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 DataSourceThe 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

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

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)

重写对象的 Equals 方法。Overrides the object's Equals method.

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 TypeGets 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)
_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).
