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.

[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.")>]

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 Type。Gets 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) |
