You're very close. Couple of things:

• Your triggers should be AsyncPostBackTriggers as you said you tried.
• Your triggers need an event name.
• Suggestion: This won't prevent your events from firing, but unless you want EVERY postable event to cause a postback, add UpdateMode="Conditional" to your UpdatePanel.

Here is a working example.

Web Form - WebForm1.aspx:

<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="WebForm1.aspx.cs" Inherits="AspDotNetStorefront.WebForm1" %>




    
        
    
    
        

            
            

                
                    
                        

                            
Never clicked
                        
 
                    
                    
                        
                    
                
            
    
        
    

CodeBehind - WebForm1.aspx.cs:

using System;

namespace AspDotNetStorefront
{
    public partial class WebForm1 : System.Web.UI.Page
    {
        private static int _clickedCount = 0;

        protected void lnk1_Click(object sender, EventArgs e)
        {
            ++_clickedCount;
            var suffix = _clickedCount <= 1 ? "time" : "times";
            lnk_1.Text = string.Format("Clicked {0} {1}", _clickedCount, suffix);
        }
    }
}
