Returns

Type
Byte

Remarks

Call this function to obtain the starting alpha blending value of the control’s background color. This value is specified by the control’s background style. The style is set via the OptionsStyle.DefaultStyles.Background default style. These settings, in turn, can be overridden by assigning a custom style to the OptionsStyle.CustomStyles.Background property of the NavBar control. The BgAlphaBlend function returns the AlphaBlending property value of the style assigned.

The BgAlphaBlend function can be used when handling the OnCustomDraw.Background event. It is useful if you don’t want to use custom alpha components of colors.
