What is that, "not in ASP.NET". Please, exact type of "CheckListBox"? Is it WPF, Forms, Silverlight?

You have to iterate through all the items with the index numbers and set the property is enabled to false

Solution 2

To disable any particular item use following
checkedListBox1.SetItemCheckState(0, CheckState.Indeterminate);
SetItemCheckState takes index of item and CheckState Enum
Indeterminate is used to show shaded appearance

thanks Rishikesh_Singh.But i really need disable those items which r checked

Rishikesh_Singh 22-Mar-12 8:01am

yeah sorry about that.. but we really don't have any option in Checkedlistbox to disable. The best option seems to be creating either custom Checkedlistbox control deriving from CheckedListBox
or by using ListBox control and adding Checkbox controls to it like eg given at
