UI Automation Support for the Slider Control Type
This topic provides information about UI Automation support for the Slider 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 types.
The Slider control is a composite control with buttons that enable a user with a mouse to set a numerical range or select from a set of items.
The following sections define the required UI Automation tree structure, properties, control patterns, and events for the Slider control type. The UI Automation requirements apply to all slider controls, whether Windows Presentation Foundation (WPF), Win32, or Windows Forms.
