What control class property is used to set the tab order for an application's interface?

The TabIndex property is essential for establishing the order in which controls receive focus when the user navigates through the application using the Tab key. This feature greatly enhances user experience, particularly in forms and interfaces that utilize multiple input fields. By assigning a numerical value to the TabIndex property for each control, developers can dictate the sequence of focus—lower numbers receive focus first.

For instance, a control with a TabIndex of 0 will be focused before one with a TabIndex of 1. This provides a logical flow and allows users to move through the application in a predictable manner, making it easier for them to interact with the interface.

Other terms like TabOrder and TabSequence do not refer to recognized properties in the context of setting tab order. While TabStop is a property that determines whether a control can receive focus (it is either true or false), it does not establish the order of that focus amongst various controls. Therefore, the TabIndex property is the correct choice, as it serves the specific purpose of managing the tab navigation sequence in an application.
