Examples

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;
    }
    else
    {
        SelectionItemPattern.SelectionItemPatternInformation properties = pattern.Current;
        return properties.SelectionContainer;
    }
}

''' <summary>
''' Retrieves the selection container for a selection item.
''' </summary>
''' <param name="listItem">
''' An element that supports SelectionItemPattern.
''' </param>
Function GetListItemParent(ByVal listItem As AutomationElement) As AutomationElement
    If listItem Is Nothing Then
        Throw New ArgumentException()
    End If
    Dim pattern As SelectionItemPattern = _
        DirectCast(listItem.GetCurrentPattern(SelectionItemPattern.Pattern), SelectionItemPattern)
    If pattern Is Nothing Then
        Return Nothing
    Else
        Dim properties As SelectionItemPattern.SelectionItemPatternInformation = pattern.Current
        Return properties.SelectionContainer
    End If

End Function 'GetListItemParent

Remarks

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