Name
BindingManagerBase
Synopsis
This class represents a mapping of a property (or column) in a data
source to a property on a Control
. In the case of
simple binding, it uses a bag of Binding
objects
to handle those mappings. For complex data binding, you can derive a
class that handles the data-binding process.
Each binding manager maintains a current Position
in the data source, to allow multiple bound controls to remain in
sync, each control displaying a different column in the same selected
row.
For example, a ListBox
and a
TextBox
can be bound to a data source with same
binding manager (simple binding for the TextBox
providing a Binding
object, complex binding for
the ListBox
without an explicit binding object).
The two will remain synchronized as the ListBox
selection changes. Another ListBox
and
TextBox
bound to the same data source but through
a second binding manager will also remain synchronized with one
another, but will not be synchronized with the first pair. (See
BindingContext
to find out how to create an
independent binding manager for your second pair of controls.)
If the current row in the data source changes, the binding manager
raises PositionChanged
. If the value of the bound
object changes, the CurrentChanged
event is
raised. See CurrencyManager
for information about
how this works in practice, and Binding
for more
information about the data-binding hierarchy.
