I have a treeview inside an ajax update panel with ONCollapse & onExpand to trigger the update panel. This is in the masterpage and when clicked i trigger with delegate the inside page, but since i made the update panel, i cant catch the onclick event. I need the treeview on the update panel because i keep its state for retaining the Expanded/Collapsed through the website
public delegate void mstDelegate(object sender, System.EventArgs e);
    public partial class eshop_en : System.Web.UI.MasterPage
    {
        SqlConnection connection10 = new SqlConnection();
        SqlConnection connection100 = new SqlConnection();
        SqlConnection connection200 = new SqlConnection();
        SqlConnection connection300 = new SqlConnection();

        public string[] op = new string[30];

        private string slectedValue;
        public string SlectedValue
        {
            get { return slectedValue; }
            set { slectedValue = value; }
        }
        public event mstDelegate TreeViewEvent;
       
        protected void Page_Load(object sender, EventArgs e)
        {
