Panel with vivible=false in source code / large source

[Jens-Oliver Murer]

Hello,

I have a problem with an ASP.Net-application which generates very
large source codes which have to be sent to the clients through 'thin'
lines.
The main problem seems to be a Datagrid which contains several hundred
rows (I'd split them, but our customer wants it this way). I already
disabled the ViewState and cut the source by nearly half.
I use two datagrids on the page, which can be displayed alternately by
setting the visible-parameter of the sourrounding panels of the grids.
I was under the impression that a setting to visible=false would
surpress a rendering of the invisible objects to the source code, as I
had to recognize this isn't the case. Even when the big grid is set to
invisible it is contained in the source-code even though not displayed
to or needed by the user.
Is there a option to surpress the output of invisible objects without
destroying and recreating the objects or re-writing the whole page to
split it up into two pages?

best regards

If you mean server-side, then that is correct. If you are setting visibility
client-side using either the display or visibility style, then this is of
course not the case...

How are you setting the panel's visibility? Could anything in your code be
resetting it?

An easy way to check is to create a Page_PreRender in your page, set a
breakpoint in it, and inspect the value of the Visible property there...

I'm using Panel.visible=f alse
If this internally only triggers a CSS-style I'd understand that the
panel remains in the source, but I thought it would be a server-side
parameter which wouldn't lead to a output in the source.
The visibility of the datagrids are changed on PageLoad when the
decision is made, which of the panels has to be shown.

OK.

The visibility of the datagrids are changed on PageLoad when the
decision is made, which of the panels has to be shown.

And what is the visibility when you break execution in Page_PreRender?
