SelectionItemPattern.Pattern Field

Identifies the SelectionItemPattern control pattern.

Namespace:  System.Windows.Automation
Assembly:  UIAutomationClient (in UIAutomationClient.dll)

public static readonly AutomationPattern Pattern

This identifier is used by UI Automation client applications. UI Automation providers should use the equivalent field in SelectionItemPatternIdentifiers.

The pattern identifier is passed to methods such as GetCurrentPattern to retrieve the control pattern of interest from the specified AutomationElement.

In the following example, a SelectionItemPattern control pattern is obtained from an AutomationElement.


///--------------------------------------------------------------------
/// <summary>
/// Obtains a SelectionItemPattern control pattern from an 
/// automation element.
/// </summary>
/// <param name="targetControl">
/// The automation element of interest.
/// </param>
/// <returns>
/// A SelectionItemPattern object.
/// </returns>
///--------------------------------------------------------------------
private SelectionItemPattern GetSelectionItemPattern(
    AutomationElement targetControl)
{
    SelectionItemPattern selectionItemPattern = null;

    try
    {
        selectionItemPattern =
            targetControl.GetCurrentPattern(
            SelectionItemPattern.Pattern)
            as SelectionItemPattern;
    }
    // Object doesn't support the 
    // SelectionItemPattern control pattern
    catch (InvalidOperationException)
    {
        return null;
    }

    return selectionItemPattern;
}
