The DefaultTypeArgumentAttribute type exposes the following members.
Constructors
| Name | Description | |
|---|---|---|
|
DefaultTypeArgumentAttribute | Creates an instance of the DefaultTypeArgumentAttribute class with a specified default type. |
Properties
| Name | Description | |
|---|---|---|
|
Type | Gets the type stored by the DefaultTypeArgumentAttribute. |
|
TypeId | When implemented in a derived class, gets a unique identifier for this Attribute. (Inherited from Attribute.) |
Methods
| Name | Description | |
|---|---|---|
|
Equals | Infrastructure. Returns a value that indicates whether this instance is equal to a specified object. (Inherited from Attribute.) |
|
Finalize | Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.) |
|
GetHashCode | Returns the hash code for this instance. (Inherited from Attribute.) |
|
GetType | Gets the Type of the current instance. (Inherited from Object.) |
|
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.) |
|
Match | When overridden in a derived class, returns a value that indicates whether this instance equals a specified object. (Inherited from Attribute.) |
|
MemberwiseClone | Creates a shallow copy of the current Object. (Inherited from Object.) |
|
ToString | Returns a string that represents the current object. (Inherited from Object.) |
Explicit Interface Implementations
| Name | Description | |
|---|---|---|
|
_Attribute.GetIDsOfNames | Maps a set of names to a corresponding set of dispatch identifiers. (Inherited from Attribute.) |
|
_Attribute.GetTypeInfo | Retrieves the type information for an object, which can be used to get the type information for an interface. (Inherited from Attribute.) |
|
_Attribute.GetTypeInfoCount | Retrieves the number of type information interfaces that an object provides (either 0 or 1). (Inherited from Attribute.) |
|
_Attribute.Invoke | Provides access to properties and methods exposed by an object. (Inherited from Attribute.) |
Remarks
Setting this attribute provides a default type for an element when dropped from the toolbox onto the designer surface. Note that while a default can be set, the designer is required to provide a mechanism to change the type argument if that is required functionality.
