CheckedListBox Select All Items - Windows Forms C#

Question

I have a checkbox that when a checked checks all items in a CheckedListBox. When the checkbox goes unchecked it should uncheck all items in the list.

Code:

 if (checkBoxCheckAllPrivileges.Checked)
   for (int i = 0; i < checkedListBoxUsersWhoSee.Items.Count; i++)
      checkedListBoxUsersWhoSee.SetItemChecked(i, true);
 else
   for (int i = 0; i < listBoxUsers.Items.Count; i++)
    checkedListBoxUsersWhoSee.SetItemChecked(i, false);

Is the problem in this code?
Does the .SetitemChecked work giving it the parameter as false?

Is there any other way to uncheck the items?

Answer 1

You have given wrong item in else part for loop,

if (checkBoxCheckAllPrivileges.Checked)
    for (int i = 0; i < checkedListBoxUsersWhoSee.Items.Count; i++)
        checkedListBoxUsersWhoSee.SetItemChecked(i, true);
else
    for (int i = 0; i < checkedListBoxUsersWhoSee.Items.Count; i++)
        checkedListBoxUsersWhoSee.SetItemChecked(i, false);
