TablePattern.RowOrColumnMajorProperty 字段

定义

命名空间:

System.Windows.Automation

程序集:

UIAutomationClient.dll

标识 RowOrColumnMajor 属性。

public: static initonly System::Windows::Automation::AutomationProperty ^ RowOrColumnMajorProperty;

public static readonly System.Windows.Automation.AutomationProperty RowOrColumnMajorProperty;

 staticval mutable RowOrColumnMajorProperty : System.Windows.Automation.AutomationProperty

Public Shared ReadOnly RowOrColumnMajorProperty As AutomationProperty 

字段值

AutomationProperty

示例

在下面的示例中，将根元素传递给一个函数，该函数返回作为根子代并满足一组属性条件的对象集合 AutomationElement 。 此示例检索 AutomationElement支持 TablePattern 的 ，其中 为 RowOrColumnMajorPropertyIndeterminate 或 ColumnMajor。
