I searched for a while trying to find the answer to this, but to no avail.

I am trying to find the best way (or any way) to dynamically show and hide
groups of TR's. For example, I have a section of about 6 table rows that
all need to be hidden if a certain condition is met. But I don't want to
hide the whole table. And, I don't want to split up the table because the
columns need to remain intact.

I thought about using runat=server on each of the TR's, and just hiding them
each individually, but that just seems really sloppy, and I thought there
had to be a better way to do it. I really need some sort of HTML-less
container that can serve as a wrapper for the TR's without rendering any
additional HTML.

An asplaceHolder would be perfect since it doesn't render any additional
HTML, but it doesn't allow any other nested server controls at design time
(which seems silly). And an aspanel can wrap around any HTML or server
controls, but it renders HTML (div in IE and table in Netscape -- which
really hoses the HTML). And a <span runat=server> doesn't like nested TR's.

I just need some "wrapper" server control that can contain anything (HTML
and Server controls) without rendering ANY HTML on any browser. Seems like
this would be widely used (and needed) feature, but I haven't had much luck
finding such a thing.

Any suggestions would be appreciated.

Thanks in advance for your help!

I use the PlaceHolder around <tr> elements all the time. This might not
work if you are using an asp table object, but if you are, don't....it's
uncessary overhead. Also, maybe it's giving you an error in design view,
but if it is...don't use design view, use HTML view.

Hi,

Why do you think that make the TR runat=server is sloppy ?
runat=server is one of the bases of ASP.NET.

It's not the <tr> elements that the PlaceHolder is having problems with --
it's the server controls that are within my <tr> elements that the
PlaceHolder doesn't support. Like I said, I need something that will allow
both embedded HTML _and_ server controls.

Thanks for your reply, but it doesn't seem like a PlaceHolder is going to
work with this situation.

I don't have a problem with <tr runat=server> at all. In fact, I use that
quite a bit when I'm just wanting to show/hide a certain row. But I just
don't like having to show/hide 6 individual rows when it would be much
cleaner to group them in a container and just show/hide the whole container.

Thanks for your response nonetheless.

Well, the problem is, these TRs are subset of a larger table. So if I split
these TRs into their own table, I'll lose column formatting.

Thanks for the suggestion anyway.

I meant something like heiarchal grid (but without the +). so the
columns formatting is the same.

Hope i was clear

Hmm... not sure if I'm understanding you, but if so, it actually sounds like
this may be more trouble (and less elegant) than just hiding the TRs
individually -- which was Plan B.

I'm surprised that .NET doesn't have some generic container control than can
just wrap around a section of HTML/server controls for easy dynamic
hiding/showing. This is really all I'm looking for.

1) Yes plan B is better.

2) .Net got such controls but you cant use them inside complex HTML tags
(TABLE).

I don't know what you mean...a PlaceHolder can have any type of control
inside of it. Here is a code snippet where I use a place holder and it
works perfectly...in fact....i have place holders embedded inside of
placeholders. I have a repeater and my custom controls in a placeholder. I
have placeholders inside the repeater which is inside another placeholder,
etc, etc. This page builds a grid view of images in 3 columns where the
bottom row may have 1 to 3 cells, so on the OnItemDataBound of the repeater
I Mod the itemindex to decide whether or not I start or end <tr> tags....
