jQuery Grid Plugin - jqGrid

Hello,

I have 20 jqGrids on page. These grids are set to datatype: 'local' to prevent data loading on initialization ( I fire data loading on user request).

The problem is, that the initialization of all grids takes about 3s - I measured time in gridComplete function.

What I need is to show the page to user before this initialization or fasten grid initialization.

Can You please suggest me any solution to this? I'm lost...

Grid code example:

jQuery(document).ready(function() {

jQuery("#EmailsGrid").jqGrid({
sortable:true,
 jsonReader: {
                userdata: 'UserData'
            },
 xmlReader: {
                userdata: 'UserData'
            },
url: '/CRM/Email/EmailList',
datatype: 'local',
mtype: 'POST',
postData: {filter : '_fn-CRMEmail_Account_FK_cmpop-EqualTo_val-'+21286+'%7cAND%7c'},
colNames: ['ID','PÅ™edmÄ›t','Od','Pro','VytvoÅ™en','PÅ™iÅ™azen k','Typ','Status','Privátní',''],
colModel: [
