TogglePattern.ToggleStateProperty Field

Identifies the ToggleStateproperty.

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

'Declaration
Public Shared ReadOnly ToggleStateProperty As AutomationProperty

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

An AutomationElement must cycle through its ToggleState in this order: On, Off and, if supported, Indeterminate.

In the following example, a root element is passed to a function that returns a collection of automation elements that are descendants of the root and satisfy a set of property conditions.

'''-------------------------------------------------------------------- 
''' <summary> 
''' Finds all automation elements that satisfy  
''' the specified condition(s). 
''' </summary> 
''' <param name="rootElement"> 
''' The automation element from which to start searching. 
''' </param> 
''' <returns> 
''' A collection of automation elements satisfying  
''' the specified condition(s). 
''' </returns> 
'''-------------------------------------------------------------------- 
Private Function FindAutomationElement( _
ByVal rootElement As AutomationElement) As AutomationElementCollection
    If rootElement Is Nothing Then 
        Throw New ArgumentException("Root element cannot be null.")
    End If 

    Dim conditionOn As New PropertyCondition( _
    TogglePattern.ToggleStateProperty, ToggleState.On)

    Dim conditionIndeterminate As New PropertyCondition( _
    TogglePattern.ToggleStateProperty, ToggleState.Indeterminate)

    ' Use any combination of the preceding condtions to  
    ' find the control(s) of interest 
    Dim condition As OrCondition = _
    New OrCondition(conditionOn, conditionIndeterminate)

    Return rootElement.FindAll(TreeScope.Descendants, condition)

End Function 'FindAutomationElement
