sender, EventArgs e) 
    { 
     ycActiveTree.SelectedNode.Text = "Move To Active"; 
     ycReviewedTree.PopulateNodesFromClient = false; 
     ycReviewedTree.Nodes[ycReviewedTree.Nodes.Count - 1].ChildNodes.Add(ycActiveTree.SelectedNode.Parent); 
     Application["reviewedTree"] = new ArrayList(); 
     int count = ((ArrayList)Application["activeTree"]).Count; 
     // Move all the nodes from activeTree application to reviewedTree application 
     for (int i = 0; Application["activeTree"] != null && i < count; i++) 
     { 
      ((ArrayList)Application["reviewedTree"]).Add(((ArrayList)Application["activeTree"])[i]); 
      ((ArrayList)Application["activeTree"]).RemoveAt(0); 
     } 
    } 

    protected void ycActiveTree_TreeNodePopulate(object sender, TreeNodeEventArgs e) 
    { 

     if (Application["idList"] != null && e.Node.Depth == 0) 
     { 

      string[] words = ((String)Application["idList"]).Split(' '); // Yellow Card details 
      TreeNode child = new TreeNode(""); 
      // Go over all the yellow card details and populate the treeview 
      for (int i = 1; i < words.Length; i++) 
      { 
       child.SelectAction = TreeNodeSelectAction.None; 
       // Same yellow card 
       if (words[i] != "*") 
       { 
        // End of details and start of point ip's 
        if (words[i] == "$") 
        { 
         // Add the yellow card node 
         TreeNode yellowCardNode = new TreeNode(child.Text); 
         yellowCardNode.SelectAction = TreeNodeSelectAction.Expand; 

         e.Node.ChildNodes.Add(yellowCardNode); 


         child.Text = ""; 
        } 
        // yellow card details 
        else 
        { 
         child.Text = child.Text + words[i] + " "; 
        } 
       } 
       // End of yellow card 
       else 
       { 
        child.PopulateOnDemand = false; 
        child.SelectAction = TreeNodeSelectAction.None; 

        // Populate the yellow card node 
        e.Node.ChildNodes[e.Node.ChildNodes.Count - 1].ChildNodes.Add(child); 


        TreeNode moveChild = new TreeNode("Move To Reviewed");
