Visibility of servercontrols thrue javascript

[Dahab]

Hi,
Anyone know if it's possible to set the visibilty of a servercontrol thru
javascript.
Think it would go something like this, but its not working:

document.forms[0]['TextBox1'].style.visibility == 'hidden'

Thanks

There is no way to do this.

You can control whether the control is visible in the browser. But this has
nothing to do with the Visible property on the server. In fact, if Visible
is False on the server, the HTML for that control won't even be streamed
down to the client.

Thanks

JavaScript can only control a CSS style attribute if it is set in the
first place. In your case, you must get the server-side control to add a
"style" attribute with the value "visibility: visible;". This is usually
done using the control's Attributes collection.

Note that for this kind of effects, you probably rather want to use
display: "display: block;".

After that, JavaScript can access the element, and modify the style
attribute:

if ( document.getElementById( "TextBox1" )
&& document.getElementById( "TextBox1" ).style
&& document.getElementById( "TextBox1" ).style.display )
{
document.getElementById( "TextBox1" ).style.display = "none";
}
