title: How to change the default filter operator in angular Kendo Grid
body: <p>I'm using the angular version of Kendo grid, trying to change the default filter operator for "<strong>row</strong>" filter mode. </p>
  
  <pre><code>&lt;kendo-grid [data]="gridData" [sort]="state.sort" [filter]="state.filter"
          [sortable]="true" filterable="row" [loading]="loading" 
          (dataStateChange)="dataStateChange($event)&gt;
  &lt;/kendo-grid&gt;"
  </code></pre>
  
  <p><br>All the examples I found online is to change the default operator in "menu" filter mode, so is it possible to change the it in "<strong>row</strong>" filer mode?
  <br>For example in <a href="https://www.telerik.com/kendo-angular-ui/components/grid/filtering/" rel="nofollow noreferrer">Kendo's example</a>, the default operator for date type is "is after or equal to", but I'd like to change it to "is equal to", please suggest how to do that in "<strong>row</strong>" mode filter.</p>
  
  <p><br>
  Also how to add customized filter function for a column? 
  <br>For example, still "date" filter, I want to display the date + timestamp as the column value, but when filtering, I only want to compare the date part, how to do this?</p>
