How To Add Textbox With DDL Validation
<p>Straight to the point, I use ASP.NET 3.5 (C#), I have 3 items in my dropdown list.
So, I want to make events within the ddl validation.
For instance,</p>

<pre><code>if (ddl.selectedvalue ==1) { One textbox added to my form }
else if (ddl.selectedvalue==2) { Two textbox added to my form}
</code></pre>

<p>Thank You in advance :)</p>
