ProvidePropertyAttribute Class
Specifies the name of the property that an implementer of IExtenderProvider offers to other components. This class cannot be inherited
Assembly: System (in System.dll)
When you mark a class with this attribute, you tell the code generator to create an extender property with the name you provide. The marked class must implement IExtenderProvider. As a result, the new property can be used by other components in a container.
Within the marked class, you must implement Get <name> and Set <name> methods. For example, if you mark a class with [ProvideProperty("PropertyName")], you must implement GetPropertyName and SetPropertyName methods. To specify that the new property will be an extender property, you must implement from IExtenderProvider, you must also implement a CanExtend method.
For more information, see Attributes Overview and Extending Metadata Using Attributes.
The following example marks MyClass with a ProvidePropertyAttribute that tells the compiler to create a property called MyProperty from the GetMyProperty and SetMyProperty methods.
<ProvideProperty("MyProperty", GetType(Control))> _ Public Class SampleClass Implements IExtenderProvider Protected ciMine As CultureInfo = Nothing ' Provides the Get portion of MyProperty. Public Function GetMyProperty(myControl As Control) As CultureInfo ' Insert code here. Return ciMine End Function 'GetMyProperty ' Provides the Set portion of MyProperty. Public Sub SetMyProperty(myControl As Control, value As String) ' Insert code here. End Sub 'SetMyProperty ' When you inherit from IExtenderProvider, you must implement the ' CanExtend method. Public Function CanExtend(target As [Object]) As Boolean Implements IExtenderProvider.CanExtend Return TypeOf target Is Control End Function 'CanExtend ' Insert additional code here. End Class
