Are you calling it before the initialize method which creates the controls and also enables them ? It should work, it will disable all buttons, you need to reenable the ones you don't want to disable.

this might have the problem that buttons inside panels or frames are not disabled (just use a recursive walker). Concerning your question: as was said before: disable all and then enable the ones you like or give every button a describing Tag (for example a groupname or whatever) and check for this Tag in you foreach-loop to only disable the ones in the given group.

if you replace
if (ctrl.GetType() == typeof(Button))byif (ctrl is Button)you get simpler code, that recognizes Buttons as well as controls that inherit from Button. :)Luc Pattyn [Forum Guidelines] [My Articles]
