name

The name used to identify a built-in button.

Type:

String

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

JavaScript

$(function () {
    $("#treeListContainer").dxTreeList({
        // ...
        columns: [{
            type: "buttons",
            buttons: [{
                name: "save",
                cssClass: "my-class"
            }]
        }]
    });
});

React

App.js

import React from 'react';
import 'devextreme/dist/css/dx.light.css';

import TreeList, {
    Column,
    Button
} from 'devextreme-react/tree-list';

            <Column type="buttons">

                />
            </Column>
        </TreeList>
    );
}

onClick

A function that is executed when the button is clicked or tapped. Not executed if a template is used.

Type:

Function

|

String

Function parameters:

e:

Object

Information about the event that caused the function's execution.

Object structure:

Name	Type	Description
column	TreeList Column	The properties of the button's column.
component	TreeList	The UI component's instance.
element	HTMLElement \| jQuery	The UI component's container. It is an HTML Element or a jQuery Element when you use jQuery.
event	Event (jQuery or EventObject)	The event that caused the function to execute. It is a dxEvent or a jQuery.Event when you use jQuery.
model	Object	The model data. Available only if you use Knockout.
row	TreeList Row	The properties of the button's row.

render

An alias for the template property specified in React. Accepts a rendering function. Refer to Using a Rendering Function for more information.

template

Specifies a custom button template.

Type:

template

Template Data:

Name	Type	Description
column	TreeList Column	The column's properties.
columnIndex	Number	The index of the cell's column. Refer to Column and Row Indexes for more information.
component	TreeList	The UI component's instance.
data	Object	The data of the cell's row.
key	any	The row's key.
row	TreeList Row	The row's properties.
rowIndex	Number	The index of the cell's row. Begins with 0 on each page. Group rows are included. Refer to Column and Row Indexes for more information.

IMPORTANT

When you use a custom button template, the onClick function is ignored. Instead, handle the click event of the element placed inside the template:

jQuery

index.js

$(function() {
    $("#treeListContainer").dxTreeList({
        columns: [
            // ...    
            {
                type: "buttons",
                buttons: [{
                    template: function() {
                        var link = $("<a>").text("My command")
                                        .attr("href", "#");
                        link.on("click", function() {
                            console.log("My command was clicked");
                        });
                        return link;
                    }
                }]

Type:

String

visible

Specifies the button's visibility.

Type:

Boolean

|

Function

Function parameters:

options:

Object

Information about the row and column that contain the button.

Object structure:

Name

Type

Description

column

TreeList Column

The column's properties.

component

TreeList

The UI component's instance.

row

TreeList Row

The row's properties.

Return Value:

Boolean

true if the button should be visible; otherwise, false.

Default Value: true

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

JavaScript

$(function () {
    $("#treeListContainer").dxTreeList({
        // ...
        columns: [{
            type: "buttons",
            buttons: [{
                text: "Cancel",
                visible: function (e) {
                    return !e.row.isEditing && !e.row.data.isCompleted;
