SelectAllChange

events

Fired when the user clicks the "Select all" header item or activates it via keyboard. The event is preventable — calling e.preventDefault() cancels the built-in select/deselect-all logic so the application can implement its own (for example, fetching and selecting all records from a remote data source).

The event handler function context (available via the this keyword) will be set to the widget instance.

selectAllChange

Event Data

e.checked `Boolean`

true when the action is selecting all items, false when deselecting.

e.preventDefault `Function`

If invoked, the default select/deselect-all behavior is canceled and the widget state is left unchanged, allowing the handler to apply its own selection logic.

e.sender `kendo.ui.MultiSelect`

The widget instance which fired the event.

    <option>Item1</option>
    <option>Item2</option>
    <option>Item3</option>
