The SHEET control organizes TABS in the Extended UI using one of the following **Tab Styles**:

**//Default//**

**//B&W//**

**//Colored//**

**//Boxed//**

When you use the "Default" style, the SHEET/TAB control uses the OS lok and feel and inherits its colors from the Operating System Theme settings.  You can override this and utilize your own colors on SHEET/TAB controls by setting the checkbox "**SHEET controls do not use the OS Theme color**" as shown in the image below.  This template setting causes the **PROP:NoTheme** property to be assigned against all SHEET controls in your application.
