Field Value

Examples

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 AutomationElementCollection FindAutomationElement(
 AutomationElement targetApp)
{
 if (targetApp == null)
 {
 throw new ArgumentException("Root element cannot be null.");
 }

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

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

Private Function FindAutomationElement( _

 Return targetApp.FindAll(TreeScope.Descendants, conditionIsReadOnly)

End Function 'FindAutomationElement

Remarks

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.
