DevExpress ASP.NET Gantt (ASPxGantt) allows you to edit data. The default control settings (GanttSettingsEditing) enable users to modify tasks and their dependencies and assign or re-assign resources responsible for a certain task.
Users can edit cell values within the Task List region or use the chart's context menu, dialog or another chart UI to manage tasks and their scope. The component immediately saves changes on the server and updates the chart.
The Gantt stores the changes made by users and supports the universal 'undo' and 'redo' shortcuts (Ctrl+Z and Ctrl+Y) to do one step back or forward in history.
