示例
下面的代码示例演示如何使用 RefreshPropertiesAttribute 类指定属性的刷新模式 DataSource 。The following code example demonstrates using the RefreshPropertiesAttribute class to specify the refresh mode for a DataSource property. 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.
[Category("Data")]
[Description("Indicates the source of data for the control.")]
[RefreshProperties(RefreshProperties.Repaint)]
[AttributeProvider(typeof(IListSource))]
public object DataSource
{
get
{
return this.dataGridView1.DataSource;
}
set
{
this.dataGridView1.DataSource = value;
}
}
<Category("Data"), _
Description("Indicates the source of data for the control."), _
RefreshProperties(RefreshProperties.Repaint), _
AttributeProvider(GetType(IListSource))> _
Public Property DataSource() As Object
Get
Return Me.dataGridView1.DataSource
End Get
Set(ByVal value As Object)
Me.dataGridView1.DataSource = value
End Set
End Property
注解
RefreshPropertiesAttribute指示刷新控件时要使用的刷新模式的类型 PropertyGrid 。The RefreshPropertiesAttribute indicates the type of refresh mode to use when refreshing a PropertyGrid control.
构造函数
| RefreshPropertiesAttribute(RefreshProperties) |
初始化 RefreshPropertiesAttribute 类的新实例。Initializes a new instance of the RefreshPropertiesAttribute class. |
字段
| All |
指示在属性值更改时重新查询并刷新所有属性。Indicates that all properties are queried again and refreshed if the property value is changed. 此字段为只读。This field is read-only. |
| Default |
指示在该属性值更改时不刷新其他任何属性。Indicates that no other properties are refreshed if the property value is changed. 此字段为只读。This field is read-only. |
| Repaint |
指示在属性值更改时重新绘制所有属性。Indicates that all properties are repainted if the property value is changed. 此字段为只读。This field is read-only. |
属性
| RefreshProperties |
获取成员的刷新属性。Gets the refresh properties for the member. |
| 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) | |
| GetHashCode() |
返回此对象的哈希代码。Returns the hash code for this object. |
| GetType() |
获取当前实例的 Type。Gets the Type of the current instance. (继承自 Object) |
| IsDefaultAttribute() |
获取一个值,该值指示该特性的当前值是否为该特性的默认值。Gets a value indicating whether the current value of the attribute is the default value for the attribute. |
| 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. (继承自 Attribute) |
