I'm utilising the pretty snazzy Gaia ajax toolkit - fairly irrelevant at present to this issue, just thought I'd mention it. Well worth a look!

Anyhow, I have a div on my page which has a panel control in it.  All are set to 100% height/width and it works fine. However, I have an function that needs to know HOW big the 100% is in pixels once rendered and this only seems to be available once the page has completed processing, then my javascript "onload" event fires. Trouble is, this is too late for me to use the values that the javascript function creates by inspecting the height/width of the div that's been drawn.

So... the only way I can think of getting around this is to somehow have javascript call the function that needs the height/width values. This does, of course, mean a postback of some sort and I suppose it has to be ajax (although I'd much rather use the gaia controls, just don't see how to get it working).

How can I get javascript in the "onload" function to call my code-behind function please?
