IRangeValueProvider Interface

  • Reference

Definition

Namespace:
Microsoft.UI.Xaml.Automation.Provider
Edit

Exposes methods and properties to support access by a Microsoft UI Automation client to controls that can be set to a value within a range. Implement this interface in order to support the capabilities that an automation client requests with a AutomationPeer.GetPattern call and PatternInterface.RangeValue.

public interface class IRangeValueProvider
/// [Windows.Foundation.Metadata.ContractVersion(Microsoft.UI.Xaml.WinUIContract, 65536)]
/// [Windows.Foundation.Metadata.Guid(1922753556, 7823, 20512, 130, 187, 187, 87, 77, 20, 95, 216)]
struct IRangeValueProvider
[Windows.Foundation.Metadata.ContractVersion(typeof(Microsoft.UI.Xaml.WinUIContract), 65536)]
[Windows.Foundation.Metadata.Guid(1922753556, 7823, 20512, 130, 187, 187, 87, 77, 20, 95, 216)]

Remarks

This pattern has guidelines and conventions that aren't fully documented here. For more info on what this pattern is for, see RangeValue Control Pattern.

IRangeValueProvider is implemented by the existing Windows Runtime class RangeBaseAutomationPeer. This is the base class for peers for Slider, ScrollBar and ProgressBar. ProgressBarAutomationPeer adds an override such that it won't support the pattern if the value of IsIndeterminate on the owner control is false.

Use RangeValuePatternIdentifiers if you want to reference the IRangeValueProvider pattern properties from control code when you fire automation events or call AutomationPeer.RaisePropertyChangedEvent.
