public ref class ControlValuePropertyAttribute sealed : Attribute

NameDescription
System_CAPS_pubmethodControlValuePropertyAttribute(String^)

Initializes a new instance of the ControlValuePropertyAttribute class using the specified property name.

System_CAPS_pubmethodControlValuePropertyAttribute(String^, Object^)

Initializes a new instance of the ControlValuePropertyAttribute class using the specified property name and default value.

System_CAPS_pubmethodControlValuePropertyAttribute(String^, Type^, String^)

Initializes a new instance of the ControlValuePropertyAttribute class using the specified property name and default value. The default value is also converted to the specified data type.

NameDescription
System_CAPS_pubpropertyDefaultValue

Gets the default value for the default property of a control.

System_CAPS_pubpropertyName

Gets the default property for a control.

System_CAPS_pubpropertyTypeId

When implemented in a derived class, gets a unique identifier for this Attribute.(Inherited from Attribute.)

NameDescription
System_CAPS_pubmethodEquals(Object^)

Determines whether the current instance of the ControlValuePropertyAttribute object is equal to the specified object.(Overrides Attribute::Equals(Object^).)

System_CAPS_pubmethodGetHashCode()

Returns the hash code for this instance.(Overrides Attribute::GetHashCode().)

System_CAPS_pubmethodGetType()

Gets the Type of the current instance.(Inherited from Object.)

System_CAPS_pubmethodIsDefaultAttribute()

When overridden in a derived class, indicates whether the value of this instance is the default value for the derived class.(Inherited from Attribute.)

System_CAPS_pubmethodMatch(Object^)

When overridden in a derived class, returns a value that indicates whether this instance equals a specified object.(Inherited from Attribute.)

System_CAPS_pubmethodToString()

Returns a string that represents the current object.(Inherited from Object.)

NameDescription
System_CAPS_pubinterfaceSystem_CAPS_privmethod_Attribute::GetIDsOfNames(Guid%, IntPtr, UInt32, UInt32, IntPtr)

Maps a set of names to a corresponding set of dispatch identifiers.(Inherited from Attribute.)

System_CAPS_pubinterfaceSystem_CAPS_privmethod_Attribute::GetTypeInfo(UInt32, UInt32, IntPtr)

Retrieves the type information for an object, which can be used to get the type information for an interface.(Inherited from Attribute.)

System_CAPS_pubinterfaceSystem_CAPS_privmethod_Attribute::GetTypeInfoCount(UInt32%)

Retrieves the number of type information interfaces that an object provides (either 0 or 1).(Inherited from Attribute.)

System_CAPS_pubinterfaceSystem_CAPS_privmethod_Attribute::Invoke(UInt32, Guid%, UInt32, Int16, IntPtr, IntPtr, IntPtr, IntPtr)

Provides access to properties and methods exposed by an object.(Inherited from Attribute.)

When defining a ControlParameter object, you typically bind a control's property to a parameter by setting both the ControlID and PropertyName properties. If the PropertyName property is not set, a default property is used. The ControlValuePropertyAttribute attribute is applied to a control to specify its default property that a ControlParameter object binds to at run time.

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

For a list of initial property values for an instance of the ControlValuePropertyAttribute class, see the ControlValuePropertyAttribute constructor.

The following code example demonstrates how to apply a ControlValuePropertyAttribute attribute that specifies a default property and value to a custom control.
