RangeValuePattern.IsReadOnlyProperty Field

Identifies the IsReadOnly property.

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

public static readonly AutomationProperty IsReadOnlyProperty

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

In the following example, a root element is passed to a function that returns a collection of AutomationElements 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 AutomationElementCollection FindAutomationElement(
    AutomationElement targetApp)
{
    if (targetApp == null)
    {
        throw new ArgumentException("Root element cannot be null.");
    }

    PropertyCondition conditionIsReadOnly =
        new PropertyCondition(
        RangeValuePattern.IsReadOnlyProperty, false);

    return targetApp.FindAll(
        TreeScope.Descendants, conditionIsReadOnly);
}
