GridItemPattern.ColumnSpanProperty 字段

定义

命名空间:

System.Windows.Automation

程序集:

UIAutomationClient.dll

标识 ColumnSpan 属性。

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

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

 staticval mutable ColumnSpanProperty : System.Windows.Automation.AutomationProperty

Public Shared ReadOnly ColumnSpanProperty As AutomationProperty 

字段值

AutomationProperty

示例

在下面的示例中 GridItemPattern ，从目标控件获取的对象将传递到检索当前 GridItemPattern 属性值的函数中。

此标识符由UI 自动化客户端应用程序使用。 UI 自动化提供程序应使用 中的GridItemPatternIdentifiers等效字段。
