Name
CurrencyManager
Synopsis
This class represents a bag of Binding
objects for
a list-like data source. List-like objects (such as arrays,
collections, and System.Data.DataTable
objects)
implement IList
,
System.ComponentModel.IListSource
, or
System.ComponentModel.IBindingList
. Compare this
with PropertyManager
that deals with simple
properties.
It maintains the concept of the Current
item in
the list. When the current item is changed (by setting the
Position
property, or because the
System.ComponentModel.IBindingList.ListChanged
event was raised), all the objects bound to the data source through
the Binding
objects are updated with the new
value. (See Binding
for details on how this update
can be controlled through the Parse
and
Format
events).
Note that the standard controls such as ListBox
and DataGrid
will update the
Position
automatically as the UI selection
changes.
See Binding
for more information on the
data-binding hierarchy.
