Description

How can I make a read-only text visible in the input field of a Kendo UI ComboBox widget?

Solution

The following example demonstrates how to achieve the desired scenario.

To see how the example works:

  1. Select Chai from the Drag: Chai field.

  2. Drag it to the input field of the ComboBox.

  3. Release the mouse.

  <div id="example">
    <div class="demo-section k-header">
      <h4>Products</h4>
      <div> Drag: Chai </div>
      <input id="products" style="width: 400px" />
    </div>
    <script>
      $(document).ready(function() {
        $("#products").kendoComboBox({
          placeholder: "Select product",
          dataTextField: "ProductName",
          dataValueField: "ProductID",
          filter: "contains",
          autoBind: false,
          minLength: 3,
          dataSource: {
            type: "odata",
            serverFiltering: true,
            transport: {
              read: {
                url: "https://demos.telerik.com/kendo-ui/service/Northwind.svc/Products",
              }
            }
          }
        });

        //Wire the drop event
        var combobox = $("#products").data("kendoComboBox");

        combobox.input.on("drop", function(e) {
          var input = e.currentTarget;
          var droppedText = e.originalEvent.dataTransfer.getData("text");

          setTimeout(function() {
            input.value = droppedText;
            combobox.search(droppedText);
          });
        });
      });
    </script>

    <style scoped>
      .demo-section {
        width: 400px;
      }
    </style>
  </div>
