Assembly: System.Windows.Forms (in system.windows.forms.dll)
The value of this property does not necessarily correspond to the current visual position of the column header within the ListView. This can be due to the user reordering the column headers at run time (when the AllowColumnReorder property is set to true). If the ColumnHeader is not contained within a ListView control this property returns a value of -1.
