I rarely use iframes, but I'm using a component that requires one to render
an update panel.

When I run the site, the iframe tag is generated as such:

<iframe id="Upload_ProgressBar1" class="ProgressBar"
src="Progress.aspx?frameborder="0" scrolling="no"
name="Upload_ProgressBar1">
</iframe>

Note that there is no width/height attributes. Also note that there is no
CSS referencing the iFrame.

However, it still seems to render at a default width and height. It appears
roughly 100px tall x 400px wide.

Via javascrpt or CSS, I can make the iframe BIGGER, but I can't seem to make
it smaller than that defined size.

Is there a minimum size that an iframe has to be in browsers?

I'd try to modify the HTML itself, but, alas, the actual iFrame is rendered
from compiled server side code, so I can only access it via javascript or
CSS after the fact.

Hi Darrel,

You should be able to resize the iframe with no problem.
There is something I notice though from the markup you posted:

<iframe id="Upload_ProgressBar1" class="ProgressBar"
src="Progress.aspx?frameborder="0" scrolling="no"
name="Upload_ProgressBar1">
</iframe>

it should be:
<iframe id="Upload_ProgressBar1" class="ProgressBar"
src="Progress.aspx" frameborder="0" scrolling="no"
name="Upload_ProgressBar1">
</iframe>

The quotes in there are wrong. Could that be the problem?

That must have been a cut-and-paste issue.

I'm not sure what the issue was.

I was able to over-ride whatever the issue was by just adding a CSS
declaration on the page:

iFrame {width/height}

The issue appeared to be that the iFrame wasn't getting any inline
width/height attributes so was defaulting to some specific size.

Alas, the code that creates the HTML is a compiled DLL so I couldn't easily
poke around to see what it was doing.

Oh well, the CSS works, and I can subsequently modify that via javascript,
so all's well.
