ValuePattern.ValueProperty Field

Identifies the Value property.

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

public static readonly AutomationProperty ValueProperty

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

In the following example, a ValuePattern object obtained from a target control is passed into a function that retrieves the current ValuePattern property values.

/// <summary> 
/// Gets the current property values from target. 
/// </summary> 
/// <param name="valuePattern">
/// A ValuePattern control pattern obtained from  
/// an automation element representing a target control. 
/// </param> 
/// <param name="automationProperty">
/// The automation property of interest. 
/// </param> 
private object GetValueProperty(
    ValuePattern valuePattern,
    AutomationProperty automationProperty)
    if (valuePattern == null || automationProperty == null)
        throw new ArgumentNullException("Argument cannot be null.");

    if (automationProperty.Id ==
        return valuePattern.Current.Value;
    return null;
