The MultiSelect has built-in support to select multiple values through checkbox, when mode property set as CheckBox.
To use checkbox, inject the CheckBoxSelection module in the MultiSelect.
@Html.EJS().MultiSelect("default").Placeholder("Select games").DataSource((IEnumerable<object>)ViewBag.data).Mode(Syncfusion.EJ2.DropDowns.VisualMode.CheckBox).Fields(new Syncfusion.EJ2.DropDowns.MultiSelectFieldSettings { Text = "Game", Value = "Id" }).Render()using System;
using System.Collections.Generic;
using System.Linq;
using System.Threading.Tasks;
namespace WebApplication1.Models
{
public class GameList
{
public string Id { get; set; }
public string Game { get; set; }
public List<GameList> GameLists()
{
List<GameList> game = new List<GameList>();
game.Add(new GameList { Id = "Game1", Game = "American Football" });
game.Add(new GameList { Id = "Game2", Game = "Badminton" });
game.Add(new GameList { Id = "Game3", Game = "Basketball" });
game.Add(new GameList { Id = "Game4", Game = "Cricket" });
game.Add(new GameList { Id = "Game5", Game = "Football" });
game.Add(new GameList { Id = "Game6", Game = "Golf" });
game.Add(new GameList { Id = "Game7", Game = "Hockey" });
game.Add(new GameList { Id = "Game8", Game = "Rugby" });
game.Add(new GameList { Id = "Game9", Game = "Snooker" });
game.Add(new GameList { Id = "Game10", Game = "Tennis" });
return game;
}
}
}Select All
The MultiSelect control has in-built support to select the all list items using Select All options in the header.
When the showSelectAll property is set to true, by default Select All text will show. You can customize the name attribute of the Select All option by using selectAllText.
For the unSelect All option, by default unSelect All text will show. You can customize the name attribute of the unSelect All option by using unSelectAllText.
@Html.EJS().MultiSelect("default").Placeholder("Select games").DataSource((IEnumerable<object>)ViewBag.data).Mode(Syncfusion.EJ2.DropDowns.VisualMode.CheckBox).ShowSelectAll(true).SelectAllText("Select All").UnSelectAllText("UnSelect All").Fields(new Syncfusion.EJ2.DropDowns.MultiSelectFieldSettings { Text = "Game", Value = "Id" }).Render()using System;
using System.Collections.Generic;
using System.Linq;
using System.Threading.Tasks;
namespace WebApplication1.Models
{
public class GameList
{
public string Id { get; set; }
public string Game { get; set; }
public List<GameList> GameLists()

List<GameList> game = new List<GameList>();
game.Add(new GameList { Id = "Game1", Game = "American Football" });
game.Add(new GameList { Id = "Game2", Game = "Badminton" });
