If you use a ListBox, the default behaviour is for only one item to be selected at a time. You can change that behaviour by setting or clearing the .MultiSelect property.

Here is a tutorial you may find helpful.

Using a ListView, you will need to go through every other item and make sure it's unchecked when a new item is checked.

When the first checkbox is clicked, record a reference in a variable somewhere. When any other checkbox is clicked uncheck the old one by reference, and store a reference to the new one. Much more efficient than looping through everything.
