注解

Windows 窗体包括内置的辅助功能支持,使你的应用程序能够使用具有辅助功能的客户端应用程序。Windows Forms includes built-in accessibility support that allows your application to work with accessibility client applications. 辅助功能客户端应用程序的示例包括屏幕弱视和审阅者实用程序、语音输入实用程序、屏幕键盘、备用输入设备和键盘增强实用程序。Examples of accessibility client applications include screen enlarger and reviewer utilities, voice input utilities, on-screen keyboards, alternative input devices, and keyboard enhancement utilities.

DataGridViewRow.DataGridViewRowAccessibleObject 类继承自 AccessibleObject 类,以便向具有辅助功能的客户端应用程序提供有关 DataGridViewRow 的信息。The DataGridViewRow.DataGridViewRowAccessibleObject class inherits from the AccessibleObject class to provide information about a DataGridViewRow to accessibility client applications. 每个表示 DataGridView 的可视部分的类(如 DataGridViewColumnHeaderCellDataGridViewRowHeaderCellDataGridViewRowDataGridViewCell)还包含从 AccessibleObject 继承以提供有关包含类的信息并代表可访问性执行操作的类客户端应用程序。Each class that represents a visual part of the DataGridView - such as DataGridViewColumnHeaderCell, DataGridViewRowHeaderCell, DataGridViewRow and DataGridViewCell - also contains a class that inherits from AccessibleObject to provide information about the containing class and perform actions on behalf of accessibility client applications.

在某些情况下,你将需要向具有辅助功能的客户端应用程序提供附加信息(例如 DataGridView 控件的名称或说明)。There are instances when you will want to provide additional information, such as the name or description of the DataGridView control, to accessibility client applications. 提供此附加信息的方法有两种。There are two ways of providing this additional information. 若要提供现有控件的有限辅助功能信息,请设置控件的 AccessibleNameAccessibleDescription 属性值,这些值将报告给具有辅助功能的客户端应用程序。To provide limited accessibility information for existing controls, set the control's AccessibleName and AccessibleDescription property values, which will be reported to accessibility client applications.

备注

只应在极少数情况下更改 AccessibleDefaultActionDescriptionAccessibleRole 属性值,例如,如果您将 DataGridView 显示为列表。You should change the AccessibleDefaultActionDescription and AccessibleRole property values only in rare situations, such as if you make a DataGridView look like a list.

有时,你可能需要更多的辅助功能信息或不同的辅助功能操作,才能包含在你的自定义 DataGridViewDataGridViewCell中。Occasionally, you might require more accessibility information or different accessibility actions to be included with your custom DataGridView or DataGridViewCell. 若要自定义可访问性,可以编写自己的类,该类派生自 DataGridView.DataGridViewAccessibleObjectDataGridViewCell.DataGridViewCellAccessibleObject 类,并重写 CreateAccessibilityInstance 方法。To customize accessibility, you can write your own class that derives from the DataGridView.DataGridViewAccessibleObject or DataGridViewCell.DataGridViewCellAccessibleObject classes and override the CreateAccessibilityInstance method. 例如,如果您要编写一个自定义行标题单元格来实现独特的自定义操作(例如单元中的特殊命中测试),则应创建一个继承自 DataGridViewRowHeaderCell.DataGridViewRowHeaderCellAccessibleObject 类的类并重写 CreateAccessibilityInstance 方法。For example, if you are writing a custom row header cell that implements unique custom actions, such as special hit testing within your cell, you should create a class that inherits from the DataGridViewRowHeaderCell.DataGridViewRowHeaderCellAccessibleObject class and override the CreateAccessibilityInstance method.

DataGridView 使用 AccessibleRole 值来定义数据表层次结构,从而公开其数据结构。The DataGridView exposes its data structure by using AccessibleRole values to define the data table hierarchy. 有关向 Microsoft Active Accessibility 公开数据表的详细信息,请参阅 MSDN library 中的 "通过 Microsoft Active Accessibility 公开数据表 https://msdn.microsoft.com/library"。For more information on exposing data tables to Microsoft Active Accessibility, see "Exposing Data Tables through Microsoft Active Accessibility" in the MSDN library at https://msdn.microsoft.com/library.
