var myview = $.extend({},$.fn.datagrid.defaults.view,{
onAfterRender:function(target){
$.fn.datagrid.defaults.view.onAfterRender.call(this,target);
var opts = $(target).datagrid(‘options‘);
var vc = $(target).datagrid(‘getPanel‘).children(‘div.datagrid-view‘);
vc.children(‘div.datagrid-empty‘).remove();
if (!$(target).datagrid(‘getRows‘).length){
var d = $(‘<div class="datagrid-empty"></div>‘).html(opts.emptyMsg || ‘no records‘).appendTo(vc);
d.css({
position:‘absolute‘,
left:0,
top:50,
width:‘100%‘,
textAlign:‘center‘
});
}
}
});

 

 $(‘#dg‘).datagrid({
   view: myview,
  emptyMsg: ‘no records found‘ });
