UI Automation Support for the Spinner Control Type
This topic provides information about UI Automation support for the Spinner control type. In UI Automation, a control type is a set of conditions that a control must meet in order to use the ControlTypeProperty property. The conditions include specific guidelines for UI Automation tree structure, UI Automation property values and control patterns.
Spinner controls are used to select from a domain of items or a range of numbers.
The following sections define the required UI Automation tree structure, properties, control patterns, and events for the Spinner control type. The UI Automation requirements apply to all spinner controls, whether Windows Presentation Foundation (WPF), Win32, or Windows Forms.
This topic contains the following sections.
- Required UI Automation Tree Structure
- Required UI Automation Properties

Required UI Automation Tree Structure
The following table depicts the control view and the content view of the UI Automation tree that pertain to spinner controls when they support the Range Value and Selection control patterns and describes what can be contained in each view. For more information on the UI Automation tree, see UI Automation Tree Overview.
Range Value control pattern
| Control View | Content View |
|---|---|

Selection control pattern
| Control View | Content View |

To ensure that the two buttons in the control view subtree can be distinguished by automated test tools, assign the SmallIncrement or SmallDecrement AutomationId as appropriate.
