The Microsoft Backstage view, new to Microsoft Office 2010, replaces the traditional File menu. The Backstage view provides a centralized space for file management tasks such as opening new or existing files, defining document properties, and sharing information. Like the Microsoft Office Fluent ribbon, the Backstage view is fully extensible using XML to define the structure, components, and callback procedures to give those components functionality.
This article describes how to create a document-specific customized Backstage view. The Backstage view customization includes a custom Fast Command button and shows using callback procedures to dynamically set how a group of controls displays based on conditions at the time that the Backstage view is shown.
This article uses Trang Luu's Custom UI Editor to simplify adding custom user interface (UI) XML to the Microsoft Excel 2010 workbook. You must download and install the Custom UI Editor to follow the steps provided in this article.
This article describes how to customize a Microsoft Excel 2010 workbook's Backstage view using a combination of XML and VBA code. The XML defines a custom tab and the controls to display in the Backstage view. The VBA code provides the functionality that is required by the callback procedures defined in the custom UI XML.
This article contains the following steps to show creating a customized Backstage view in an Excel 2010 workbook:
Create a New Excel Workbook
In this article, you add custom UI XML and VBA code to a new Excel 2010 workbook. You must create the Excel 2010 workbook as a macro-enabled workbook (.xlsm) to support the VBA code.
To create the workbook
Add the Custom UI XML
The Custom UI Editor simplifies adding the Custom UI XML to the Excel 2010 workbook created in the previous step.
To add the custom UI XML
Add the VBA Callback Code
The VBA callback procedures add functionality to the custom Backstage view components added through the custom UI XML in the previous step.
To add the VBA callback code
View the Custom Backstage View Page
To view the custom Backstage view page and fast command button defined in the previous example, you must display the Backstage view by selecting the File tab. After you display the Backstage view, select the Dynamic Control Format tab that is located under the built-in Info tab. When you select the Dynamic Control Format tab, you can see and interact with the custom Dynamic Control Format Backstage view page.
The Save & Close fast command button is displayed in the Backstage view with the built-in fast command buttons and is located below the built-in Save As fast command button.
Extending the Office 2010Backstage view to include custom pages and fast command buttons to support your own needs is a combination of adding custom UI XML to the Office document and adding VBA code to provide the functionality for the callbacks specified in the custom UI XML.
The sample code in this article shows how to perform actions every time that the Backstage view is displayed. The sample code also shows how to create a custom fast command button for actions that you frequently perform.
Initialize the Custom UI
In some cases, a callback procedure makes a change that requires redisplaying Backstage view controls. To redisplay the Backstage view controls, call the RibbonUI control's Invalidate method.
The following code example shows how to store a reference to the RibbonUI control when the custom UI is loaded. The customUI element contains the onLoad attribute which, in this instance, specifies the callback OnLoad. The OnLoad callback stores a reference to the RibbonUI object which is used in callbacks to redisplay the Backstage view controls.
Perform Actions When Backstage View is Displayed
There may be instances where you want to do something when the Backstage view is displayed. For example, changing the format of controls, depending on the last time that the workbook is saved. TheWork Status group in this example calls attention to itself when the workbook is not saved recently by displaying a red or yellow highlight. The value depends on how long it is since the workbook was saved. Backstage view groups set their display style by using the getStyle callback which returns one of the BackstageGroupStyle enumeration values:
The following custom UI XML example shows how to specify callbacks to dynamically define how controls are displayed on the page based on conditions when the Backstage view is displayed. The backstage element specifies an onShow callback that evaluates how long it is since the workbook was saved and sets the style for the Work Status group. The onShow callback executes every time that the Backstage view is displayed. The Work Status group specifies the getStyle and getHelperText callbacks which return the appropriate style and text that is based on the style set by the onShow callback.
The following code example shows how the backstage element onShow callback, OnShow, emphasizes the Work Status group based on the last time that the workbook was saved. The OnShow callback calculates how many seconds it is since the workbook was saved and sets the workStatusGroupStyle variable to the appropriate BackStageGroupStyle enumeration value. When the workStatusGroupStyle variable is set, the Invalidate method for the RibbonUI object redisplays the Backstage view controls. When the Invalidate method is called, the Works Status group's getStyle and getHelperText callbacks are re-executed.
The following code example shows how the Work Status group getStyle callback, the GetWorkStatusStyle callback, the getHelperText callback, and the GetWorkStatusHelperText callback are used to emphasize the group based on the last time that the workbook was saved. The GetWorkStatusStyle callback returns the BackstageGroupStyle value of the workStatusGroupStyle variable that is set by the OnShow callback when the Backstage view is displayed. The GetWorkStatusHelperText works in parallel with the GetWorkStatusStyle callback by returning text appropriate for the BackstageGroupStyle value.
Creating a Fast Command Button
Fast commands are useful for options that you frequently use. This article describes creating a fast command button that saves the current workbook and closes the Backstage view, returning to the workbook.
The following custom UI XML example shows how to define a fast command button. The button element for a fast command button is defined as a child of the backstage element. The label contains an ampersand (&), which is added by using two && concatenated tokens. The insertAfterMSO attribute is set to FileSaveAs to display the Save & Close button under the built in Save As fast command button. The OnAction callback saves the workbook when you click the Save & Close button. The isDefinitive attribute is set to True to close the Backstage view and return to the workbook when you click the Save & Close button.
The following code example shows how the Save & Close fast command button's onAction callback, SaveAndClose, saves the current workbook and closes the Backstage view. The SaveAndClose callback only saves the current workbook. Closing the Backstage view and returning to the current workbook occurs by setting the control's isDefinitive attribute in the custom UI XML.
