ValuePattern.IsReadOnlyProperty Field

Identifies the IsReadOnly property.

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

Public Shared ReadOnly IsReadOnlyProperty As AutomationProperty

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

A control should have its IsEnabledProperty set to true and its IsReadOnlyProperty set to false before a client attempts a call to SetValue.

In the following example, a root element is passed to a function that returns a collection of UI 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="targetApp"> 
''' 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 targetApp As AutomationElement) As AutomationElementCollection
    If targetApp Is Nothing Then 
        Throw New ArgumentException("Root element cannot be null.")
    End If 

    Dim conditionIsReadOnly As New PropertyCondition( _
    ValuePattern.IsReadOnlyProperty, False)

    Return targetApp.FindAll(TreeScope.Descendants, conditionIsReadOnly)

End Function 'FindAutomationElement
