Answer 1

In the top of he ASPX, just below the @Page tag, add a <%@MasterType… tag.

<%@ Page Language="C#" MasterPageFile="~/masterpage.master" AutoEventWireup="true" CodeFile="page1.aspx.cs" Inherits="page1"%>
<%@ MasterType VirtualPath="~/masterpage.master" %> 

Then, in the code behind:

protected void btnSendMessage_Click(object sender, EventArgs e) 
{  Master.btnAddLink_Click(Nothing,Nothing); }
