title: Yii2 - Get filtered values
body: <p>I know this could be an unusual request but I hope someone can help me.</p>
  
  <p>In my gridview, I need to get the filter's values, for example, if I select a specific date to display at my gridview as filter, I want to get the date selected, my goal is to be able to make a query with all filters. I do not know if there is a way to do it.</p>
