How to hide AspxTextBox?
<p>On a radio button checked event, I hide the div by </p>

<pre><code>document.getElementById("AltYukleniciDiv").style.visibility = 'hidden';
</code></pre>

<p>But, when I use it for an aspxTextBox, it doesn't hide it. Or when I use the ClientInstanceName instead of document.getElementById("  ")</p>

<pre><code>UnvanText.SetVisible(false);    this didn't work either. UnvanText is ClientInsanceName.
</code></pre>

<p>javascript crashes there. I put an allert after that and it never shows it. I have to do it because I hide a div, including everything in it, but it still shows the textboxes that has validation. I don't know how it is possible. Can you tell me a way to hide them all? It used to hide the div with all of its contents before I make some validation settings. </p>
