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 GetPattern call and PatternInterface.RangeValue.
The IRangeValueProvider interface has these types of members:
The IRangeValueProvider interface has these methods. It also inherits methods from the Object class.
|SetValue||Sets the value of the control.|
The IRangeValueProvider interface has these properties.
|Read-only||Gets a value that indicates whether the value of a control is read-only.|
|Read-only||Gets the value that is added to or subtracted from the Value property when a large change is made, such as with the PAGE DOWN key.|
|Read-only||Gets the maximum range value that is supported by the control.|
|Read-only||Gets the minimum range value that is supported by the control.|
|Read-only||Gets the value that is added to or subtracted from the Value property when a small change is made, such as with an arrow key.|
|Read-only||Gets the value of the control.|
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.
