The ComplexBindingPropertiesAttribute type exposes the following members.

Constructors
  NameDescription
Public method ComplexBindingPropertiesAttributeInitializes a new instance of the ComplexBindingPropertiesAttribute class using no parameters.
Public method ComplexBindingPropertiesAttribute(String)Initializes a new instance of the ComplexBindingPropertiesAttribute class using the specified data source.
Public method ComplexBindingPropertiesAttribute(String, String)Initializes a new instance of the ComplexBindingPropertiesAttribute class using the specified data source and data member.

Properties
  NameDescription
Public property DataMemberGets the name of the data member property for the component to which the ComplexBindingPropertiesAttribute is bound.
Public property DataSourceGets the name of the data source property for the component to which the ComplexBindingPropertiesAttribute is bound.
Public property TypeIdWhen implemented in a derived class, gets a unique identifier for this Attribute. (Inherited from Attribute.)
Top
Methods
  NameDescription
Public method EqualsDetermines whether the specified Object is equal to the current ComplexBindingPropertiesAttribute instance. (Overrides AttributeEquals(Object).)
Public method GetHashCodeReturns the hash code for this instance. (Overrides AttributeGetHashCode.)
Public method GetTypeGets the Type of the current instance. (Inherited from Object.)
Public method IsDefaultAttributeWhen overridden in a derived class, indicates whether the value of this instance is the default value for the derived class. (Inherited from Attribute.)
Public method MatchWhen overridden in a derived class, returns a value that indicates whether this instance equals a specified object. (Inherited from Attribute.)
Public method ToStringReturns a string that represents the current object. (Inherited from Object.)
Top
Fields
  NameDescription
Public field Static member DefaultRepresents the default value for the ComplexBindingPropertiesAttribute class.

Explicit Interface Implementations
  NameDescription
Explicit interface implemetation Private method _AttributeGetIDsOfNamesMaps a set of names to a corresponding set of dispatch identifiers. (Inherited from Attribute.)
Explicit interface implemetation Private method _AttributeGetTypeInfoRetrieves the type information for an object, which can be used to get the type information for an interface. (Inherited from Attribute.)
Explicit interface implemetation Private method _AttributeGetTypeInfoCountRetrieves the number of type information interfaces that an object provides (either 0 or 1). (Inherited from Attribute.)
Explicit interface implemetation Private method _AttributeInvokeProvides access to properties and methods exposed by an object. (Inherited from Attribute.)

Remarks

The ComplexBindingPropertiesAttribute is used to specify the properties used with complex data binding, such as binding based on System.CollectionsIList.

The ComplexBindingPropertiesAttribute attribute is specified at the class level. It is inheritable and does not allow multiple attributes on the same class.

A control can support both simple binding, with DefaultBindingPropertyAttribute, as well as complex binding.

For more information about using attributes, see Extending Metadata Using Attributes.

Examples

The following code example demonstrates using ComplexBindingPropertiesAttribute to identify a control's DataSource and DataMember properties for data binding. For a full code listing, see How to: Apply Attributes in Windows Forms Controls.

' This control demonstrates a simple logging capability. 
<ComplexBindingProperties("DataSource", "DataMember"), _
DefaultBindingProperty("TitleText"), _
DefaultEvent("ThresholdExceeded"), _
DefaultProperty("Threshold"), _
HelpKeywordAttribute(GetType(UserControl)), _
ToolboxItem("System.Windows.Forms.Design.AutoSizeToolboxItem,System.Design")> _
