This article guides you on how to center align tabs in .NET MAUI TabView for Windows and Mac platforms. To customize the placement of tabs to the center of the Windows and Mac screens, set TabWidthMode to SizeToContent and adjust TabHeaderPadding dynamically based on the screen’s width. Below is a code snippet demonstrating this approach. XAML Code <tabView:SfTabView TabWidthMode="SizeToContent"> … <\tabView:SfTabView> C# public partial class MainPage : ContentPage { public MainPage() { InitializeComponent(); } protected override void OnAppearing() { base.OnAppearing(); #if WINDOWS var window = GetParentWindow().Handler.PlatformView as MauiWinUIWindow; if (window != null) { UpdateTabHeaderPadding(window.Bounds.Width); } #elif MACCATALYST var macWindow = GetParentWindow().Handler.PlatformView as UIWindow; if (macWindow != null) { UpdateTabHeaderPadding(macWindow.Bounds.Width); } #endif } #if WINDOWS || MACCATALYST protected override void OnSizeAllocated(double width, double height) { base.OnSizeAllocated(width, height); UpdateTabHeaderPadding(width); } private void UpdateTabHeaderPadding(double width) { double totalTabWidth = 0; foreach (var tabItem in tabView.Items) { if (tabItem is Syncfusion.Maui.TabView.SfTabItem tabItemView) { totalTabWidth += tabItemView.Measure(double.PositiveInfinity, double.PositiveInfinity).Request.Width; } } double remainingSpace = ((width - totalTabWidth)); double padding = (remainingSpace / 2) ; tabView.TabHeaderPadding = new Thickness(padding, 0, 0, 0); } #endif } The TabWidthMode is set to SizeToContent so that each tab’s width is adjusted based on its content. The method UpdateTabHeaderPadding calculates the total width of all the tab items and dynamically adjusts the left padding of the tab headers to center them based on the screen width.

When the DataGrid is wrapped in a Column widget, the bottom padding creates a space between the DataGrid and the horizontal scrollbar. This can cause the scrollbar to overlap the DataGrid rows, making it difficult for the user to interact with the data. The following image demonstrates the issue. In this article, learn how to remove the horizontal scrollbar padding in the Flutter DataGrid when loading the DataGrid as a child of the Column widget. The framework-suggested solution in this query involves utilizing the MediaQuery widget to remove the bottom padding and prevent the overlap between the DataGrid and the horizontal scrollbar. Initialize the SfDataGrid widget with all the required properties. Add the DataGrid as a child of the Column widget and wrap the Column widget in a MediaQuery widget. Set the 'removeBottom' property to 'true' in the MediaQuery.removePadding method and assign it to the MediaQuery.data property. late EmployeeDataSource _employeeDataSource; List<Employee> _employees = <Employee>[]; @override void initState() { super.initState(); _employees = getEmployeeData(); _employeeDataSource = EmployeeDataSource(employees: _employees); } @override Widget build(BuildContext context) { return Scaffold( appBar: AppBar(title: const Text('Syncfusion Flutter DataGrid')), body: MediaQuery( data: MediaQuery.of(context).removePadding(removeBottom: true), child: Column( children: [ Expanded( child: SfDataGrid( source: _employeeDataSource, columns: columns, ), ), ], ), ), ); } Download the example from GitHub.
In the Flutter Event Calendar, you can add padding at the right end of a cell to interact when the calendar cells have appointments using cellEndPadding STEP 1: Inside the state initialize the default values. String? _subjectText = '', _startTimeText = '', _endTimeText = '', _dateText = '', _timeDetails = ''; STEP 2: Assign the value to cellEndPadding property of the calendar and using the onTap callback of the calendar, you can show the tapped details whether its calendar cell or appointment. child: SfCalendar( view: CalendarView.day, dataSource: getCalendarDataSource(), onTap: calendarTapped, cellEndPadding: 40, ), void calendarTapped(CalendarTapDetails details) { if (details.targetElement == CalendarElement.appointment || details.targetElement == CalendarElement.agenda) { final Appointment appointmentDetails = details.appointments![0]; _subjectText = appointmentDetails.subject; _dateText = DateFormat('MMMM dd, yyyy') .format(appointmentDetails.startTime) .toString(); _startTimeText = DateFormat('hh:mm a').format(appointmentDetails.startTime).toString(); _endTimeText = DateFormat('hh:mm a').format(appointmentDetails.endTime).toString(); _timeDetails = '$_startTimeText - $_endTimeText'; } else if (details.targetElement == CalendarElement.calendarCell) { _subjectText = "You have tapped cell"; _dateText = DateFormat('MMMM dd, yyyy').format(details.date!).toString(); _timeDetails = ''; } showDialog( context: context, builder: (BuildContext context) { return AlertDialog( title: Container(child: new Text('$_subjectText')), content: Container( height: 80, child: Column( children: <Widget>[ Row( children: <Widget>[ Text( '$_dateText', style: TextStyle( fontWeight: FontWeight.w400, fontSize: 20, ), ), ], ), Container( height: 40, child: Row( children: <Widget>[ Text(_timeDetails!, style: TextStyle( fontWeight: FontWeight.w400, fontSize: 15)), ], ), ), ], ), ), actions: <Widget>[ new FlatButton( onPressed: () { Navigator.of(context).pop(); }, child: new Text('Close')) ], ); }); } View sample in GitHub
You can format the different levels of the group by binding the converter for the loaded elements to the GroupHeaderTemplate in Xamarin.Forms SfListView. Xaml Defined group header template with converter. <syncfusion:SfListView.GroupHeaderTemplate> <DataTemplate> <ViewCell> <ViewCell.View> <StackLayout BackgroundColor="{Binding Level, Converter={StaticResource groupHeaderConverter}}" Padding="{Binding Level,Converter={StaticResource groupHeaderConverter}}"> <Label x:Name="label" Text="{Binding Key}" FontSize="22" FontAttributes="Bold" VerticalOptions="Center" HorizontalOptions="Start" /> </StackLayout> </ViewCell.View> </ViewCell> </DataTemplate> </syncfusion:SfListView.GroupHeaderTemplate> C# Set BackgroundColor and Padding to the different group levels. public class GroupHeaderConverter : IValueConverter { public object Convert(object value, Type targetType, object parameter, CultureInfo culture) { if (targetType.Name == "Color") { if ((int)value == 1) return Color.Aqua; else return Color.AntiqueWhite; } else { if ((int)value == 1) return new Thickness(5, 5, 5, 0); else return new Thickness((int)value * 15, 5, 5, 0); } } public object ConvertBack(object value, Type targetType, object parameter, CultureInfo culture) { return value; } } Output: View sample in GitHub
By default, padding is applied to all the sides of chart to avoid the cropping of axis labels and leaving some space between nearby views and chart. However, it can be removed or changed using the ChartPadding property of Xamarin.Forms Chart. In the following code snippets shows how to customize the chart padding. xaml: <chart:SfChart x:Name="chart" ChartPadding ="5,5,5,5"> ... </chart:SfChart> C#: ... SfChart chart = new SfChart() { ChartPadding = new Thickness(5) }; ...

Line padding during hit testing The Diagram control have built-in option to extend the padding size of the connector for selecting/hitting the connector by using Connector’s “LineHitTestPadding” property while hovering the mouse pointer. The following code example is used to extend the padding size of the connector. [C#] LineConnector line = new LineConnector(new Point(100, 100), new PointF(300, 300)); //the Padding added to lines during hit testing line.LineHitTestPadding = 50; [VB] Dim line As New LineConnector(New Point(100, 100), New PointF(300, 300)) 'the Padding added to lines during hit testing line.LineHitTestPadding = 50
