title: Why is the set variable of a MasterPage empty accessing from Content Page
body: <p>MasterPage:</p>
  
  <pre><code>public string strP;
  
  public void Page_Load()
  {
      strP = @"SELECT * FROM ...";
  }
  </code></pre>
  
  <p>Content Page:</p>
  
  <pre><code>public void Page_Load() {
      if (!Page.IsPostBack) {
          string strO = Master.strP; //strO = null
      }
  }
  </code></pre>
  
  <p>I know I am supposed to use the <code>Page_Init</code> but can someone assist me in ensuring I am able to get the set value of <code>strP</code> from the content page.</p>
