title: CheckBox control in asp.net (C#)
body: <p>I added a checkbox to my form.</p>
  <p>When the checkbox is checked, some information (TextBox, Label etc.) should appear right under the checkbox.</p>
  <p>How can I do this?</p>

  <pre><code>&lt;asp:CheckBox ID=&quot;CheckBox1&quot; runat=&quot;server&quot; 
          oncheckedchanged=&quot;CheckBox1_CheckedChanged&quot; /&gt;
  </code></pre>

  <pre><code>protected void CheckBox1_CheckedChanged(object sender, EventArgs e)
  {
          
  }
  </code></pre>
