Build the Team Efficiency Dashboard Project

Step 9: Make the Application Responsive

In this chapter you'll learn how to make the dashboard application look amazing on any device size. The Team Efficiency Dashboard layout uses Bootstrap for some basic responsive functionality. However, more detailed controls, such as the Grid, need extra attention to ensure a proper user experience on any device size. In the next few steps you'll take the app from desktop, to anywhere, with a few key changes.

Responsive Grid

Overview

Run the project and shrink the browser window horizontally to about 400 pixels wide. Refresh the browser and observe how the application elements stack nicely, but the grid bleeds off the page. There is simply too much information in the grid to show at this screen size. By setting a few properties we can remove non-essential columns from the grid for small screens.

Exercise: Make the Grid Mobile Friendly with Responsive APIs

1. Open Views/Invoice/Index.cshtml and find where the Columns are defined in the EmployeeSales grid.

   Razor

    .Columns(columns =>
    {
        ...
    })

   Remove the Salesperson column completely. The sales person is already displayed at the top of the page.

2. Set the MinScreenWidth of the CustomerName column to 900. This means that the column will no longer be displayed on screen sizes less than 900 pixels wide.

3. Set the MinScreenWidth of the ProductName column to 768. This means that the column will no longer be displayed on screen sizes less than 768 pixels wide.

   Razor

    .Columns(columns =>
    {
        columns.Bound(c => c.CustomerName).MinScreenWidth(900);
        columns.Bound(c => c.OrderDate).Format("{0:MM/dd/yyyy}");
        columns.Bound(c => c.ProductName).MinScreenWidth(768);
        columns.Bound(c => c.UnitPrice);
        columns.Bound(c => c.Quantity);
    })

4. Refresh the page, then shrink and grow the browser to different widths to see how the grid reacts at various sizes.

   

Responsive Panel

Overview

When changing the screen size, you may have noticed the Report Range side bar disappear. If not, take a moment to adjust the browser width again to see the side bar's behavior. Currently, the sidebar is hidden using the Bootstrap's hidden-xs class. Bring back the side bar using a Kendo UI ResponsivePanel and make a seamless user experience on any device size.

Exercise: Add a Responsive Panel Side Bar

1. Open Views/Home/Index.cshtml and find the <!-- Menu Panel --> placeholder. Below the <!-- Menu Panel --> placeholder add a ResponsivePanel. Set the Name to menuPanel and set the Breakpoint to 768.

2. Add a Content property and include all of the elements until you reach the ending <!-- /Menu Panel --> placeholder.

   The at symbol @ is used as an escape charter for HTML content.

   The resulting code should be like the one shown in the example below.

   Razor

    <!-- Menu Panel -->
        @(Html.Kendo().ResponsivePanel().Name("menuPanel").Breakpoint(768).Content(
        @<div class="hidden-xs" style="float:left;">
            ...
        </div>
    ))
    <!-- /Menu Panel -->

3. Remove class="hidden-xs" style="float:left;" from the div element in the newly added responsive panel.

   Razor

    <!-- Menu Panel -->
        @(Html.Kendo().ResponsivePanel().Name("menuPanel").Breakpoint(768).Content(
        @<div>
            ...
        </div>
    ))
    <!-- /Menu Panel -->

4. Next, add a button for users to tap and toggle the responsive panel.

5. Find the block of code shown in the example below.

   Razor

    <section id="app-title-bar" class="row">
        <div class="col-sm-3">
            <h1 class="title">@ViewBag.Title</h1>
        </div>
    </section>

   After the section's closing tag </section>, add a new div with a class of hamburger.

6. Inside the hamburger div, create a Kendo UI Button. Set the following button's properties:

   • Name: menuPanelOpen
   • Content: menu
   • Icon: more-horizontal
   • HtmlAttributes: new { @class = "k-rpanel-toggle" }

   Any element with the k-rpanel-toggle class will be able to toggle the current page's responsive panel.

   Razor

    <div class="hamburger">
        <!-- toggle button for responsive panel, hidden on large screens -->
        @(Html.Kendo().Button()
                    .Name("menuPanelOpen")
                    .Content("menu")
                    .Icon("more-horizontal")
                    .HtmlAttributes(new { @class = "k-rpanel-toggle" })
        )
    </div>

7. Open Content/Site.css and find the /* Top Bar */ placeholder.

   Razor

    /* Top Bar */

1. Add a style that selects the hamburger element and sets the position to absolute. Give the style a top of 5 and left of 5 to create a margin around the element.

   Razor

    .hamburger {
        position: absolute;
        top: 5px;
        left: 5px;
    }

2. Add a style that selects the menuPanel. Set a solid background color of #fff (white), include a padding of 10px and z-index of 3. This style will ensure that the panel appears above other UI elements and has a solid background.

   Razor

    #menuPanel {
        background-color: #fff;
        padding: 10px;
        z-index: 3;
    }

3. Run or refresh the application. Expand and contract the browser's width, notice the Menu button appear when the browser is small. Click the Menu button to open the panel. Click beside the panel to collapse it.

4. For a better user experience, add a Close button to the panel so the interaction is discoverable and intuitive.

5. Find the menuPanel and add a Kendo UI Button inside the Content's first div. Set the following button's properties:

   • Name: menuPanelClose
   • Content: Close
   • Icon: close
   • HtmlAttributes: new { @class = "k-rpanel-toggle" }

6. Wrap the button in a div with a class of text-right to position the button on the right hand edge of the panel.

   Razor

    @(Html.Kendo().ResponsivePanel().Name("menuPanel").Breakpoint(768).Content(
    @<div>
        <div class="text-right">
            @(Html.Kendo().Button()
               .Name("menuPanelClose")
               .Content("Close")
               .Icon("x")
               .HtmlAttributes(new { @class = "k-rpanel-toggle" })
            )
        </div>
        ...
     </div>

7. Refresh the application. Expand and contract the browser's width until the Menu button is shown. Toggle the responsive panel using the Menu and Close buttons.

   

The application is almost complete, just apply a nice bright theme and it will be ready to ship.
