Hello,
I have a problem in finding the status of a panel (visible or not). I
have a dropdownlist that associates with a panel in which textbox are
embeded in the panel. A client side VBScript is run when the value of
the dropdown change. And here is the script
if document.all(dr opdown).value ="-1" then
document.all(pa nel).style.disp lay = "block"
else
document.all(pa nel).style.disp lay = "none"
end if
When I do validation at ther server, how do I know if the panel is
visible or not?
Panel.visible is always true, Panel.style("Di splay") is always = ""
I don't want to make the panel visible from the server side, as the
AutoPostBack is really annoying, but I have to do a lot of validation
at the server, is there any suggestion in my approach or how can I get
around that, am I doing something wrong?
Thanks in advance.

Try accessing it's style info via the Style property to see if it was
hidden: http://msdn.microsoft.com/library/de...styletopic.asp
The problem is that on the client-side the viewstate string already says
the panel was visible, and that is a 'static' hidden field. So you have
to know it is 'incorrect'....

On the server, the display style of the div will not be available. Only
posted form data. However, if you can write a JavaScript function that hides
the div, you can certainly write JavaScript that populates a hidden form
field. ;-)

Is there a way I can retrieve the status (visibility) of a server side
panel? If I do it thru' javascript, how can I get the answer from my
aspnet page (server side)
Thanks

Here is what I am working on, I have to check if a textbox is filled or
not. If it is visible, then it must be filled. That's why I need to know
the status (visiblilty) of the panel (in which the textbox embeded in
it). Or is there any workaround?
Thanks
Wanda

Hi,
first, python is one of my fav languages, and i'll definitely keep
developing with it. But, there's 1 one thing what I -really- miss:
data hiding. I know member vars are private when you prefix them with
2 underscores, but I hate prefixing my vars, I'd rather add a keyword
before it.
Python advertises himself as a full OOP language, but why does it miss
one of the basic principles of OOP? Will it ever be added to python?
