making a table invisible

[Carlos]

Hi all,

I have a table that I would like to make it invsible depending on the
validity of data retrieved. The problem is that within the code behind
the reference to the table is not understood. (i.e. it says that the
html control that I reference with its ID is not declared). How can I
reference it,
and make it invisible ?

Thanks in advance,

Carlos

html code

<table id="myTable" runat="server" cellpadding="0" ... >


vb code:

myTable.visible = False
or
myTable.visible = True

DO NOT set the table's Visible property in code-behind! That will not hide
the table - it will stop it even being rendered to the browser.

Instead, you need to set its visibility style in client-side JavaScript, as
follows:

document.getElementById("<tableID>").style.display="none";

or

document.getElementById("<tableID>").style.display="block";

to make it visible again.

Be aware, though, that some browsers don't understand the display style, so
you may need to use the visibility style instead - there are loads of Google
articles about this...

Well good for you!

It doesn't alter the fact that setting a control's server-side Visible
property to false prevents that control from even being rendered to the
browser.

No doubt to you this looks as if you've hidden the control, but it's not the
same thing at all...

well, my propose is not to render at all, that's the visible = false mean...
if I wnat to colapse I use Atlas for that ;-)

Oh for heaven's sake!

Do all your clients use FireFox too?

What about the poor unfortunates who use Opera...? Or Safari? Or Konqueror
on Linux?

Who gives a damn about them, right...?
