Cgridview Pagination Error

Hi All,

I am implementing a filter analytics and my filter criteria includes, startdate, enddate, manager, country, region etc.

I have used CActiveDataProvider to collect the filtered data and CGridView to render the filtered result.

But i am having problem when i try to look next page in cgridview, it looses all the conditions on the data that i have applied and show me all the data.

My Model


 public function process()

        {

                $criteria = new CDbCriteria;

                $criteria->with[] = 'prospect';

                $criteria->together = true;

                $managercond = null;

                if($this->managers) {


                        $size = count($this->managers);

                        for($i = 0; $i < $size; $i++) {

                                if(!is_numeric($this->managers[$i])) {

                                        throw new CHttpException(400, 'Invalid values');

                                }

                                if($i) {

                                        $managercond .= 'OR ';

                                }

                        $managercond .= ' (t.assignedto='.$this->managers[$i].')';


                        }

                        $criteria->addCondition($managercond);

                }


                $calendercond = null;

                if($this->ts_calendarBegin) {

                        $calendercond = 't.tscreated >= '.$this->ts_calendarBegin;

                        $criteria->addCondition($calendercond);


                }


                $calendercond = null;

                if($this->ts_calendarEnd) {

                        $calendercond = 't.tscreated <= '.$this->ts_calendarEnd;

                        $criteria->addCondition($calendercond);

                }


        return new CActiveDataProvider('Query', array(

                        'criteria' => $criteria,

                        'pagination' => false,

        ));


        }



My Controller


 public function actionManagersearch()

        {

                $model = new Managersearchform;

                $dataProvider = $model->process();


                if(isset($_POST['Managersearchform'])) {

                        $model->attributes = $_POST['Managersearchform'];

                        if($model->validate()) {

                                $dataProvider = $model->process();

                                $mode = $_POST['Managersearchform']['submit'];

                        }

                }

                $this->render('managersearchform', array('model' => $model,

                        'dp' => $dataProvider

                ));


        }



My View


<div class="viewgrid">

<?php

        if ($dp) {

        echo "count = " . count($dp->getData());

        $this->widget('zii.widgets.grid.CGridView', array(
