Instances of this type identify specific control patterns. For example, the DockPattern.Pattern field identifies the DockPattern control pattern.

The following example displays the ProgrammaticName of patterns supported by an AutomationElement.

The following example shows how to request a specific pattern.

/// <summary>
/// Retrieves the selection container for a selection item.
/// </summary>
/// <param name="listItem">
/// An element that supports SelectionItemPattern.
/// </param>
AutomationElement GetListItemParent(AutomationElement listItem)
    if (listItem == null) throw new ArgumentException();
    SelectionItemPattern pattern = listItem.GetCurrentPattern(SelectionItemPattern.Pattern) as SelectionItemPattern;
    if (pattern == null)
        return null;
        SelectionItemPattern.SelectionItemPatternInformation properties = pattern.Current;
        return properties.SelectionContainer;
