Index Property (UltraGridColumn)

The index of this column in the band's column collection
Public ReadOnly Property Index As Integer
public int Index {get;}

The Index property is set by default to the order of the creation of objects in a collection. The index for the first object in a collection will always be zero.

The value of the Index property of an object can change when objects in the collection are reordered, such as when objects are added to or deleted from the collection. Since the Index property may change dynamically, it may be more useful to refer to objects in a collection by using its Key property.

Following code loops throgh all the columns and prints out thier indexes and keys.
