Checkbox does not check when clicked

[Alexandre]

The title says it all. When I click on the checkbox, there is no change of state of checkbox to Checked

My model:

    public class TituloPendente
    {
        public int TituloID { get; set; }
        public bool Selecionado { get; set; }
        public string NumeroDoDocumento { get; set; }
        public string NossoNumero { get; set; }
        public DateTime DataDeVencimento { get; set; }
        public decimal Valor { get; set; }
    }

My Home Controller:

    public class HomeController : Controller
    {
        private static readonly object objLock = new object();

        public ActionResult Index()
        {
            List<SyncfusionMvcApplication1.Models.TituloPendente> titulos = new List<Models.TituloPendente>();

            for (int i = 0; i < 100; i++)
            {
                Random rnd = new Random((int)Math.Cos((double)(i + 1)));

                lock (objLock)
                {
                    titulos.Add(new Models.TituloPendente()
                    {
                        TituloID = 1,
                        NumeroDoDocumento = (i + 1 * 8454548).ToString(),
                        NossoNumero = (i + 1 * 6544456).ToString(),
                        DataDeVencimento = DateTime.Now.AddDays(i),
                        Valor = (decimal)((15.02m * (i + 1)) + (decimal)((double)((i + 1) % 45646) / Math.Sqrt((double)(rnd.Next(1, 45645646))))),
                        Selecionado = false
                    });
                }
            }

            return View(titulos);
        }
    }

My View:

Hi Alexandre,

Thanks for contacting Syncfusion Forums.

QUERY: CheckBox doesn't check when clicked

From the code you have shared, we can undestand that you are using "displayAsCheckbox" property for showing the column as check box column. When you use "displayAsCheckbox" property, you can check/uncheck it in edit mode(by double clicking the cell). 

Please let us know the below details, so that we can help you to achieve it,

1) Whether you need to check/ uncheck in single click

2) Please explain us your requirement with clarity(what you are trying to do with the check box)

3) Version Details

4) Screenshot of error with stacktrace(if any)

If you have further queries, please get back to us.

Hi Alexandre,

Thanks for your update.

QUERY: Need to select some rows and send to controller 

From your query we understand that you need to select rows using checkbox and send the selectes rows to the controller. This can be done by following below steps,

1) Render checkbox as column using type property. Please check below help documentation,

https://help.syncfusion.com/aspnetmvc/grid/columns#type

2) Select checkboxes and in actionComplete event with requestType as "paging", you can get the selected records's primary key value and save it to array when you navigate from one page to other.

Please check below help documentations,

https://help.syncfusion.com/api/js/ejgrid#members:selectedrecords

https://help.syncfusion.com/api/js/ejgrid#events:actioncomplete

3) In button click event, using AJAX, you can send the selected Record's primary key value to controller. In Controller, you can compare the passed primary key value with your data model and perform your functionalities.

Please check below code,

@Html.EJ().Button("mute").Size(ButtonSize.Large).ShowRoundedCorner(true).ClientSideEvents(e => e.Click("click")).Text("Mute")

@(Html.EJ().Grid<object>("FlatGrid")

                .Datasource((IEnumerable<object>)ViewBag.datasource)

                                .AllowPaging()

                                .ClientSideEvents(eve => { eve.ActionComplete("actionComplete"); })

                                .Columns(col =>

                                {

                                    col.Field("OrderID").HeaderText("Order ID").IsPrimaryKey(true).TextAlign(TextAlign.Right).Width(75).Add();

                                    col.Type("checkbox").HeaderText("check").Width(90).Add();

                                })

)

<script>

    var primaryKeyValuesArray = []; 

    function click(args) {

        var selectedData = primaryKeyValuesArray; // array of primary key values

        $.ajax({

              // pass to controller

        });

    }

    function actionComplete(args) {

        if (args.requestType == "paging") { 

            var data1 = this.model.selectedRecords, len1 = data1.length, arrayLength = primaryKeyValuesArray.length;

            for (i = 0; i < len1; i++) {

                var value = data1[i]["OrderID"]; // orderID is primarykey column field

                primaryKeyValuesArray.push(value);

                console.log(primaryKeyValuesArray);

            }

        }  

    }

</script>
