CheckBoxList control provides a method to clear selection from all items: ClearSelection[^]
On the other side there is no such method, but you can create one easily...

C#

for (int i=0; i < Items.Count; i++)
{
  Items[i].Selected = true;
}

(And this is the exact copy of the code from ClearSelection, except the 'true' bit...)
