AutomationElement.GetCurrentPattern Method

Retrieves the specified pattern object on this AutomationElement.

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

public Object GetCurrentPattern (
	AutomationPattern pattern
public Object GetCurrentPattern (
	AutomationPattern pattern
public function GetCurrentPattern (
	pattern : AutomationPattern
) : Object
Not applicable.



The identifier of the pattern to retrieve.

Return Value

The pattern object, if the specified pattern is currently supported by the AutomationElement.

Exception typeCondition


The pattern is not supported by the element.


The UI for the AutomationElement no longer exists.

GetCurrentPattern gets the specified pattern based on its availability at the time of the call.

For some forms of UI, this method will incur cross-process performance overhead. Applications can concentrate overhead by caching patterns and then retrieving them by using GetCachedPattern.

The following example shows how to use this method to retrieve a SelectionItemPattern, which is then used to select an item in a list box.

/// <summary>
/// Sets the focus to a list and selects a string item in that list.
/// </summary>
/// <param name="listElement">The list element.</param>
/// <param name="itemText">The text to select.</param>
/// <remarks>
/// This deselects any currently selected items. To add the item to the current selection 
/// in a multiselect list, use AddToSelection instead of Select.
/// </remarks>
public void SelectListItem(AutomationElement listElement, String itemText)
    if ((listElement == null) || (itemText == ""))
        throw new ArgumentException("Argument cannot be null or empty.");
    Condition cond = new PropertyCondition(
        AutomationElement.NameProperty, itemText, PropertyConditionFlags.IgnoreCase);
    AutomationElement elementItem = listElement.FindFirst(TreeScope.Children, cond);
    if (elementItem != null)
        SelectionItemPattern pattern;
            pattern = elementItem.GetCurrentPattern(SelectionItemPattern.Pattern) as SelectionItemPattern;
        catch (InvalidOperationException ex)
            Console.WriteLine(ex.Message);  // Most likely "Pattern not supported."


For often-repeated tasks such as the one in the example, it would be more efficient to cache the pattern and use GetCachedPattern.
