.x-grid-cell-inner { overflow: hidden;
padding: 3px 6px; white-space: normal;}

Is this what you had in mind?


Ext.create('Ext.data.Store', {
fields:['name', 'email', 'change'],
{ 'name': 'Lisa', "email":"lisa@simpsons.com", "change":100 },
{ 'name': 'Bart', "email":"bart@simpsons.com", "change":-20 },
{ 'name': 'Homer', "email":"Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat. Duis aute irure dolor in reprehenderit in voluptate velit esse cillum dolore eu fugiat nulla pariatur. Excepteur sint occaecat cupidatat non proident, sunt in culpa qui officia deserunt mollit anim id est laborum", "change":23 },
{ 'name': 'Marge', "email":"marge@simpsons.com", "change":-11 }
proxy: {
type: 'memory',
reader: {
type: 'json',
root: 'items'

var largeeditor = {
xtype: 'textarea',
grow: true,
allowBlank: false

var cellEditing = Ext.create('Ext.grid.plugin.CellEditing', {
clicksToEdit: 1

Ext.create('Ext.grid.Panel', {
title: 'Simpsons',
store: Ext.data.StoreManager.lookup('simpsonsStore'),
columns: [
{ header: 'Name', dataIndex: 'name', editor: { xtype: 'textfield' } },
{ header: 'Email', dataIndex: 'email', flex: 1, tdCls: 'wrapText', editor: largeeditor },
{ header: 'Change', dataIndex: 'change', editor: { xtype: 'textfield' } }
height: 500,
width: 400,
viewConfig: {
getRowClass: function(record, index) {
var c = record.get('change');
if (c < 0) {
return 'price-fall';
} else if (c > 0) {
return 'price-rise';
renderTo: Ext.getBody(),

plugins: [ cellEditing ]

Hi Scott,
Thanks for your reply .
The given code increases only the textarea height,i need the entire row height also to be increases when the textarea height is increases dynamically.i need to do this for Row editing Grid not for the cell edit grid.

There is not a configuration available by default for this .. you will need to create an override for

Ext.define('Ext.grid.RowEditor', { .. });

ex: (created override.js)

Ext.override(Ext.grid.RowEditor, {

functionToOverride: function() {
// change code of function to override

You will have to determine which functions need to be touched. You can copy all of the functions over to the override that you feel need attention and remove untouched after.

This will allow you to make changes and not muck up the original code.

My working solution to move the floatingButtons with "Ext.grid.plugin.RowEditing" (with ExtJS 4.2.1) :

reposition : function() {

var myRowEditing = Ext.create('Ext.grid.plugin.RowEditing', {
listeners : {
'myRepositionEvent' : function() {
// Your algorithm here instead of mine...
this.editor.floatingButtons.el.setY(this.editor.el.getY() + this.editor.el.getHeight() - 1);

Ext.create('Ext.grid.Panel', {
plugins : [myRowEditing]

But I override the private class "Ext.grid.RowEditor" and I haven't took this advice :

This is a private utility class for internal use by the framework. Don't rely on its existence.
