name
To configure a built-in button, assign its name to this property. The other properties in the object configure the button. For example, the following code adds a custom CSS class to the Save button:
jQuery
$(function () { $("#ganttContainer").dxGantt({ // ... columns: [{ type: "buttons", buttons: [{ name: "save", cssClass: "my-class" }] }] }); });
Angular
<dx-gantt ... > <dxi-column type="buttons"> <dxi-button name="save" cssClass="my-class"> </dxi-button> </dxi-column> </dx-gantt>
import { DxGanttModule } from "devextreme-angular"; // ... export class AppComponent { // ... } @NgModule({ imports: [ // ... DxGanttModule ], // ... })
Vue
<template> <DxGantt ... > <DxColumn type="buttons"> <DxButton name="save" css-class="my-class" /> </DxColumn> </DxGantt> </template> <script> import 'devextreme/dist/css/dx.light.css'; import DxGantt, { DxColumn, DxButton } from 'devextreme-vue/gantt'; export default { components: { DxGantt, DxColumn, DxButton }, // ... } </script>
React
import React from 'react'; import 'devextreme/dist/css/dx.light.css'; import Gantt, { Column, Button } from 'devextreme-react/gantt'; export default function App() { return ( <Gantt ... > <Column type="buttons"> <Button name="save" cssClass="my-class" /> </Column> </Gantt> ); }

Use the function to show or hide the button for specific rows. For example, the UI component lists online orders and allows users to edit them. The Cancel button should allow users to cancel their orders. However, completed orders should not be canceled. The visible function in this case may look as follows:
jQuery
$(function () { $("#ganttContainer").dxGantt({ // ... columns: [{ type: "buttons", buttons: [{ text: "Cancel", visible: function (e) { return !e.row.isEditing && !e.row.data.isCompleted; } }] }] }); });
Angular
<dx-gantt ... > <dxi-column type="buttons"> <dxi-button text="Cancel" [visible]="isCancelButtonVisible"> </dxi-button> </dxi-column> </dx-gantt>
import { DxGanttModule } from "devextreme-angular"; // ... export class AppComponent { isCancelButtonVisible (e) { return !e.row.isEditing && !e.row.data.isCompleted; } } @NgModule({ imports: [ // ... DxGanttModule ], // ... })
Vue
<template> <DxGantt ... > <DxColumn type="buttons"> <DxButton text="Cancel" :visible="isCancelButtonVisible" /> </DxColumn> </DxGantt> </template> <script> import 'devextreme/dist/css/dx.light.css'; import DxGantt, { DxColumn, DxButton } from 'devextreme-vue/gantt'; export default { components: { DxGantt, DxColumn, DxButton }, // ... methods: { isCancelButtonVisible (e) { return !e.row.isEditing && !e.row.data.isCompleted; } } } </script>
React
import React from 'react'; import 'devextreme/dist/css/dx.light.css'; import Gantt, { Column, Button } from 'devextreme-react/gantt'; function isCancelButtonVisible (e) { return !e.row.isEditing && !e.row.data.isCompleted; } export default function App() { return ( <Gantt ... > <Column type="buttons"> <Button text="Cancel" visible={isCancelButtonVisible} /> </Column> </Gantt> ); }
