ComplexBindingPropertiesAttribute 类

定义

指定一个组件的数据源和数据成员属性,该组件支持复杂数据绑定。Specifies the data source and data member properties for a component that supports complex data binding. 此类不能被继承。This class cannot be inherited.

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

属性

示例

下面的代码示例演示如何ComplexBindingPropertiesAttribute使用标识控件的DataSourceDataMember属性用于数据绑定。The following code example demonstrates using ComplexBindingPropertiesAttribute to identify a control's DataSource and DataMember properties for data binding. 有关完整的代码清单, 请参阅如何:在 Windows 窗体控件中应用特性。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

注解

用于指定用于复杂数据绑定的属性, 例如System.Collections.IList基于的绑定。 ComplexBindingPropertiesAttributeThe ComplexBindingPropertiesAttribute is used to specify the properties used with complex data binding, such as binding based on System.Collections.IList.

特性ComplexBindingPropertiesAttribute是在类级别指定的。The ComplexBindingPropertiesAttribute attribute is specified at the class level. 它是可继承的, 不允许在同一个类中具有多个属性。It is inheritable and does not allow multiple attributes on the same class.

控件既可以支持简单绑定, DefaultBindingPropertyAttribute还可以支持复杂绑定。A control can support both simple binding, with DefaultBindingPropertyAttribute, as well as complex binding.
