Method
PropertyListBox.ValuesForHeader ( HeaderName As String, onlyVisible As Boolean = False ) As Dictionary
You might need to get all values and property names for a given header. Pass the Header name and you will get a dictionary containing all property names with their respective values. Some lines in the header might be hidden. If you do not want to get those values too, set “onlyVisible” to True.
