Is it possible to change the enabled / disabled status of a dropdownlist through a button?

[Juan Cruz]

Hello, I am working with a dropdownlist with the property enabled in false and I wanted to know if it can be changed to true through a button

Here is my code:

@(Html.EJS().DropDownList("GenreId")

                                                    .DataSource(dataManager => dataManager.Url(Url.Action("Genre", "Ext", null, Request.Url.Scheme))

                                                        .Adaptor("UrlAdaptor").CrossDomain(true))

                                                    .Fields(new Syncfusion.EJ2.DropDowns.DropDownListFieldSettings

                                                    {

                                                        Text = "Name",

                                                        Value = "GenreId"

                                                    })

                                                    .PopupHeight("200px")

                                                    .Width("200px")

                                                    .Value(Model.GenreId).Enabled(false)

                                                    .Render()

                                        )

<button class="btn btn-success" id="btnChange">Change</button>

<script type="text/javascript">

     $("#btnChange").click(function(){

          var x = document.getElementById("GenreId").ej2_instances[0];

          x.element.disabled = false;

        x.element.readOnly = false;

        x.properties.enabled = true;

});

</script>

I do not know if this is the right way to do it. I hope you can help me.

Thanks in advance

Hello Juan, 

Thank you for contacting Syncfusion support. 

Yes, it is possible to change the enabled / disabled status of a DropDownList through a button. All you need to do is use the enabled property in the control and set it as true to enable and false to disable it. You can call the dataBind method to reflect the changes immediately in the control. Please refer the below code. 

$("#btnChange").click(function () { 

  var x = document.getElementById("GenreId").ej2_instances[0]; 

  if (x.enabled) { 

    x.enabled = false; // To disable 

    x.dataBind(); //To affect the changes immediately 

  } else { 

    x.enabled = true; // To enable 

    x.dataBind(); //To affect the changes immediately 

  } 

}); 

Let us know if you have any further queries. 

Thanks, 

Prince
