title: Change div things in other page
body: <p>I used the code below to make a change in div of the page of this code file:</p>
  
  <pre><code>HtmlGenericControl divTest = Page.FindControl("test") as HtmlGenericControl;   
  divTeste.InnerText = "tested";
  </code></pre>
  
  <p>But now, I want to change another page. Ex.: default.aspx code behind changes a div inner text in the test.aspx ...</p>
  
  <p>The code above isn't appropriated. I want permanent changes. What code should be?</p>
  
  <p>How can I do it?</p>
