ComplexBindingPropertiesAttribute Class

Specifies the data source and data member properties for a component that supports complex data binding. This class cannot be inherited.

System.Object
  System.Attribute
    System.ComponentModel.ComplexBindingPropertiesAttribute

Namespace:  System.ComponentModel
Assembly:  System (in System.dll)

[AttributeUsageAttribute(AttributeTargets.Class)]
public sealed class ComplexBindingPropertiesAttribute : Attribute

The ComplexBindingPropertiesAttribute type exposes the following members.

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

  NameDescription
Public propertyDataMemberGets the name of the data member property for the component to which the ComplexBindingPropertiesAttribute is bound.
Public propertyDataSourceGets the name of the data source property for the component to which the ComplexBindingPropertiesAttribute is bound.
Public propertyTypeIdWhen implemented in a derived class, gets a unique identifier for this Attribute. (Inherited from Attribute.)

  NameDescription
Public methodEqualsDetermines whether the specified Object is equal to the current ComplexBindingPropertiesAttribute instance. (Overrides Attribute.Equals(Object).)
Public methodGetHashCodeReturns the hash code for this instance. (Overrides Attribute.GetHashCode().)
Public methodGetTypeGets the Type of the current instance. (Inherited from Object.)
Public methodIsDefaultAttributeWhen overridden in a derived class, indicates whether the value of this instance is the default value for the derived class. (Inherited from Attribute.)
Public methodMatchWhen overridden in a derived class, returns a value that indicates whether this instance equals a specified object. (Inherited from Attribute.)
Public methodToStringReturns a string that represents the current object. (Inherited from Object.)

  NameDescription
Explicit interface implemetationPrivate method_Attribute.GetIDsOfNamesMaps a set of names to a corresponding set of dispatch identifiers. (Inherited from Attribute.)
Explicit interface implemetationPrivate method_Attribute.GetTypeInfoRetrieves the type information for an object, which can be used to get the type information for an interface. (Inherited from Attribute.)
Explicit interface implemetationPrivate method_Attribute.GetTypeInfoCountRetrieves the number of type information interfaces that an object provides (either 0 or 1). (Inherited from Attribute.)
Explicit interface implemetationPrivate method_Attribute.InvokeProvides access to properties and methods exposed by an object. (Inherited from Attribute.)

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

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.

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.
