      Change your script from this:
      Code:
      <script type="text/javascript">
    var change = false; 
    function showmsg(id) {
        var res = confirm("proceed"); 
        if (res)
            change = true; 
    }
</script>
      To simply return the user's response:
      Code:
      <script type="text/javascript">
    function showmsg(id) {
        var res = confirm("proceed"); 
       return res;
    }
</script>
      Then change this:

      Code:
      <asp:Button ID="Button1" runat="server" Text="Button" 
                 OnClientClick = "return change;change=false;" onclick="Button1_Click" />
      To this:

      Code:
       <asp:Button ID="Button1" runat="server" Text="Button" 
                 OnClientClick = "return showmsg(this);" onclick="Button1_Click" />

      When you have a button's OnClientClick set to return False it will prevent the button from posting to the server. The above code calls the JavaScript showmsg() method which was changed to return whether or not the user wants to proceed. If the user selects "no" then it returns false which prevents the button from posting back to the server. Likewise, if the user selects "yes" then the function returns true which will allow it to proceed.

      Please note that you may have to set the button's UseSubmitBehavi or property to False.
