Connect to the Kendo dropdown list undefined

I am looking to automatically bind a model to a Kendo dropdown list. The model is retrieved from the server and can sometimes be undefined or a valid object.

My problem arises when the value is undefined. In this case, Kendo selects the first item in the dropdown list by default. I would prefer it to display the dropdown with no selection made.

For more details, you can visit this link

 <select kendo-drop-down-list
                name="eventType"
                k-ng-model="itemSelected"
                k-options="eventTypeDropDown">
 </select>

$scope.itemSelected = undefined;

If anyone has a solution for this issue, please let me know.

Thank you! Zohar

Answer №1

One way to solve this issue is by utilizing the optionLabel property in your code:

$scope.dropDownOptions= {
  optionLabel:' ',
    dataTextField: "name",
    dataValueField: "id",
    autoBind: true,
    dataSource: {
        ...
        }
    }

If your model is undefined, using optionLabel with a space will display the drop down list without any pre-selected item. It appears that leaving optionLabel completely empty does not work as expected, you must include at least a space character.
