.NET MAUI DataForm VerticalStackLayout Definition

The DataFormVerticalStackLayout definition allows you to arrange the items in a vertical stack layout.

Use the Spacing(double) property to specify the spacing in pixels between the items in the layout. Default value is 24.

Here is the DataForm XAML definition with DataFormVerticalStackLayout applied:

<telerik:RadDataForm x:Name="dataForm">
    <telerik:RadDataForm.LayoutDefinition>
        <telerik:DataFormVerticalStackLayout Spacing="30"/>
    </telerik:RadDataForm.LayoutDefinition>
    <telerik:RadDataForm.BindingContext>
        <local:EditorsViewModel/>
    </telerik:RadDataForm.BindingContext>
</telerik:RadDataForm>

Note that local in the snippet above points to the namespace where the EditorsViewModel is defined.

The ViewModel used for the DataForm editors:

public class EditorsViewModel : NotifyPropertyChangedBase
{
    private string name;
    private DateTime? startDate;
    private DateTime? endDate;
    private double? people;
    private bool? visited;
    private TimeSpan? duration;
    private EnumValue accommodation = EnumValue.Apartment;
    public enum EnumValue
    {
        SingleRoom,
        Apartment,
        House
    }

    [Required]
    [Display(Name = "Select accomodation")]
    public EnumValue Accommodation
    {
        get
        {
            return this.accommodation;
        }
        set
        {
            if (this.accommodation != value)
            {
                this.accommodation = value;
                this.OnPropertyChanged();
            }
        }
    }

    [Required]
    [Display(Name = "First Name")]
    public string FirstName
    {
        get => this.name;
        set => this.UpdateValue(ref this.name, value);
    }

    [Required]
    [Display(Name = "Start date")]
    public DateTime? StartDate
    {
        get => this.startDate;
        set => this.UpdateValue(ref this.startDate, value);
    }

    [Required]
    [Display(Name = "End Date")]
    public DateTime? EndDate
    {
        get => this.endDate;
        set => this.UpdateValue(ref this.endDate, value);
    }

    [Required]
    [Display(Name = "Number of People")]
    [Range(1, 10)]
    public double? People
    {
        get => this.people;
        set => this.UpdateValue(ref this.people, value);
    }

    [Display(Name = "Visited before")]
    public bool? Visited
    {
        get => this.visited;
        set => this.UpdateValue(ref this.visited, value);
    }

    [Display(Name = "Duration")]
    public TimeSpan? Duration
    {
        get => this.duration;
        set => this.UpdateValue(ref this.duration, value);
    }
}
