I have a page with multiple DropDownCheckBoxes controls, one above the other.

On both IE 8 and 9, when I click the Dropdown button, the checkbox list appears behind other DropDownCheckBoxes controls that are below it on the form.
It covers up standard controls such as buttons and text boxes, but also appears beind the Ajax Tool Kit slider control.

Note that this behavior does not happen on Chrome and Firefox. It also does not happen when I am debugging in VS 2010 and the page is hosted by the ASP.NET Development Server.

I confirmed this issue on a “hello world” type page in a site with no CSS files. So I don’t think there is anything else affecting it.
Anybody seen this before and know of a solution?

Your scenario is not that clear, but I think you have custom dropdownlist with checkboxlist as DropDown values and when you open the values area its behind other controls.

Well if it is a custom control, you need to set the the
CSS property of the DropDown values control (either its a div or panel etc.). Set it to a higher value
and test.

Let me know if it helps, or if not please provide me more clear info, may be a little code.

Good luck
