Property Value

Type	Description
Nullable<Boolean>	true, to use DirectX; false, to use GDI+; null to use the default engine. The default engine is DirectX if the Use DirectX option is enabled in the Project settings; otherwise, the default engine is GDI+.

Property Paths

You can access this nested property as listed below:

Library	Object Type	Path to UseDirectX
WinForms Controls	OverlayWindowOptions	.Default .UseDirectX
XAF: Cross-Platform .NET App UI & Web API	DefaultOverlayFormOptions	.Options .UseDirectX

Remarks

You can enable the Use DirectX option in the Project Settings to use DirectX Hardware Acceleration for all compatible DevExpress controls in the application.

The UseDirectX property allows you to specify the draw engine for Overlay Forms only. This property value takes priority over the global option specified in the Project Settings. If this property is set to null, the application uses the default engine. The default engine is DirectX if the Use DirectX option is enabled in the Project settings; otherwise, the default engine is GDI+.
