Do you have form tag in master page or this page?

<%@ Page Title="About" Language="C#" MasterPageFile="~/Site.Master" AutoEventWireup="true" CodeBehind="About.aspx.cs" Inherits="WebApplication2.About" %>

<asp:Content ID="BodyContent" ContentPlaceHolderID="MainContent" runat="server">
    <h2><%: Title %>.</h2>
    <h3>Your application description page.</h3>
    <p>Use this area to provide additional information.</p>
    <input id="Button1" type="button" value="button"  runat="server" onclick="alert('hi'); " onserverclick="Button1_ServerClick"/>
    <asp:Button ID="Button2" runat="server" Text="Button" OnClick="Button2_Click" OnClientClick="alert('hi'); "  />
</asp:Content>

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;

namespace WebApplication2
{
    public partial class About : Page
    {
        protected void Page_Load(object sender, EventArgs e)
        {

        }

        protected void Button1_ServerClick(object sender, EventArgs e)
        {
            Response.Write("hello");
        }

        protected void Button2_Click(object sender, EventArgs e)
        {
            Response.Write("hello");
        }
    }
}

<asp:Button ID="Button1" runat="server" Text="save" 
    OnClientClick="return confirmmation()" onclick="Button1_Click"  />

<script type="text/javascript">
    function confirmmation() {
        return confirm('confirm');
    }
</script>
<asp:Button ID="Button2" runat="server" Text="cancel" CausesValidation="False" 
    onclick="Button2_Click" />

On your refrence i tried the same way and it worked.Both button got postback. May I see your button_save_click event code and your page load code.

Are you sure the markup is correct?

Does it look similar to the following?

<asp:Button ID="ButtonCancel" OnClick="ButtonCancel_Click" />

You need the "OnClick" attribute for it to work.

do you really need to postback just to go to another page? You can just have a javascript call for that:

<input ID="btnCancel" type="button" value="Cancel" onclick="javascript:window.location='/logon.aspx';" />

Make sure you're binding to the event only when IsPostBack is true. Otherwise we won't know without more code.
