Description

The change event of the DropDownList fires when the value of the widget is changed by the user. How can I detect changes in the input of the Kendo UI DropDownList?

Solution

The following example demonstrates how to achieve the desired scenario.

  <div id="example">
    <div class="demo-section k-header">
      <h4 class="title">DropDownList</h4>
      <input id="dropdownlist" style="width: 400px;"/>
    </div>
    <div class="box">                
      <h4>Console log</h4>
      <div class="console"></div>
    </div>
    <script>
      $(document).ready(function() {
        function widgetChange(е) {
          var value = this.value();
          $(".console").append("<p>event: change (widget) -- selected value: " + value + "</p>");
        };

        function inputChange() {
          var val = $("#dropdownlist").val()
          $(".console").append("<p>event: change (input)-- selected value: " + val + "</p>");
        };

        var data = [
          {text: "Item1", value:"1"},
          {text: "Item2", value:"2"},
          {text: "Item3", value:"3"}
        ];

        $("#dropdownlist").kendoDropDownList({
          dataTextField: "text",
          dataValueField: "value",
          dataSource: data,
          change: widgetChange
        });

        $("#dropdownlist").change(inputChange);
      });
    </script>            
    <style scoped>
      .demo-section {
        width: 400px;
      }
    </style>   
  </div>
