ComplexBindingPropertiesAttribute Class

Definition

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

public ref class ComplexBindingPropertiesAttribute sealed : Attribute
[System.AttributeUsage(System.AttributeTargets.Class)]
public sealed class ComplexBindingPropertiesAttribute : Attribute
[<System.AttributeUsage(System.AttributeTargets.Class)>]
type ComplexBindingPropertiesAttribute = class
    inherit Attribute
Public NotInheritable Class ComplexBindingPropertiesAttribute
Inherits Attribute

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(typeof(UserControl))]
[ToolboxItem("System.Windows.Forms.Design.AutoSizeToolboxItem,System.Design")]
public class AttributesDemoControl : UserControl
{
' 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")> _
Public Class AttributesDemoControl
    Inherits UserControl

Remarks

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 Attributes.

Constructors

ComplexBindingPropertiesAttribute()

Initializes a new instance of the ComplexBindingPropertiesAttribute class using no parameters.

ComplexBindingPropertiesAttribute(String, String)

Initializes a new instance of the ComplexBindingPropertiesAttribute class using the specified data source and data member.

ComplexBindingPropertiesAttribute(String)

Initializes a new instance of the ComplexBindingPropertiesAttribute class using the specified data source.

Fields

Default

Represents the default value for the ComplexBindingPropertiesAttribute class.

Properties

DataMember

Gets the name of the data member property for the component to which the ComplexBindingPropertiesAttribute is bound.

DataSource

Gets the name of the data source property for the component to which the ComplexBindingPropertiesAttribute is bound.

TypeId

When implemented in a derived class, gets a unique identifier for this Attribute.

(Inherited from Attribute)

Methods

Equals(Object)

Determines whether the specified Object is equal to the current ComplexBindingPropertiesAttribute instance.

GetHashCode()

Returns the hash code for this instance.

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(Object)

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

_Attribute.GetIDsOfNames(Guid, IntPtr, UInt32, UInt32, IntPtr)

Maps a set of names to a corresponding set of dispatch identifiers.

(Inherited from Attribute)
_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)
_Attribute.GetTypeInfoCount(UInt32)

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

(Inherited from Attribute)
_Attribute.Invoke(UInt32, Guid, UInt32, Int16, IntPtr, IntPtr, IntPtr, IntPtr)

Provides access to properties and methods exposed by an object.
