Public Property UseDirectXPaint As DefaultBoolean

Property Value

Type	Default	Description
DefaultBoolean	Default	A DefaultBoolean enumerator value that specifies whether or not this control employs the DirectX Hardware Acceleration. The DefaultBoolean.Default value is equivalent to DefaultBoolean.True if the static WindowsFormsSettings.ForceDirectXPaint method was called, or to DefaultBoolean.False otherwise.

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

You can also call the WindowsFormsSettings.ForceDirectXPaint method at the application’s startup to enable the DirectX Hardware Acceleration for all compatible DevExpress controls in the application.

Note

Only modify the UseDirectXPaint setting before the control’s handle is created. For instance, you can do this at design time, or in the form’s constructor.
