Re: [DOTNET] Programmatically accessing Webform HTML
Jim, it IS bad style to mess around with the parent's properties, EXCEPT
with HTML, where you have explicit locations for example to set a JS
include file, or to have something executed at page load. Assume your
server side control wants some javascript executed upon page load....
Messing around with the "parent" properties is pretty often the Body tag
or things in the header - and here the HTML "approach" of never having
been designed for this comes back and hits you full speed.

I see what you mean. Well, this is a shot in the dark, but can you hook
into a Control's child controls at the load or pre-render stage?
Literal
HTML is added to the page as LiteralControls, so maybe you could hunt
for
<body> in the control collection. Doubt it though. Anyway, isn't it
bad
manners to mess around with a parent's properties? If I've set up a
style
for my page control, I don't really want its children screwing with it!

Ok, that's a simple version for the case that the author explicitly
limited it to - but you need to make the body attribute a generic
control. What if a user control wants to add something to the body tag
(which, to my shame, was more what I had in mind - SORRY for the wrong
post here)?

Body.Attributes["bgcolor"] = "green";
...
<body id=Body runat=server>
(It's an HtmlGenericControl)

The next one with this wish :-)
If you find an answer elsewhere, please post it to the list, too -
that's a sometimes necessary thing (especially with the Body tag),
though I think you will find out it is not possible. The HTML does not
exist in a form that is more organized tan a data stream. The stream is
constructed dynamically, and I do not thing you can just add a tag to
the body tag.
BUT - this is only my opinion, I never tried it out severely, so I might
err here.

Subject: [DOTNET] Programmatically accessing Webform HTML
Hello
I would like to programmatically access the elements that exist in the
HTML
view of a Webform from the code behind (aspx.cs) file.
Specifically, I wish to to add an attribute to the BODY element at
runtime.
It's not clear to me how to get at the BODY element from the code behind
page, if it is indeed possible.
thanks, Greg
