public static DefaultBoolean UseUIAutomation { get; set; }

VB.NET

Public Shared Property UseUIAutomation As DefaultBoolean

Property Value

Type	Description
DefaultBoolean	true if DevExpress controls should use UIAutomation patterns; otherwise, false.

Available values:

Name	Description
True	true. DefaultBoolean.True has a constant value of 0, while the standard true value corresponds to a value of 1. In Visual Basic, do not use implicit conversion of Boolean values to DefaultBoolean, and vice versa, as the conversion may produce incorrect results.
False	false. DefaultBoolean.False has a constant value of 1, while the standard false value corresponds to a value of 0. In Visual Basic, do not use implicit conversion of Boolean values to DefaultBoolean, and vice versa, as the conversion may produce incorrect results.
Default	The default behavior determined by the control’s logic.

Remarks

When the UseUIAutomation property is set to DefaultBoolean.True, most commonly-used DevExpress controls support UIAutomation patterns recommended by Microsoft (see this topic for more details: Control Types and Their Supported Control Patterns).
