Reading Pane
Touch UI provides the built-in option to display the details of the selected record side-by-side with the master list.

Reading Pane

Popular email applications have proven this presentation style to be very effective. The end user can view the details of the selected message and has the quick access to the contents of the inbox.

The prototype of this presentation style has been a part of the framework for the past two years. Our team was able to bring it to the production state just now. The technical challenge was to provide a simultaneous access to the master and detail panes each holding a virtual page of the Touch UI application. A consistent styling has also been worked out.



The reading pane detail is empty by default. The placeholder area is filled with the standard background image that can be changed in ~/touch-settings.json through the ui.readingPane.background parameter. Set the option to false to disable the image or specify your own alternative (for example, ~/images/app-bkg.jpg).



The modal form fills this area when a selection is made in the master list or a new item is created. Both master and detail panes can be scrolled and are fully interactive. The familiar form buttons are migrated to the top of the detail pane and have icons to complement the toolbar of the master pane.



Set the option ui.actions.form.icons to true to enable action icons in all forms of the app. By default, only the form buttons in the reading pane are rendered with icons.

If the reading pane is not enabled then the familiar modal presentation will take place when the user is interacting with the master list.


Any forms activated from the detail pane are displayed on the top of the reading pane.


The option to enable the reading pane is available to the end user through the view selector if the screen size is that of a typical tablet. Developers can also tag the data view on the page as reading-pane-auto to activate the reading pane by default. The option and the mode are not activated if the screen is small.


Touch UI allows specifying the default minimal size of the reading pane master and detail in ~/touch-settings.json through the options ui.readingPane.minLeft, ui.readingPane.minRight, ui.readingPane.minTop, and ui.readingPane.minBottom. The default value for these options is 375 measured in pixels.

The device with the vertical orientation will display the reading pane detail at the bottom of the screen.



The master pane displays all supported presentation styles.


Hover over or touch the middle divider and drag it to the desired position to change the panes.


The responsive Touch UI will present the data in the best way possible within the available space of master and detail panes.


The reading pane mode enhances the productivity of the end users and requires zero effort on the part of the developer. If for any reason this mode is not desirable, then disable it with ui.readingPane.enabled option in ~/touch-settings.json. The reading pane mode is available only on the pages with a single master dataview.

Removing Header Text from Views
The responsive user interface of apps created with Code On Time is intuitive.  Nevertheless the grids and forms do display generic text to provide basic user instructions.

This is an example of a grid view with the header text displayed above the data.


This is how the data form may look.


Each description can be changed individually in the Project Designer.

If you prefer a minimalist user interface then the descriptions may appear to be excessive. The unique architecture of apps created with Code On Time makes possible altering various aspects of an app with a just few lines of code.

For example, enable shared business rules in your app by selecting the corresponding option in Settings | Database Model & Business Logic | Shared Business Rules section of the project configuration. Re-generate the app. If you have existing custom "code" business rules, then open each rule and change the base class from BusinessRules to SharedBusinessRules.

Application framework will create an instance of SharedBusinessRules class or a custom version of it whenever a client request is processed through the server-side code. The framework retrieves the XML description of the corresponding data controller to handle the request.Then it provides the app with a chance to perform changes to the in-memory copy of the data controller. If the matching business rules class indicates that it supports data controller virtualization (customization at runtime), then the customization code is invoked. By default, no customization is performed. Developer can override virtualization code to make changes to the controller.

The header text definitions in views of data controllers are as shown in this sample:



Changed the file ~/app/App_Code/custom/Rules/SharedBusinessRules.cs as follows:

namespace MyCompany.Rules
{
    public partial class SharedBusinessRules : MyCompany.Data.BusinessRules
    {

        public override bool SupportsVirtualization(string controllerName)
        {
            return true;
        }

        protected override void VirtualizeController(string controllerName)
        {
            NodeSet().SelectViews().SetHeaderText(string.Empty);
        }
    }
}

Save the code file and observe that all views in the app are displayed without descriptions:



You can customize your data controllers selectively by inspecting the name of the data controller specified in the argument of VirtualizeController method.

Take you minimalist presentation even further by removing category descriptions in form views with this code.

protected override void VirtualizeController(string controllerName)
{
    NodeSet().SelectViews().SetHeaderText(string.Empty)
        .SelectCategory("c1").SetHeaderText(string.Empty).SetDescription(string.Empty);
}

Your forms will now have an even more streamlined data-only presentation:

Home Page and Toolbar

Let’s explore a few customization ideas for the home page and toolbar of your app.

The default home page displays a table of contents. The toolbar has “hamburger” button (“bars” icon) of the left side and content menu button (“more” icon) on the right sidebar. The illustration is presented in Light theme with Modern accent.

The default home page of app based on Touch UI features a table of contents.

A customized home of an app based on Touch UI may display marketing and informative content to the end users instead of a default table of contents. Let’s remove the table of contents from the home page and replace it with a marketing message for the end users of the app.

Have you noticed that the new design does not have the Menu and More buttons on the toolbar?

By default the data pages of the app do display both buttons just like the default home page with the table contents.

The standard features of the toolbar in apps based on Touch UI are Menu and Context buttons.

Let’s hide the Menu and More buttons on the toolbar on the data pages as well.

This is how the data pages will look when the left sidebar is expanded.

Select the project name on the start page of the app generator and locate “Home” page in the Project Explorer on the right hand side of the Project Designer.

Right-click and delete both containers on the page.  This will remove the table of contents displayed to the authenticated users and the welcome message displayed to anonymous users.

Double-click the home page, select Jumbotron as the Template, save changes, and generate the app. Inspect the home page. It will look similar to the one in the picture. Try other templates to find the best fit for your app.

Sample customization of the home page in an app based on Touch UI.

Lock the page from being overwritten during the code generation before making any changes to the content of the template. Double-click the home page in the Project Explorer and specify First Time Only in the Generate property. Save the changes. The home page icon will display with the “lock” indicating that any changes to the app will be preserved if the page exists already.

Click Develop on the toolbar of the Project Designer and add a new stylesheet with the name of choosing under ~/app/css/ folder.

Custom stylesheet in an app based on Touch UI created with Code On Time app generator.

Enter the following CSS rules in the file app/css/StyleSheet.css.

/* 1. Hide "hamburger" button when the toolbar does not have the "Back' button  */

.app-bar-toolbar:not(.app-has-back) #app-btn-menu {
    visibility: hidden;
}

/* 2. Hide the context button with "more" icon*/

.app-bar-toolbar #app-btn-context {
    visibility: hidden;
}

/* 3. Align the logo area of the page with the content when there is no sidebar on the left side */

body:not(.app-has-sidebar-left) .app-bar-toolbar .app-logo {
    left: 16px;
}

/* 4. Shift the logo text more to the left in the expanded sidebar */

body.app-has-sidebar-left:not(.app-has-minisidebar-left) .app-bar-toolbar .app-logo {
    left: 20px;
}

/* 5. Move the "icon" buttons of the toolbar to the right */

.app-bar-toolbar .app-btn-cluster-right .app-btn {
    margin-right: -28px;
}

The comments provided next to the CSS rules explain their effect on the User Interface of the app.

Rules (1) and (2) are hiding Menu and More buttons on the toolbar. Rule (3) shifts the text in the Logo area to the left when the sidebar is not visible.

The same rules also apply to data pages. A data page of an app based on Touch UI with customized toolbar on a narrow screen is shown next.

If the screen of the device is narrow then modal pages will be automatically replaced with fullscreen pages. In that case rule (1) does not apply and the Back is visible next to the name of the previous view.
