ComplexBindingPropertiesAttribute Class

Definition

Namespace:

System.ComponentModel

Assembly:

System.ComponentModel.TypeConverter.dll

Source:

ComplexBindingPropertiesAttribute.cs

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

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)
