How to change the Cell background based on bool value in .NET MAUI DataGrid?

The .NET MAUI DataGrid provides support to customize the background of a DataGridCell based on a bool value.

XAML
Create a custom style targeting the DataGridCell in the Resource Dictionary.

<ContentPage.Resources>
    <local:ColorConverter x:Key="converter"/>
    <Style TargetType="syncfusion:DataGridCell" x:Key="customCellStyle">
        <Setter Property="Background" Value="{Binding EmployeeStatus, Converter={StaticResource Key=converter}}"/>
    </Style>
</ContentPage.Resources>

Set the key value to the CellStyle property of the column you want to customize.

<syncfusion:SfDataGrid ItemsSource="{Binding Employees}" CellTapped="SfDataGrid_CellTapped">
    <syncfusion:SfDataGrid.Columns>
        <syncfusion:DataGridNumericColumn MappingName="EmployeeID" 
                                          HeaderText="Employee ID" 
                                          Format="d"
                                          ColumnWidthMode="Auto"
                                          CellStyle="{StaticResource customCellStyle}"/>        
    </syncfusion:SfDataGrid.Columns>
</syncfusion:SfDataGrid>

C#

In the cell tapped event, we will modify the bool value, which will trigger the converter.

private void SfDataGrid_CellTapped(object sender, DataGridCellTappedEventArgs e)
{
    if (e.RowData != null && viewModel.Employees.Contains(e!.RowData))
    {
        int index = viewModel.Employees.IndexOf((e.RowData as Employee)!);
        viewModel.Employees[index].EmployeeStatus = !viewModel.Employees[index].EmployeeStatus;
    }
}

In the converter we set the background based on the bool value.

public class ColorConverter : IValueConverter
{
    object IValueConverter.Convert(object? value, Type targetType, object? parameter, CultureInfo info)
    {
        if ((bool)value!)
            return Color.FromArgb("bde0fe"); 
        else
            return Colors.Transparent;
    }
    public object ConvertBack(object? value, Type targetType, object? parameter, CultureInfo culture)
    {
        throw new NotImplementedException();
    }
}
