Introducing the New Blazor AppBar Component

#blazor #csharp #dotnet #webdev

We are happy to introduce the new Blazor AppBar component in our Essential Studio 2022 Volume 3 release. The AppBar component is used to display information related to the current application page.

Let’s explore the Blazor AppBar component, its UI design, and its available features, with code examples.

Overview

The Blazor AppBar is also known as an action bar or nav bar. It displays information and actions related to the current app screen. We can use this component to show branding, screen titles, navigation, and actions.

Key features

The key features of the Blazor AppBar component are:

AppBar modes

The AppBar provides different types of height modes: regular, prominent, and dense.

Regular mode

The regular mode is the default mode, letting the control be viewed with its default height. Refer to the following code.

<SfAppBar ColorMode="AppBarColor.Primary">
  <SfButton CssClass="e-inherit" IconCss="e-icons e-menu"></SfButton>
  <span class="regular">Blazor AppBar</span>
  <AppBarSpacer></AppBarSpacer>
  <SfButton CssClass="e-inherit" Content="FREE TRIAL"></SfButton>
</SfAppBar>
Enter fullscreen mode Exit fullscreen mode

Prominent mode

You can view the Blazor AppBar with longer titles and images, and provide a stronger presence, by setting the Mode property to AppBarMode.Prominent.

Refer to the following code example.

<SfAppBar Mode="AppBarMode.Prominent" CssClass="prominent-appbar" ColorMode="AppBarColor.Primary">
    <SfButton aria-label="menu" CssClass="e-inherit menu" IconCss="e-icons e-menu"></SfButton>
    <span class="prominent">Blazor AppBar Component with Prominent mode</span>
    <AppBarSpacer></AppBarSpacer>
    <SfButton CssClass="e-inherit login" Content="FREE TRIAL"></SfButton>
</SfAppBar>

<style>
    .prominent {
        align-self: center;
        white-space: break-spaces;
        text-align: inherit;
        font-size: 35px;
        line-height: 50px;
    }

    .e-appbar.prominent-appbar {
        background-image: url("@UriHelper.ToAbsoluteUri($"{SampleService.WebAssetsPath}images/appbar/prominent.png")");
        background-size: 100% 400px;
        color: #ffffff;
        background-repeat: no-repeat;
        height: 400px;
    }
</style>
Enter fullscreen mode Exit fullscreen mode

Dense mode

Dense mode helps us to compress the AppBar to accommodate all its content in a denser layout. To do so, set the Mode property to AppBarMode.Dense like in the following code example.

<SfAppBar Mode="AppBarMode.Dense" ColorMode="AppBarColor.Primary">
    <SfButton CssClass="e-inherit" IconCss="e-icons e-menu"></SfButton>
    <span class="dense">Blazor AppBar</span>
    <AppBarSpacer></AppBarSpacer>
    <SfButton CssClass="e-inherit" Content="FREE TRIAL"></SfButton>
</SfAppBar>
Enter fullscreen mode Exit fullscreen mode

AppBar color modes

You can use the following color modes in the AppBar:

  • Primary
  • Light
  • Dark
  • Inherit

Primary

You can render the AppBar with the primary mode by setting the ColorMode property to AppBarColor.Primary.

<SfAppBar ColorMode=”AppBarColor.Primary”> 
    <SfButton CssClass=”e-inherit” IconCss=”e-icons e-menu”></SfButton> 
    <span class=”regular”>Blazor AppBar</span> 
    <AppBarSpacer></AppBarSpacer> 
    <SfButton CssClass=”e-inherit” Content=”FREE TRIAL”></SfButton> 
</SfAppBar>
Enter fullscreen mode Exit fullscreen mode

Light

To render the AppBar with the light mode, set the ColorMode property to AppBarColor.Light.

<SfAppBar ColorMode="AppBarColor.Light"> 
    <SfButton CssClass="e-inherit" IconCss="e-icons e-menu"></SfButton> 
    <span class="regular">Blazor AppBar</span> 
    <AppBarSpacer></AppBarSpacer>

    <span class="regular">Blazor AppBar</span> 
    <AppBarSpacer></AppBarSpacer> 
    <SfButton CssClass="e-inherit" Content="FREE TRIAL"></SfButton> 
</SfAppBar>

The AppBar can inherit its color from its parent element. To render the AppBar with its parent element’s color, set the ColorMode property to AppBarColor.Inherit.

<SfAppBar ColorMode="AppBarColor.Inherit">   
    <SfButton CssClass="e-inherit" IconCss="e-icons e-menu"></SfButton> 
    <span class="regular">Blazor AppBar</span> 
    <AppBarSpacer></AppBarSpacer> 
    <SfButton IsPrimary="true" Content="FREE TRIAL"></SfButton> 
</SfAppBar>

Blazor AppBar with inherit modeIf you render the following Syncfusion components inside the AppBar component, you can use the e-inherit class in its CssClass to inherit the AppBar’s styles:

Refer to the following code example.

<SfAppBar ColorMode="AppBarColor.Primary">
    <SfButton CssClass="e-inherit menu" IconCss="e-icons e-menu"></SfButton>
    <SfButton CssClass="e-inherit home e-appbar-menu e-primary" Content="Home"></SfButton>
    <SfDropDownButton CssClass="e-inherit e-appbar-menu e-primary" Content="Products">
        <DropDownMenuItems>

Rendering Syncfusion components in Blazor AppBar to inherit styles

AppBar position

You can place the AppBar component at the top or bottom of your app page.

Top

To place the AppBar at the top of the page, set the Position property to AppBarPosition.Top.

<SfAppBar ColorMode=”AppBarColor.Primary” Position=”AppBarPosition.Top”>
    <SfButton CssClass=”e-inherit” IconCss=”e-icons e-menu”></SfButton>
    <AppBarSpacer></AppBarSpacer>
    <SfButton CssClass=”e-inherit” Content=”FREE TRIAL”></SfButton>

Sticky AppBar

You can render the AppBar with a fixed position while scrolling the page. This will not impact the other content of the page, and some of the content will be displayed behind the AppBar. You can achieve this by enabling the IsSticky property.

Refer to the following code example.

<SfAppBar ColorMode=”AppBarColor.Primary” IsSticky=”true”>
    <SfButton CssClass=”e-inherit” IconCss=”e-icons e-menu”></SfButton>
    <AppBarSpacer></AppBarSpacer>
    <AppBarSeparator></AppBarSeparator>
    <SfButton CssClass=”e-inherit” Content=”FREE TRIAL”></SfButton>
</SfAppBar>
Enter fullscreen mode Exit fullscreen mode

Content arrangements

The Blazor AppBar supports the following two child components to arrange the AppBar content:

  • AppBarSpacer
  • AppBarSeparator

AppBarSpacer

AppBarSpacer inserts space among the AppBar contents, which gives additional space to the content layout.

Refer to the following code to use the AppBarSpacer in primary color mode.

<SfAppBar ColorMode="AppBarColor.Primary">
    <SfButton CssClass="e-inherit" IconCss="e-icons e-menu"></SfButton>
    <AppBarSpacer></AppBarSpacer>
    <SfButton CssClass="e-inherit" Content="FREE TRIAL"></SfButton>
</SfAppBar>
Enter fullscreen mode Exit fullscreen mode

Blazor AppBarSpacer

Refer to the following code example to use the AppBarSpacer in light color mode.

<SfAppBar ColorMode="AppBarColor.Light">
  <SfButton CssClass="e-inherit" IconCss="e-icons e-menu"></SfButton>
  <AppBarSpacer></AppBarSpacer>
  <span class="regular">Blazor AppBar</span>
  <AppBarSpacer></AppBarSpacer>
  <SfButton CssClass="e-inherit" Content="FREE TRIAL"></SfButton>
</SfAppBar>
Enter fullscreen mode Exit fullscreen mode

AppBarSeparator

AppBarSeparator displays a separator line to visually group or separate the AppBar contents.

Refer to the following code example. In it, we have rendered a separator between the Search box and the FREE TRIAL button.

<SfAppBar ColorMode="AppBarColor.Light">
    <SfButton CssClass="e-inherit menu" IconCss="e-icons e-menu"></SfButton>
    <SfButton CssClass="e-inherit home e-appbar-menu e-primary" Content="Home"></SfButton>    
    <AppBarSpacer></AppBarSpacer>
    <div style="width: 200px; margin-right:10px">
        <span class="e-input-group e-control-wrapper e-inherit">
            <input type="text" class="e-searchinput e-input" placeholder="Search">
            <span class="e-icons e-search e-input-group-icon"></span>
        </span>
    </div>
    <AppBarSeparator></AppBarSeparator>
    <SfButton IsPrimary="true" Content="FREE TRIAL"></SfButton>
</SfAppBar>
Enter fullscreen mode Exit fullscreen mode

The Blazor AppBar is a highly responsive UI component. It will adapt and fit any device screen size.

Refer to the following code example.

<SfAppBar ColorMode="AppBarColor.Primary">
    <SfButton CssClass="e-inherit" IconCss="e-icons e-menu"></SfButton>
    <SfButton CssClass="e-inherit" Content="Essential Studio for Blazor"></SfButton>
    <AppBarSpacer></AppBarSpacer>
    <div style="width: 400px;">
        <span class="e-input-group e-control-wrapper e-inherit">
            <input type="text" class="e-searchinput e-input" placeholder="Search">
            <span class="e-icons e-search e-input-group-icon"></span>
