Question: My calendar extender from the Ajaxtoolkit is sometimes being blocked by nearby dropdownlist controls.

My company uses asp.net 2.0 and IE6 (I know... it sends shivers down my spine too), and at certain scroll positions the problems occurs. 

When it is at correct scroll points the calendar pops up at an acceptable distance away from other controls such as dropdownlists.

I'm not sure if newer versions have this problem but is there a way to avoid it with my current versions? Preferably the popup calendar covers other controls instead of the other way around.

Upgrading is not an option.

Answer: 
[That does not happen for me](http://codepad.org/BHnIMXJa) (and it shouldn't).

It may be a space output somewhere else (use `var_dump()` to view the string).
You might want to look into this thread to see if you want to switch to using DOMDocument. It'll save you a great deal of headaches trying to parse through HTML.
