How do you draw a vertical line in aspnet?

To draw a vertical line in ASP.NET, you can use CSS to style a <div> element. Set the width to a small value (like 1px) and the height to your desired length. For example:

<code class="language-html"><div style="width: 1px; height: 100px; background-color: black;"></div>
</code>

You can also use an <hr> tag styled with CSS to achieve a similar effect.
