well this a pagingtoolbar:

var paging = new Ext.PagingToolbar({
pageSize: PageSize,
store: callsStore,
displayInfo: true,
displayMsg: '{0} - {1} of {2}',
emptyMsg: ''

this is my grid

callsGrid = new Ext.grid.GridPanel({
id: 'callsGrid',
// el: 'callsGrid',
height: 400,
width: 820,
frame: true,
border: true,
title: 'Bulletins',
store: callsStore,
colModel: colModel,
bbar: paging

here is the store load

callsStore.load({params: {start:'0',limit:'10}});

and well if and put next and later I put back, the paging is normal from "1-10 of 16"(displaying info) and in the text is "Page 1 of 2", and If I put again next appears "Page 2 of 2", so my problem is when for first time create the grid the paging is wrong, only when load the grid for first time

Be certain (a) that you do specify the page-size, and (b) that your initial "Load" request specifies a chunk of records corresponding to one page.

Subsequently, pay attention to "reload()" vs. "load()" so that you do not lose the start/limit settings and accidentally wind up requesting the world. I put them in "baseParams."

Be sure that you do tests with large datasets just to be sure that nothing like this has slipped through.

What does your store config look like?

I agree with mike, you might want to specify your pageSize (very important).

I am not sure if autoDestroy needs to be set to true.

Your Server Response might be causing the problem.
you need to return and specify them in the Reader a total count, root, and idProperty.

I didn't do this, and my display went wonky.

Did you try making start/limit numbers instead of strings?
