title: GridOptions interface ag-Grid
body: <p>On ag-Grid <a href="https://www.ag-grid.com/javascript-grid-properties/" rel="nofollow noreferrer">documentation</a>, there is mentioned a lot about this <strong>GridOptions interface</strong>.</p>
  <p><a href="https://www.ag-grid.com/javascript-grid-properties/" rel="nofollow noreferrer">Grid Properties</a>, <a href="https://www.ag-grid.com/javascript-grid-events/" rel="nofollow noreferrer">Grid Events</a>, <a href="https://www.ag-grid.com/javascript-grid-callbacks/" rel="nofollow noreferrer">Grid Callbacks</a>, all 'claim' that</p>
  <pre><code>this options are available through the GridOptions interface
  </code></pre>
  <p>I managed to access, for example, the <em>columnDefs</em> property without any 'usage' of this <em>gridOptions</em>, by the following:</p>
  <h2>.html</h2>
  <pre><code>&lt;ag-grid-angular 
              style=&quot;margin: auto;
              width: 80%; height: 70%;
              #agGrid
              class=&quot;ag-theme-material&quot;
              [rowData]=&quot;rowData&quot; 
              [columnDefs]=&quot;columnDefs&quot;
              &gt;
  &lt;/ag-grid-angular&gt;
  </code></pre>
  <h1>.ts</h1>
  <pre><code>private columnDefs;
  
  constructor() {
      this.columnDefs = ...; // columns array
     }
  </code></pre>
  <p>However, I came to a point where i don't know how to integrate certain features without calling this gridOptions, like <a href="https://www.ag-grid.com/javascript-grid-api/#accessing-row-nodes" rel="nofollow noreferrer">accessing row nodes</a> provided by the api.</p>
  <p><strong>How can i mention / reach to this gridOptions?</strong></p>
