Answer 1

try putting the config option
remoteFilter : true
to your store from which you are loading the data to the list.ie
new Ext.data.Store({
model: 'Test',
sortOnLoad: true,
remoteFilter : true,
autoLoad: true,
getGroupString : function(record) {
return record.get('FullName_FirstLast')[0];
},
proxy: {
type: 'ajax',
url : testUrl,
reader: {
type: 'json',
root: 'test'
}
}
})
