Try this:


Ext.create('Ext.grid.Panel', {
...
selType: 'checkboxmodel',
selModel: {
renderer: function(){
var baseCSSPrefix = Ext.baseCSSPrefix;
metaData.tdCls = baseCSSPrefix + 'grid-cell-special ' + baseCSSPrefix + 'grid-cell-row-checker';
return record.get('relation') == 'parent' ? '' : '<div class="' + baseCSSPrefix + 'grid-row-checker">&#160;</div>';
}
},
...
});

Try this:

...
selType: 'checkboxmodel',
selModel: {
renderer: function(){
var baseCSSPrefix = Ext.baseCSSPrefix;
metaData.tdCls = baseCSSPrefix + 'grid-cell-special ' + baseCSSPrefix + 'grid-cell-row-checker';
return record.get('relation') == 'parent' ? '' : '<div class="' + baseCSSPrefix + 'grid-row-checker"> </div>';

Here is my full example. It works well with Ext 4.1.1 and Chrome 20. In this example, you will see, rows with price greater than 50 will not show checkbox:


Ext.onReady(function() {
Ext.define('Company', {
extend: 'Ext.data.Model',
fields: [
{name: 'company'},
{name: 'price', type: 'float', convert: null, defaultValue: undefined},
{name: 'change', type: 'float', convert: null, defaultValue: undefined},
{name: 'pctChange', type: 'float', convert: null, defaultValue: undefined},
{name: 'lastChange', type: 'date', dateFormat: 'n/j h:ia', defaultValue: undefined}
],
idProperty: 'company'
});

// sample static data for the store
var myData = [
['3m Co', 71.72, 0.02, 0.03, '9/1 12:00am'],

Hi,

The solution from vietits (http://www.sencha.com/forum/member.php?362966-vietits) worked for me.

Thanks a lot.
