How to add a custom button in magento2 admin grid

How to add a custom button in magento2 admin grid-

In the Create Grid , Edit/Add Grid Row And Installer In Magento2 blog we created an simple Grid module.

Now we are going to add a custom button “Send Mail” to custom grid in Magento2.

On click of the ” Send Mail ” button we will just show a form in popup which will be responsible to send an custom email to customer.

For this we will need to follow some simple steps given below –

1. Add customer_listing.xml file to your module in path –
2. app/code/Webkul/Grid/view/adminhtml/ui_component/customer_listing.xml and add a custom button in this file

<?xml version="1.0" encoding="UTF-8"?>
<listing xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:module:Magento_Ui:etc/ui_configuration.xsd">
    <columns name="customer_columns">
        <actionsColumn name="send_mail" class="Webkul\Grid\Ui\Component\Listing\Columns\Sendmail">
            <argument name="data" xsi:type="array">
                <item name="config" xsi:type="array">
                    <item name="component" xsi:type="string">Webkul_Grid/js/grid/columns/sendmail</item>
                    <item name="indexField" xsi:type="string">entity_id</item>
                    <item name="sortable" xsi:type="boolean">false</item>
                    <item name="label" xsi:type="string" translate="true">Send Mail</item>
                    <item name="sortOrder" xsi:type="number">13</item>
                </item>
            </argument>
        </actionsColumn>
    </columns>
</listing>

3. As we want to show an form on click on this custom “Send Mail” button , now we need to create a ui component class Webkul\Grid\Ui\Component\Listing\Columns\Sendmail –

<?php

namespace Webkul\Grid\Ui\Component\Listing\Columns;

use Magento\Framework\UrlInterface;
use Magento\Framework\View\Element\UiComponent\ContextInterface;
use Magento\Framework\View\Element\UiComponentFactory;
use Magento\Ui\Component\Listing\Columns\Column;

class Sendmail extends Column
{
    /**
     *@var UrlInterface
     */
    protected $urlBuilder;
    /**
     * Constructor
     *
     * @param ContextInterface $context
     * @param UiComponentFactory $uiComponentFactory
     * @param UrlInterface $urlBuilder
     * @param array $components
     * @param array $data      
     */
    public function __construct(
        ContextInterface $context,
        UiComponentFactory $uiComponentFactory,
        UrlInterface $urlBuilder,
        array $components = [],
        array $data = []
    ) {
        $this->urlBuilder = $urlBuilder;
        parent::__construct($context, $uiComponentFactory, $components, $data);
    }
    /**      
     * Prepare Data Source
     * 
     * @param array $dataSource
     * @return array
     */
    public function prepareDataSource(array $dataSource)
    {
        if (isset($dataSource['data']['items'])) {
            $fieldName = $this->getData('name');
            foreach ($dataSource['data']['items'] as &$item) {
                $item[$fieldName . '_html'] = "<button class='button'><span>Send Mail</span></button>";
                $item[$fieldName . '_title'] = __('Please enter a message that you want to send to customer');
                $item[$fieldName . '_submitlabel'] = __('Send');
                $item[$fieldName . '_cancellabel'] = __('Reset');
                $item[$fieldName . '_customerid'] = $item['entity_id'];
                $item[$fieldName . '_formaction'] = $this->urlBuilder->getUrl('grid/customer/sendmail');
            }
        }
        return $dataSource;
    }
}

4. Now we will need to create a js file sendmail.js at below
path.

app/code/Webkul/Grid/view/base/web/js/grid/columns/ which we are using in this custom button.

define(
    ['Magento_Ui/js/grid/columns/column',
        'jquery', 'mage/template',
        'text!Webkul_Grid/templates/grid/cells/customer/sendmail.html',
        'Magento_Ui/js/modal/modal'], function (Column, $, mageTemplate, sendmailPreviewTemplate) {
            'use strict'; return Column.extend({
                defaults: {
                    bodyTmpl: 'ui/grid/cells/html',
                    fieldClass: { 'data-grid-html-cell': true }
                },
                gethtml: function (row) {
                    return row[this.index + '_html'];
                },
                getFormaction: function (row) {
                    return row[this.index + '_formaction'];
                },
                getCustomerid: function (row) {
                    return row[this.index + '_customerid'];
                },
                getLabel: function (row) { return row[this.index + '_html'] },
                getTitle: function (row) { return row[this.index + '_title'] },
                getSubmitlabel: function (row) { return row[this.index + '_submitlabel'] },
                getCancellabel: function (row) { return row[this.index + '_cancellabel'] },
                preview: function (row) {
                    var modalHtml = mageTemplate(sendmailPreviewTemplate, {
                        html: this.gethtml(row),
                        title: this.getTitle(row),
                        label: this.getLabel(row),
                        formaction: this.getFormaction(row),
                        customerid: this.getCustomerid(row),
                        submitlabel: this.getSubmitlabel(row),
                        cancellabel: this.getCancellabel(row),
                        linkText: $.mage.__('Go to Details Page')
                    });
                    var previewPopup = $('<div/>').html(modalHtml);
                    previewPopup.modal({
                        title: this.getTitle(row),
                        innerScroll: true, modalClass: '_image-box',
                        buttons: []
                    }).trigger('openModal');
                },
                getFieldHandler: function (row) { return this.preview.bind(this, row); }
            });
        });

5. Now we have to create a template file sendmail.html in path app/code/Webkul/Grid/view/base/web/templates/grid/cells/customer/ .

<form id="send-mail-form-<%- customerid %>" method="get" enctype="multipart/form-data" action="<%- formaction %>">
    <div class="modal-body">
        <div class="bootbox-body"> <textarea class="bootbox-input bootbox-input-text form-control required-entry"
                name="send_message" rows="4" cols="83"></textarea> <input type="hidden" name="entity_id"
                value="<%- customerid %>"> </div>
    </div>
    <div class="modal-footer"> <span class="error"></span> <button type="reset" class="btn btn-default"><span><%-
                    cancellabel %></span></button> <button type="submit" class="btn btn-primary"><span><%- submitlabel
                    %></span></button> <span class="clear"></span> </div>
</form>

now you will see a custom button “Send Mail” is added in the magento2 customer grid as shown in the given screenshot-on click on “Send Mail” button you will see a form in popup which will be responsible to send a custom mail to customer.So in this way you can add any custom button or any custom column like action link, image to any grid in magento2.
