Description

How can I set the Switch in an indeterminate state?

Solution

The Switch behaves as a checkbox element. Its indeterminate state is used only for visual representation and, in this way, the Switch remains either in its checked or unchecked state.

The following example demonstrates how to set the Switch in an indeterminate state.

  <style>
      .k-indeterminate .k-switch-container {
          background-color: #dfdfdf !important;
      }
  </style>

  <input type="checkbox" id="switch" />

  <script>
    var switchButton = $("#switch").kendoSwitch({
        checked: true,
        messages: {
            checked: "Yes",
            unchecked: "No",
        },
        change: function (e) {
            if (!e.checked) {
                if (!e.sender.element.prop("indeterminate")) {
                    e.sender.element.prop("indeterminate", true);
                    e.sender.wrapper.addClass("k-indeterminate");

                    e.sender.setOptions({messages: {checked: "N/A"}});
                    e.preventDefault();
                } else {
                    e.sender.element.prop("indeterminate", false);
                    e.sender.wrapper.removeClass("k-indeterminate");

                    e.sender.setOptions({messages: {checked: "Yes"}});
                }
            }
        }
    }).data("kendoSwitch");

  </script>
