FilterUIHintAttribute 类

定义

注意

This attribute is no longer in use and will be ignored if applied.

表示用于指定列的筛选行为的特性。Represents an attribute that is used to specify the filtering behavior for a column.

public ref class FilterUIHintAttribute sealed : Attribute
[System.AttributeUsage(System.AttributeTargets.Field | System.AttributeTargets.Property, AllowMultiple=false)]
[System.Obsolete("This attribute is no longer in use and will be ignored if applied.")]
public sealed class FilterUIHintAttribute : Attribute
[System.AttributeUsage(System.AttributeTargets.Field | System.AttributeTargets.Property, AllowMultiple=false)]
public sealed class FilterUIHintAttribute : Attribute
[<System.AttributeUsage(System.AttributeTargets.Field | System.AttributeTargets.Property, AllowMultiple=false)>]
[<System.Obsolete("This attribute is no longer in use and will be ignored if applied.")>]
type FilterUIHintAttribute = class
    inherit Attribute
[<System.AttributeUsage(System.AttributeTargets.Field | System.AttributeTargets.Property, AllowMultiple=false)>]
type FilterUIHintAttribute = class
    inherit Attribute
Public NotInheritable Class FilterUIHintAttribute
Inherits Attribute

示例

下面的示例演示如何替换 product 实体上的默认筛选器。The following example shows how to replace default filters on the product entity.

MetadataType(typeof(Product_MD))]  
public partial class Product {  
    private class Product_MD {  
        [FilterUIHint("MultiForeignKey")]  
        public object Category { get; set; }  
        [FilterUIHint("BooleanRadio")]  
        public object Discontinued { get; set; }  
    }  
}  
<MetadataType(GetType(Product_MD))>  _  
Public Class Product  
    Private Class Product_MD  
        <FilterUIHint("MultiForeignKey")>  _  
        Public Property Category As Object  
        End Property  

        <FilterUIHint("BooleanRadio")>  _  
        Public Property Discontinued As Object  
        End Property  

    End Class  
End Class  

构造函数

FilterUIHintAttribute(String)

通过使用筛选器 UI 提示来初始化 FilterUIHintAttribute 类的新实例。Initializes a new instance of the FilterUIHintAttribute class by using the filter UI hint.

FilterUIHintAttribute(String, String)

通过使用筛选器 UI 提示和表示层名称来初始化 FilterUIHintAttribute 类的新实例。Initializes a new instance of the FilterUIHintAttribute class by using the filter UI hint and presentation layer name.

FilterUIHintAttribute(String, String, Object[])

通过使用筛选器 UI 提示、表示层名称和控件参数来初始化 FilterUIHintAttribute 类的新实例。Initializes a new instance of the FilterUIHintAttribute class by using the filter UI hint, presentation layer name, and control parameters.

属性

ControlParameters

获取用作控件的构造函数中的参数的名称/值对。Gets the name/value pairs that are used as parameters in the control's constructor.

FilterUIHint

获取用于筛选的控件的名称。Gets the name of the control to use for filtering.

PresentationLayer

获取支持此控件的表示层的名称。Gets the name of the presentation layer that supports this control.

TypeId

返回此特性实例的唯一标识符。Returns the unique identifier for this attribute instance.

TypeId

在派生类中实现时,获取此 Attribute 的唯一标识符。When implemented in a derived class, gets a unique identifier for this Attribute.

(继承自 Attribute)

方法

Equals(Object)

返回一个值,该值指示此特性实例是否与指定的对象相等。Returns a value that indicates whether this attribute instance is equal to a specified object.

GetHashCode()

返回此特性实例的哈希代码。Returns the hash code for this attribute instance.

GetType()

获取当前实例的 TypeGets the Type of the current instance.

(继承自 Object)
IsDefaultAttribute()

在派生类中重写时,指示此实例的值是否是派生类的默认值。When overridden in a derived class, indicates whether the value of this instance is the default value for the derived class.

(继承自 Attribute)
Match(Object)

当在派生类中重写时,返回一个指示此实例是否等于指定对象的值。When overridden in a derived class, returns a value that indicates whether this instance equals a specified object.

(继承自 Attribute)
MemberwiseClone()

创建当前 Object 的浅表副本。Creates a shallow copy of the current Object.

(继承自 Object)
ToString()

返回表示当前对象的字符串。Returns a string that represents the current object.

(继承自 Object)

显式接口实现

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

将一组名称映射为对应的一组调度标识符。Maps a set of names to a corresponding set of dispatch identifiers.

(继承自 Attribute)
_Attribute.GetTypeInfo(UInt32, UInt32, IntPtr)

检索对象的类型信息,然后可以使用该信息获取接口的类型信息。Retrieves the type information for an object, which can be used to get the type information for an interface.

(继承自 Attribute)
_Attribute.GetTypeInfoCount(UInt32)

检索对象提供的类型信息接口的数量(0 或 1)。Retrieves the number of type information interfaces that an object provides (either 0 or 1).

(继承自 Attribute)
_Attribute.Invoke(UInt32, Guid, UInt32, Int16, IntPtr, IntPtr, IntPtr, IntPtr)

提供对某一对象公开的属性和方法的访问。Provides access to properties and methods exposed by an object.
