Чтобы установить значение столбца B на основе изменений, внесенных в столбец A, необходимо отредактировать модель, связанную с древовидным списком.Для этого сделайте следующее: -
- Обработка события редактирования списка дерева.При этом сохраните модель в локальной переменной.
- Добавьте шаблон редактора в столбец A. При событии выбора установите значение модели.
Нижефрагмент рабочего кода: -
<div id="treelist"></div>
