The All-New .NET MAUI Tab View Control Is Here

The .NET Multi-platform App UI (MAUI) is an evolution of Xamarin.Forms. It mainly focuses on single project development for different platforms such as Android, iOS, macOS, and Windows.

Syncfusion has shipped a set of cool .NET MAUI tools that includes Charts, Radial Gauge, and Tab View controls in the 2021 Volume 3 release. These controls are really fast, feature-rich, and flexible to use in your .NET MAUI applications.

In this blog, we will introduce the .NET MAUI Tabbed View control along with code examples.

.NET MAUI Tabbed View (Preview)

The advanced .NET  MAUI Tabbed View is a simple and intuitive interface for tab navigation. You can use it in both mobile and desktop applications, wherever you want your users to explore and switch between different tabs.

Tab View overview

  • Optimizes screen space usage when an application requires complex and huge layouts.
  • Contains a set of tab items that present different content in the same space.
  • Shows only one tab item at a time to be accessed by the user. The user taps another tab to make its content visible on the screen.

Tab width mode

The .NET MAUI Tabbed View provides two width options: default and size to content.  These options determine how to calculate the width of the tabs on the tab bar when it is populated.

Default

In the default option, the width of all the tabs is equally divided based on the width of the tab bar. This enables a fixed tab bar that does not allow tab scrolling regardless of the number of tabs.

Size to content

You can use this option when you need to set the width of a tab so that it fits the text or image that it contains. This option enables tab scrolling when the arrangement of the tabs and their width exceeds the tab bar’s width.

The .NET MAUI Tabbed View provides four options that determine how an image in a tab aligns relative to the tab’s text. The available options are top, bottom, left, and right.

Top

The top option places the image above the text.

Selection indicator placement

The .NET MAUI Tabbed View provides three options that determine how the selection indicator aligns relative to the tab header item content. The available options are top, bottom, and fill.

Top

The selection indicator is places at the top of the selected tab.

Nested tabs

This support allows users to have a nested tab view. You can also configure a tab view within another tab view through its Items property.

<syncfusion:SfTabView>
<syncfusion:SfTabItem Header="Item 1">
<syncfusion:SfTabView>
<syncfusion:SfTabItem Header="Item 1 SubItem 1"/>
<syncfusion:SfTabItem Header="Item 1 SubItem 2"/>
</syncfusion:SfTabView>
</syncfusion:SfTabItem>
<syncfusion:SfTabItem Header="Item 2">
<syncfusion:SfTabView>
<syncfusion:SfTabItem Header="Item 2 SubItem 1"/>
<syncfusion:SfTabItem Header="Item 2 SubItem 2"/>
</syncfusion:SfTabView>
</syncfusion:SfTabItem>
</syncfusion:SfTabView>

Ripple animation

The built-in ripple animation matches the Material theme. This animation also provides a better taping experience to the user.

Color and font customization

You can easily customize all fonts and theirs colors with simple APIs.

Visual state manager

Use the visual state manager to make changes to the .NET MAUI Tabbed View item properties based on the visual states set in the code. The applicable visual states are selected, normal, enable and disable.

<Style TargetType="TabView:SfTabItem">
<Setter Property="VisualStateManager.VisualStateGroups">
<VisualStateGroupList>
<VisualStateGroup>
<VisualState x:Name="Selected" >
<VisualState.Setters>
<Setter Property="TextColor" Value="Red" />
<Setter Property="ImagePosition" Value="Top" />
<Setter Property="FontSize" Value="16" />
<Setter Property="FontAttributes" Value="Bold" />
</VisualState.Setters>
</VisualState>
<VisualState x:Name="Normal">
<VisualState.Setters>
<Setter Property="TextColor" Value="Black" />
<Setter Property="ImagePosition" Value="Left" />
<Setter Property="FontSize" Value="12" />
<Setter Property="FontAttributes" Value="Italic" />
</VisualState.Setters>
</VisualState>
</VisualStateGroup>

Looks beautiful. I would also need badges on a tab in my application. It would be very useful if you can implement it here.
