Обновить страницу не работает в asp.net используя treeview

Question

Я пытаюсь обновить страницу asp.net с помощью этой команды:

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

На этой странице у меня есть 2 дерева. Обновление работает нормально, когда я просто открываю страницу, но когда я нажимаю на одно из древовидных представлений и раскрываю его, обновление останавливается, и страница не обновляется.

Есть идеи, почему это может произойти? Есть ли какая-либо связь с расширяемым видом дерева?

Вот полный код страницы:

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

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

Решено, установив для свойства «EnabledClientScript» деревьев значение false.
