CompaniesController.php

public function actionCompanyinfo(){     

$text_in_search = $_GET['text_in_search'];
$left_items_cat = ltrim($_GET['left_items_cat']);

if($left_items_cat == "Companies"){

     $dataProvider= (new \yii\db\Query())
            ->select(['c.name', 'c.id'])
            ->from(['companies as c'])
            ->where('c.name LIKE :query') 
            ->addParams([':query'=>'%'.$text_in_search.'%'])
            ->all(); 

    return $this->renderPartial('gridview', [
        'dataProvider' => $dataProvider,
    ]); 

}}

You need to render the gridview in gridview.php view file

myjsfile.js

$("#getinfo").click(function(){
    var text_in_search = $("#companies-name").val();
    var left_items_cat = $('#left-items li.active').text();
    var url = "index.php?r=companies/companyinfo";

    $.ajax({
    url: url,
    method: 'GET',
    data: {text_in_search,left_items_cat},
    success: function (data, textStatus, jqXHR) {           
         //set the ajax response as your html content 
         $('#myDiv').html(data);
    },
    error: function (jqXHR, textStatus, errorThrown) {
        console.log('An error occured!');
        alert('Error in ajax request');
    }
});

You could render and return HTML of the Gridview from your controller, and then when you get the response. put the HTML code where you want to display it, probably where the current Gridview is contained.

Edit, added code example:

public function actionCompanyinfo(){
    $requestData = \Yii::$app->request->get();
    $text_in_search = isset($requestData['text_in_search']) ? $requestData['text_in_search'] : "";
    $left_items_cat = isset($requestData['left_items_cat']) ? trim($requestData['text_in_search']) : "";

    if($left_items_cat == "Companies"){
        $dataProvider = new ActiveDataProvider([
            'query' => (new \yii\db\Query())
            ->select(['c.name', 'c.id'])
            ->from(['companies as c'])
            ->where('c.name LIKE :query')
            ->addParams([':query'=>'%'.$text_in_search.'%']),
            'pagination' => [
                'pageSize' => 20,
            ],
        ]);

        return \yii\grid\GridView::widget([
            'dataProvider' => $dataProvider,
            'columns' => [
                ['class' => 'yii\grid\SerialColumn'],
                // your columns here...
                ['class' => 'yii\grid\ActionColumn'],
            ],
        ]);
    }
}

On your VIEW file you should create an area (possible element And then in your js file where you are making the AJAX request, make sure the response does something like:

function (data, textStatus, jqXHR) {           
    $("#show-grid-here").html(data); //or data[0], I'm not sure. try both.
},
