Hi,

I had a MultiSelectDropdown to select classroom of students, like "1st grade", "2nd grade".

Based on this selections, I gonna send notification for the students in the groups.

MultiSelectDropdown was a easy way that I found instead use a grid control.

Thanks.

Hi Fillipe, 

 

Good day to you. 

 

We would like to know that your requirement “” and it can be achieved by getting selected value using Multiselect instance as in the below code example, 

 

CSHTML 

@Html.EJS().MultiSelect("default").DataSource((IEnumerable<object>)ViewBag.data).Render() 

@Html.EJS().Button("Btn").Content("Send").Render() 

 

<script> 

    document.getElementById('Btn').onclick = function () { 

        var obj = document.getElementById('default').ej2_instances[0], value = JSON.stringify({ text: obj.text }); 

        const Http = new XMLHttpRequest(); 

        const url = '@Url.Action("About")'; 

        Http.open("POST", url); 

        Http.setRequestHeader('Content-Type', 'application/json'); 

        Http.send(value); 

    }; 

</script> 

   

CS 

public ActionResult Index() 

{ 

    ViewBag.data = new string[] { "Badminton", "Basketball", "Cricket", "Football", "Golf", "Gymnastics", "Hockey", "Tennis" }; 

    return View(); 

} 

 

[HttpPost] 

public ActionResult About(string text) 

{ 

    //Get the value in text      

    return View(); 

} 

 

Could you please check the above details and get back to us if you need any further details on this?

But when the preselected values are send by model, I'm using a MultiSelectFor(m=> m.DAluno), it's show the datatype of array values, like the attachement.
