EXTJS Problem with date field please help

i'm having trouble trying to figure out how this is happening. i'm using Extjs and AJAX with JsonStore from my callback my page in ASP call the database and return some fields in this fields there is a Date and this date return the proper date ex.: "date_creat_post": "29\u002F04\u002F2011"...

Now once i look at my output from this in my page in a datagrid i'm getting the following:

04/05/2013 <----> the date it return in the callback is 04/05/2011

06/05/2012 <----> the date it return in the callback is 06/05/2010

07/04/2012 <----> the date it return in the callback is 07/04/2010

I looked all threw my code to see if they're is a place where i am adding 1 year to the date. but can't find it. i have been trying now for at least 2 days to figure this out.

Here's my code:

    Ext.onReady(function(){

Ext.QuickTips.init();

// for this demo configure local and remote urls for demo purposes
var url = {
    local:  '',  // static data file

var encode = true;

// configure whether filtering is performed locally or remotely (initially)
var local = false;

Thanks in advance i hope some on on the wicked web can help me....

cheers.

so after trying many solution giving to be i came to this has problem finally the the date example after many attemps to format and inserting in my msSQL database this problem is the problem : 13\09\2011 (d/m/Y) becomes this 09/01/2012 (d/m/Y) so for some reason the month 13 is being added to the month so say the 13 month doesn't exist so the date will go to 09/01/2012....

after looking again it's the format that doesn't seem ok so i changed it de (m/d/Y) and now im getting a sql error when i hit 13 day on my datefield in (extjs).

"The conversion of a varchar data type to a datetime data type resulted in an out-of-range value."

and on and on does anyone have any ideas now ????

Instead of using the built in Ext.util.Format.dateRenderer, you could try creating one of your own that parses the Date as desired.

ataIndex: 'date_creat_post',
    header: 'Date Created',
   renderer:  daterenderer

And then a function for your daterenderer:

function dateRenderer(value, id, r) {
 var myDate = r.data['date_creat_post'];
 // do some things here to strip out the date and make it into a happy format
 var d = new Date(myDate);
 return d.format('d/m/Y');
}
