listView.AddToClassList("my-class");
listView.AddToClassList("class-1", "class-2", "class-3");In both examples, the ListView control is specified as "listView". The first example adds a single class "my-class" to the control, while the second example adds multiple classes "class-1", "class-2", and "class-3". This method can be useful when we need to dynamically change the styling of the ListView control based on certain events or conditions. It allows us to add or remove classes on the fly, which can be used to apply CSS rules or other styling properties.
