Hello, I have three widgets in my nterms.php view:

//widget1
<?php $form=$this->beginWidget('CActiveForm', array(
	'id'=>'form',
	'action'=>$this->createUrl('terms/nterms'),
	'method'=>'get',
	'enableAjaxValidation'=>false,
	'htmlOptions'=>array('name'=>'filterForm'),
)); ?>
	<p>
	<?php echo CHtml::radioButton('Form_select', (isset($_GET['Form_select']) && $_GET['Form_select'] == 'yesterday'), array('value'=>'yesterday')); ?>
	<?php echo Yii::t('main', 'Yesterday'); ?>
	<?php echo CHtml::radioButton('Form_select', (isset($_GET['Form_select']) && $_GET['Form_select'] == 'today'), array('value'=>'today')); ?>
	<?php echo Yii::t('main', 'Today'); ?>
</p>
	<?php echo CHtml::submitButton(Yii::t('main', 'OK')); ?>
<?php $this->endWidget(); ?>

<?php echo CHtml::button('Print', array('submit' => array('terms/nterms', 'redir'=>'printpdf'))); ?>

//widget2
<?php $this->widget('zii.widgets.grid.CGridView', array(
	'id'=>'terms-grid',
	'dataProvider'=>$dataProvider,
	'filter'=>$model,
	'columns'=>array(
		array(
			'name'=>'datetime',
			'type'=>'raw',
			'value'=>'date("Y-m-d H:i", strtotime($data->datetime)),
			'visible'=>true,
		),
		array(
			'name'=>'userName',
			'type'=>'raw',
			'value'=>'$data->user->fullname',
			'visible'=>true,
		),
    		array(
			'class'    => 'CButtonColumn',
			'buttons' => array(
                          .....
                ),
        )
));

if (isset($_GET['redir']) && $_GET['redir']=='printpdf')
{
ob_clean();

//widget3
$this->widget('ext.pdfGrid.EPDFGrid', array(
    'id'        => 'informe-pdf',
    'fileName'  => 'Pdf',//Nombre del archivo generado sin la extension pdf (.pdf)
    'dataProvider'=>$dataProvider,
    'columns'   => array(
		array(
			'name'=>'datetime',
			'type'=>'raw',
			'value'=>'date("Y-m-d H:i", strtotime($data->datetime)),
			'visible'=>true,
		),
		array(
			'name'=>'userName',
			'type'=>'raw',
			'value'=>'$data->user->fullname',
			'visible'=>true,
		),
        ),
     'config'    => array(
        'title'     => 'Pdf',
	'subTitle'  => 'Pdf',
        'colWidths' => array(50, 50),
    ),
));
}

When I filter data in the table, I generate pdf with filtered data. If I choose Today on radiobutton and click OK, the table displays correct data (records with today day). In addition I can sort and filter in the table these displayed data.
When I print pdf, pdf displays data with operations that were made in the table, it does not take data from radiobutton.

widget1 -> widget2
widget2 -> widget3
widget1 NOT -> widget3

How can I send data from radiobuttons to pdf? How can I integrate these three widgets?

Regards
