How can i find out what was selected in a list box in asp mvc

[Andrew Simpson]

is there any documentation on this i cant seem to find anything.
here is the code of my view so far

@model List<BusinessLayer.Employee>

    @Html.EJ().ListBox("list1").Datasource(Model).ClientSideEvents(e => { e.SelectIndexChanged("selected"); })
 
    <p id="demo">JavaScript can change HTML content.</p>
    <script type="text/javascript">
        function selected(args)
        {
            document.getElementById('demo').innerHTML = "selecteditemtext"
        }
    </script>

eventually i want to filter a grid based on the item selected or return the selected item to the controller.

thanks

Hi Andrew,

Thank you for contacting Syncfusion support.

Yes, we can pass the selected item in ListBox to controller page using Ajax post from the client side script. Define the script using AJAX post under the ListBox’s “Selected” client side event. In the controller post action we can get the data passed through the AJAX post. Please refer the code snippet below,
<code>
[CSHTML]
@Html.EJ().ListBox("list1").TargetID("carsList").ClientSideEvents(e=>e.SelectIndexChanged("onSelected"))
[Script]

<script type="text/javascript">

function onSelected(args) {

litem = args.data.selectedText; // selected item text

$.ajax({

type: "POST",

url: "ListBoxFeatures",

content: "application/json; charset=utf-8",

dataType: "json",

data: { selectedtext: litem },

complete: function (d) {

$("#mydata").text(litem);

}

});

}
</script>
[Controller]

//Post action to get the data passed from AJAX post

[HttpPost]

public ActionResult ListBoxFeatures(string selectedtext)

{

string Listboxitem = selectedtext;

return View();
}
</code>
