Using AJAX CollapsiblePanelExtender

Hello,

I am using a AJAX CollapsiblePanelExtender within a gridView on a webpage.
The page also contains a fieldset with some labels, a dropdown, 2 textboxes and a "submit" button.

Whenever the collapsible panel 'Plus' button (to expand) or the 'Minus' button are pressed - the controls on the page are slightly moving. That doesn't look so good and I would like to prevent that.

how can I do that?

Below is the code in my aspx page.

Thank you

More than likely it has something to do with using the % width in your page instead of fixed width.

Try this instead. You will probably need to tweak the width and the styles a bit, but it may fix the problem.
