Please try to run the code below:
$('#pg').propertygrid({
onBeginEdit:function(index,row){
var pg = $(this);
var ed = pg.propertygrid('getEditors',index)[0];
var t = $(ed.target).hasClass('textbox-f') ? $(ed.target).textbox('textbox') : $(ed.target);
t.select();
t.bind('keydown',function(e){
if (e.keyCode == 9){
pg.propertygrid('endEdit', index);
if (index < pg.propertygrid('getRows').length-1){
pg.propertygrid('beginEdit', index+1);
return false;
}
}
})
}
})
