Form Elements

Introduction

Abp provides form input tag helpers to make building forms easier.

Demo

See the form elements demo page to see it in action.

abp-input

abp-input tag creates a Bootstrap form input for a given c# property. It uses Asp.Net Core Input Tag Helper in background, so every data annotation attribute of input tag helper of Asp.Net Core is also valid for abp-input.

Usage:

<abp-input asp-for="@Model.MyModel.Name"/>
<abp-input asp-for="@Model.MyModel.Description"/>
<abp-input asp-for="@Model.MyModel.Password"/>
<abp-input asp-for="@Model.MyModel.IsActive"/>

Model:

    public class FormElementsModel : PageModel
    {
        public SampleModel MyModel { get; set; }

        public void OnGet()
        {
            MyModel = new SampleModel();
        }

        public class SampleModel
        {
            [Required]
            [Placeholder("Enter your name...")]
            [InputInfoText("What is your name?")]
            public string Name { get; set; }
            
            [Required]
            [FormControlSize(AbpFormControlSize.Large)]
            public string SurName { get; set; }

            [TextArea(Rows = 4)]
            public string Description { get; set; }
            
            [Required]
            [DataType(DataType.Password)]
            public string Password { get; set; }

            public bool IsActive { get; set; }
        }
    }

Attributes

You can set some of the attributes on your c# property, or directly on HTML tag. If you are going to use this property in a abp-dynamic-form, then you can only set these properties via property attributes.

Property Attributes

[TextArea()]: Converts the input into a text area.

[Placeholder()]: Sets the description are of the input. You can use a localization key directly.
[InputInfoText()]: Sets text for the input. You can directly use a localization key.
[FormControlSize()]: Sets the size of the form-control wrapper element. Available values are
- AbpFormControlSize.Default
- AbpFormControlSize.Small
- AbpFormControlSize.Medium
- AbpFormControlSize.Large
[DisabledInput] : Sets the input as disabled.
[ReadOnlyInput]: Sets the input as read-only.

Tag Attributes

info: Sets text for the input. You can directly use a localization key.
auto-focus: It lets the browser set focus to the element when its value is true.
size: Sets the size of the form-control wrapper element. Available values are
- AbpFormControlSize.Default
- AbpFormControlSize.Small
- AbpFormControlSize.Medium
- AbpFormControlSize.Large
disabled: Sets the input as disabled.
readonly: Sets the input as read-only.
label: Sets the label of input.
required-symbol: Adds the required symbol (*) to the label when the input is required. The default value is True.
floating-label: Sets the label as floating label. The default value is False.

asp-format, name and value attributes of Asp.Net Core Input Tag Helper are also valid for abp-input tag helper.

Label & Localization

You can set the label of the input in several ways:

You can use the Label attribute to set the label directly. This property does not automatically localize the text. To localize the label, use label="@L["{LocalizationKey}"].Value".
You can set it using [Display(name="{LocalizationKey}")] attribute of ASP.NET Core.
You can just let abp find the localization key for the property. It will try to find "DisplayName:{PropertyName}" or "{PropertyName}" localization keys, if label or [DisplayName] attributes are not set.

abp-select

abp-select tag creates a Bootstrap form select for a given c# property. It uses ASP.NET Core Select Tag Helper in background, so every data annotation attribute of select tag helper of ASP.NET Core is also valid for abp-select.

abp-select tag needs a list of Microsoft.AspNetCore.Mvc.Rendering.SelectListItem to work. It can be provided by asp-items attriube on the tag or [SelectItems()] attribute on c# property. (if you are using abp-dynamic-form, c# attribute is the only way.)

abp-select supports multiple selection.

abp-select auto-creates a select list for Enum properties. No extra data is needed. If property is nullable, an empty key and value is added to top of the auto-generated list.

Usage:

<abp-select asp-for="@Model.MyModel.City" asp-items="@Model.CityList"/>

<abp-select asp-for="@Model.MyModel.AnotherCity"/>

<abp-select asp-for="@Model.MyModel.MultipleCities" asp-items="@Model.CityList"/>

<abp-select asp-for="@Model.MyModel.MyCarType"/>

<abp-select asp-for="@Model.MyModel.MyNullableCarType"/>

Model:

 public class FormElementsModel : PageModel
    {
        public SampleModel MyModel { get; set; }
                    
        public List<SelectListItem> CityList { get; set; }

        public void OnGet()
        {
            MyModel = new SampleModel();
            
            CityList = new List<SelectListItem>
            {
                new SelectListItem { Value = "NY", Text = "New York"},
                new SelectListItem { Value = "LDN", Text = "London"},
                new SelectListItem { Value = "IST", Text = "Istanbul"},
                new SelectListItem { Value = "MOS", Text = "Moscow"}
            };
        }

        public class SampleModel
        {
            public string City { get; set; }
            
            [SelectItems(nameof(CityList))]
            public string AnotherCity { get; set; }

            public List<string> MultipleCities { get; set; }
            
            public CarType MyCarType { get; set; }

            public CarType? MyNullableCarType { get; set; }
        }
        
        public enum CarType
        {
            Sedan,
            Hatchback,
            StationWagon,
            Coupe
        }
    }

Attributes

Property Attributes

[SelectItems()]: Sets the select data. Parameter should be the name of the data list. (see example above)

[InputInfoText()]: Sets text for the input. You can directly use a localization key.
[FormControlSize()]: Sets the size of the form-control wrapper element. Available values are
- AbpFormControlSize.Default
- AbpFormControlSize.Small
- AbpFormControlSize.Medium
- AbpFormControlSize.Large

Tag Attributes

asp-items: Sets the select data. This Should be a list of SelectListItem.
info: Sets text for the input. You can directly use a localization key.
size: Sets the size of the form-control wrapper element. Available values are
- AbpFormControlSize.Default
- AbpFormControlSize.Small
- AbpFormControlSize.Medium
- AbpFormControlSize.Large
label: Sets the label of input.
required-symbol: Adds the required symbol (*) to the label when the input is required. The default value is True.

Label & Localization

You can set the label of the input in several ways:

You can use Label attribute and directly set the label. But it doesn't auto localize your localization key. So use it as label="@L["{LocalizationKey}"].Value".
You can set it using [Display(name="{LocalizationKey}")] attribute of ASP.NET Core.
You can just let abp find the localization key for the property. It will try to find "DisplayName:{PropertyName}" or "{PropertyName}" localization keys.

Localizations of combobox values are set by abp-select for Enum property. It searches for "{EnumTypeName}.{EnumPropertyName}" or "{EnumPropertyName}" localization keys. For instance, in the example above, it will use "CarType.StationWagon" or "StationWagon" keys for localization when it localizes combobox values.

abp-radio

abp-radio tag creates a Bootstrap form radio group for a given c# property. Usage is very similar to abp-select tag.

Usage:

<abp-radio asp-for="@Model.MyModel.CityRadio" asp-items="@Model.CityList" inline="true"/>

<abp-radio asp-for="@Model.MyModel.CityRadio2"/>

Model:

 public class FormElementsModel : PageModel
    {
        public SampleModel MyModel { get; set; }

        public List<SelectListItem> CityList { get; set; } = new List<SelectListItem>
        {
            new SelectListItem { Value = "NY", Text = "New York"},
            new SelectListItem { Value = "LDN", Text = "London"},
            new SelectListItem { Value = "IST", Text = "Istanbul"},
            new SelectListItem { Value = "MOS", Text = "Moscow"}
        };
        
        public void OnGet()
        {
            MyModel = new SampleModel();
            MyModel.CityRadio = "IST";
            MyModel.CityRadio2 = "MOS";
        }

        public class SampleModel
        {
            public string CityRadio { get; set; }
            
            [SelectItems(nameof(CityList))]
            public string CityRadio2 { get; set; }
        }
    }

Attributes

Property Attributes

[SelectItems()]: Sets the select data. Parameter should be the name of the data list. (see example above)

Tag Attributes

asp-items: Sets the select data. This Should be a list of SelectListItem.
Inline: If true, radio buttons will be in single line, next to each other. If false, they will be under each other.

abp-date-picker & abp-date-range-picker

abp-date-picker and abp-date-range-picker tags creates a Bootstrap form date picker for a given c# property. abp-date-picker is for single date selection, abp-date-range-picker is for date range selection. It uses datepicker jQuery plugin.

Usage:

<abp-date-picker asp-for="@Model.MyModel.MyDate" />
<abp-date-range-picker asp-for-start="@Model.MyModel.MyDateRangeStart" asp-for-end="@Model.MyModel.MyDateRangeEnd" />
<abp-dynamic-form abp-model="DynamicFormExample"></abp-dynamic-form>

Model:

 public class FormElementsModel : PageModel
    {
        public SampleModel MyModel { get; set; }

        public DynamicForm DynamicFormExample { get; set; }

        public void OnGet()
        {
            MyModel = new SampleModel();

            DynamicFormExample = new DynamicForm();
        }

        public class SampleModel
        {
            public DateTime MyDate { get; set; }
            
            public DateTime MyDateRangeStart { get; set; }
            
            public DateTime MyDateRangeEnd { get; set; }
        }

        public class DynamicForm
        {
            [DateRangePicker("MyPicker",true)]
            public DateTime StartDate { get; set; }
            
            [DateRangePicker("MyPicker",false)]
            [DatePickerOptions(nameof(DatePickerOptions))]
            public DateTime EndDate { get; set; }
            
            public DateTime DateTime { get; set; }

            public DynamicForm()
            {
                StartDate = DateTime.Now;
                EndDate = DateTime.Now;
                DateTime = DateTime.Now;
            }
        }
    
        public AbpDatePickerOptions DatePickerOptions { get; set; }
