///--------------------------------------------------------------------
/// <summary>
/// Obtains a TablePattern control pattern from an

/// <param name="targetControl">
/// The automation element of interest.

///--------------------------------------------------------------------
private TablePattern GetTablePattern(
AutomationElement targetControl)
{
TablePattern tablePattern = null;
try
{
tablePattern =
targetControl.GetCurrentPattern(
TablePattern.Pattern)
as TablePattern;
}
// Object doesn't support the
// GridPattern control pattern
catch (InvalidOperationException)
{
return null;
}
return tablePattern;
}

注解
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TablePatternIdentifiers等效字段。
模式标识符将传递给等 GetCurrentPattern 方法,以便从指定的 AutomationElement检索感兴趣的控件模式。
