SelectionPattern.Pattern Field

Identifies the SelectionPatterncontrol pattern.

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

public static readonly AutomationPattern Pattern
public static final AutomationPattern Pattern
public static final var Pattern : AutomationPattern
Not applicable.

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

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 SelectionPatterncontrol pattern is obtained from an AutomationElement.

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

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

    return selectionPattern;
}
