the enabled property of checkedlistbox has no impact on check state of items or 2 methods.

msdn links:

• checkedlistbox.setitemchecked()
• checkedlistbox.setitemcheckstate()

update: disabling single item in checkedlistbox instead of disabling whole control not possible out of box.

if want prevent user changing check state of 1 special item, need subscribe itemcheck event of checkedlistbox:

checkedlistbox1.itemcheck += (sender, e) => {     if (e.index == 2)         e.newvalue = checkstate.unchecked; } 

this event fired before check state of item changed. e itemcheckeventargs contains item's index, current check state (currentvalue) , check state shall have afterwards (newvalue).

so setting e.newvalue = checkstate.unchecked prevents item being checked again user.
