Hi,

Please advise what's wrong with this approach. It was perfectly valid in v1.x but returns null now. I'm trying to get a handle on the GridPanel object from a checkbox residing in its PagingToolbar:



<%@ Page Language="C#" %>

<%@ Import Namespace="System.Xml" %>

<%@ Register Assembly="Ext.Net" Namespace="Ext.Net" TagPrefix="ext" %>

<script runat="server">
private object[] TestData
{
get

DateTime now = DateTime.Now;

Hi Vadym,

Now there is the powerful ComponentQuery feature.
http://docs.sencha.com/extjs/4.2.0/#!/api/Ext.ComponentQuery

Please use:

var grid = this.up('gridpanel');
