The Gantt component provides the toolbar support to handle Gantt actions. The toolbar property accepts the collection of built-in toolbar items and ItemModel objects for custom toolbar items.
Built-in toolbar items execute standard actions of the Gantt component, and these items can be added to toolbar by defining the toolbar as a collection of built-in items. It renders the button with icon and text.
The following table shows built-in toolbar items and its actions.
| Built-in Toolbar Items | Actions |
|---|---|
| Add | Adds a new record. |
| Cancel | Cancels the edit state. |
| CollapseAll | Collapses all the rows. |
| Delete | Deletes the selected record. |
| Edit | Edits the selected record. |
| Indent | Indent the selected record to one level. |
| Outdent | Outdent the elected record to one level. |
| ExpandAll | Expands all the rows. |
| NextTimeSpan | Navigate the Gantt timeline to next time span. |
| PrevTimeSpan | Navigate the Gantt timeline to previous time span. |
| Search | Searches the records by the given key. |
| Update | Updates the edited record. |

- The
toolbarhas options to define both built-in and custom toolbar items.
Custom toolbar items can be added to the toolbar by defining the toolbar property as a collection of ItemModels.
Actions for this customized toolbar items are defined in the toolbarClick event.
You can check this video to learn about how to use custom toolbar in Gantt.
By default, the custom toolbar items are at left position. You can change the position by using the align property. In the following sample, the Quick Filter toolbar item is positioned at right.

- The
toolbarhas options to define both built-in and custom toolbar items.- If a toolbar item does not match the built-in items, it will be treated as a custom toolbar item.
The Gantt component has an option to use both built-in and custom toolbar items at the same time.
In the following example, the ExpandAll and CollapseAll are built-in toolbar items and Test is the custom toolbar item.
