Overview The Windows Form Object Model provides a reliable data binding architecture that you can use the schema to write data providers and data users. The Windows Form Object Model supports the data provider based data binding and interface-based data binding. In addition, the Windows Form Object Model also supports multiple interfaces to extend existing control behavior and add a variety of binding behaviors to custom classes.
Windows forms can be bound to a class of public properties, or bind to support
Any class of the IList interface, for example
DataView class,
ARRAY class,
ArrayList class and
Collection class. Unlike the ASP.NET web form, the Windows Form Object Model does not support binding to
DataReader object or
The IEnumerable interface, because it needs to be backwarded backwards when binding any other objects of the non-simple object.

Architecture Windows Form Object Model Supports two different binders:
PropertyManager CurrencyManager you can use
The PropertyManager class binds the simple control into a class of public properties. But can't use
PropertyManager Binds complex controls, for example
Listbox control,
ComboBOX control or
DataGrid control.
can use
CurrencyManager class binds simple controls or complex controls to support
Objects of the IList interface, for example
DataView object,
ARRAY object,
ArrayList object and
Collection object.
Use support
A custom class for the IBIndingList interface, you can sort the list, or add and delete items in the list. These controls are bound to the public properties of the object returned by the list. This object can support
The ICUSTOMTYPEDEScriptor interface is bound to an attribute of an index, not a public property. In addition, this object also supports
IepITableObject interface to provide you can pass
Beginedit method,
EndEdit method and
Canceledit method Access changes.
With bind to ADO
The Recordset object is different,
The ILIST interface does not track the "current" record. therefore,
ILIST interface does not include
MoveFirst method,
MoveNext method,
MovePRevious method and
MoveLast method.
CurrencyManager is through
Position attributes maintaining currency and you can increment and deliver this property to traverse records.
If you want to inform you when you navigate, make sure your application hook (HOOK)
Currencymanager
PositionChanged event. Also, if you want to notify you when any user changes (such as add, delete or sort), make sure your application hooks
IbindingList interface (DataView object implements this interface)
ListChanged event.
Typically, the data is not used to programmatically use the user interface. But use binding objects (usually
DataView) Change the data.
You can use the Microsoft Visual Studio .NET integration development environment (IDE) to bind controls to support when designing
Any class for the IComponent interface. You can also bind at runtime. Binding operations use two parameters: objects and properties.
The following code will
TextBox control and
DataGrid control Binds to the same
CurrencyManager and
DataView:
TextBox1.Databindings.add ("Text", DS, "Customers.customerid))
DataGrid1.datasource = DS
DataGrid1.datamember = "Customers" In addition, you can use the following code to bind to different
CurrencyManager and
DataView object:
TextBox1.Databindings.add ("Text", DS.Tables ("Customers"), "Customerid")
DataGrid1.datasource = DS.Tables ("Customers") The sample examples of the previous code show the same data. Editing and scrolling is not synchronized between the examples, but is synchronized in the example.
You can also traverse in the data binding syntax
DataRelation object. In the code below, the second
DataGrid Using Custord
Dataralation is displayed in the first one
ORDERS records for the current Customers record selected in DataGrid:
DataGrid1.datasource = DS
DataGrid1.DataMember = "Customers"
DataGrid2.DataSource = DS
DataGrid2.DataSource = "Customers.custord" To retrieve the foundation
CurrencyManager or
PropertyManager, please use the form
BindingContext properties. This will return forced to convert to
The appropriate manager of the BindingManagerBase base interface (you can convert the base class interface to the appropriate derived class):
Cm = ctype (Me.BindingContext (DS, "Customers"), CurrencyManager
CurrencyManager can pass
List attributes get a basic binding collection. If you know the derived type, you can force the returned object to the appropriate derived class:
DV = ctype (cm.list, dataview) 'okay if cm is bound to a dataview.
Al = ctype (cm.list, arraylist) 'okay if cm is bound to an arraylist. from
PropertyManager can pass
The Current property gains a basic binding object.
MyObject = ctype (PM.Current, MyClass) For more information on Windows Form Data Binding, see the topic of the following Microsoft Visual Studio .NET Help documents:
