As you can see it is doubling by any reason the Magento fields pointed in the picture and the Loading block in the middle is not fading away.

Let me show you my entire config file:

Here is the files that is creating the grid table:

<?php

class VivasIndustries_SmsNotification_Block_Adminhtml_Sms_History extends Mage_Adminhtml_Block_Widget_Grid_Container


{
    public function __construct()
    {
        $this->_controller = 'adminhtml_sms_history';
        $this->_blockGroup = 'smsnotification';
        $this->_headerText = Mage::helper('smsnotification')->__('SMS History');

        parent::__construct();

        $this->_removeButton('add');
    }
}

And:

<?php

class VivasIndustries_SmsNotification_Block_Adminhtml_Sms_History_Grid extends Mage_Adminhtml_Block_Widget_Grid
{
    public function __construct()
    {
        parent::__construct();
        $this->setId('smsnotification_grid');
        $this->setDefaultSort('id');
        $this->setDefaultDir('DESC');
        $this->setSaveParametersInSession(true);
        $this->setUseAjax(true);
    }


    protected function _prepareCollection()
    {
        $collection = Mage::getResourceModel('smsnotification/smsnotificationhistory_collection');
        $this->setCollection($collection);
        return parent::_prepareCollection();
    }


    protected function _prepareColumns()
    {
          $this->addColumn('id', array(
              'header'    => Mage::helper('smsnotification')->__('ID'),
              'align'     =>'right',
              'width'     => '50px',
              'index'     => 'id',
          ));

          $this->addColumn('receiver', array(
              'header'    => Mage::helper('smsnotification')->__('Receiver'),
              'align'     =>'left',
              'index'     => 'receiver',
          ));

        $this->addColumn('phone', array(
            'header'    => Mage::helper('smsnotification')->__('Phone'),
            'align'     =>'left',
            'index'     => 'phone',
        ));

        $this->addColumn('email', array(
            'header'    => Mage::helper('smsnotification')->__('Email'),
            'align'     =>'left',
            'index'     => 'email',
        ));

        $this->addColumn('smstext', array(
            'header'    => Mage::helper('smsnotification')->__('SMS Text'),
            'align'     =>'left',
            'index'     => 'smstext',
        ));

        $this->addColumn('date', array(
            'header'    => Mage::helper('smsnotification')->__('Date'),
            'align'     =>'left',
            'index'     => 'date',
        ));



        return parent::_prepareColumns();
    }

    public function getRowUrl($row)
    {
        return $this->getUrl('*/*/edit', array('id'=>$row->getId()));
    }
}

I don't know where is my mistake and why it is doubling these fields. Do you have any idea how to resolve this problem ?

Thanks in advance!

Remove $this->setUseAjax(true).
