Properties
  Name Description
Public property Name Gets the name of the default binding property for the component to which the DefaultBindingPropertyAttribute is bound.
Public property TypeId When implemented in a derived class, gets a unique identifier for this Attribute. (Inherited from Attribute.)

Methods
  Name Description
Public method Equals Determines whether the specified Object is equal to the current DefaultBindingPropertyAttribute instance. (Overrides Attribute.Equals(Object).)
Protected method Finalize Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.)
Public method GetHashCode Returns the hash code for this instance. (Overrides Attribute.GetHashCode().)
Public method GetType Gets the Type of the current instance. (Inherited from Object.)
Public method IsDefaultAttribute When 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 Match When overridden in a derived class, returns a value that indicates whether this instance equals a specified object. (Inherited from Attribute.)
Protected method MemberwiseClone Creates a shallow copy of the current Object. (Inherited from Object.)
Public method ToString Returns a string that represents the current object. (Inherited from Object.)

Fields
  Name Description
Public field Static member Default Represents the default value for the DefaultBindingPropertyAttribute class.

Explicit Interface Implementations
  Name Description
Explicit interface implemetation Private method _Attribute.GetIDsOfNames Maps a set of names to a corresponding set of dispatch identifiers. (Inherited from Attribute.)
Explicit interface implemetation Private method _Attribute.GetTypeInfo Retrieves 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 _Attribute.GetTypeInfoCount Retrieves the number of type information interfaces that an object provides (either 0 or 1). (Inherited from Attribute.)
Explicit interface implemetation Private method _Attribute.Invoke Provides access to properties and methods exposed by an object. (Inherited from Attribute.)

Remarks

The DefaultBindingPropertyAttribute is specified at the class level. It can be inherited and does not allow multiple attributes on the same class.

Examples

The following code example demonstrates using the DefaultBindingPropertyAttribute class to specify the default property for data binding. For a full code listing, see How to: Apply Attributes in Windows Forms Controls.
