Remove 'None' option in DropdownList of Kendo UI Scheduler Popup Editor
Environment

| Product | Progress® Kendo UI® Scheduler for jQuery |
Description
How can I prevent having 'None' as an option and as a default value in the DropdownList of the Scheduler Popup Editor Form?
Solution
-
Hide the 'None' option by setting the display to none for the selector 'div.k-list-optionlabel'.
div.k-list-optionlabel { display: none; } -
Set the 'defaultValue' in the schema.model.fields.fieldName.
schema: { fields: { roomId: { from: "RoomID", defaultValue: 1 } } } -
By default, the 'nullable' parameter is set to false as seen in the Model.define method. You can also set the 'nullable' parameter to false.
schema: { fields: { roomId: { from: "RoomID", nullable: false } } }Example
<style>
div.k-list-optionlabel {
display: none;
}
</style>
<div id="example" class="k-content">
<div id="scheduler"></div>
</div>
