title: Clear and Reload PDF with axAcroPDF
body: <p>I have a axAcroPDF object with a textbox and two buttons. </p>
  
  <p>Button1 loads Open File Dialog, sends a filename/path to the axAcroPDF object and sends the filename/path to a textbox. </p>
  
  <p>What I want with button3 is to realase the loaded pdf file and clear the filename from the textbox. So that the user can reload another pdf file. </p>
  
  <p>My attempt is below:  </p>
  
  <pre><code>private void button3_Click(object sender, EventArgs e)
          {
              textBox1.Text = String.Empty;
              axAcroPDF1.Dispose();
              axAcroPDF1.setLayoutMode("SinglePage");
              axAcroPDF1.Show();
          }
  </code></pre>
  
  <p>Initially, I've tried with <code>axAcroPDF1.Hide();</code> and <code>axAcroPDF1.Dispose();</code> </p>
  
  <p>This hides the axAcroPDF, but I'm unable to reload a new file. </p>
  
  <p>Any suggestions how I should fix this?</p>
