How can I change input gather from Text to Dropdown
<p>I have a form that gathers data from user inputs from textbox and then inserts it into a database.  One of the fields gathers the company from text, with txtCompanyName being the ID of the textbox.</p>

<pre><code>string CompanyName = txtCompanyName.Text.Trim();
</code></pre>

<p>I want to change this to be a dropdown instead and the form takes that selection and insert into database. I know I need to change txtCompanyName.Text to something else...</p>
