title: Load jqGrid with filter already applied
body: <p>I've got a filter toolbar in my grid where I set some default values and after the filters are set I run the following code to refresh the content of the grid.</p>
  
  <pre><code>var gridDOM = this; // save $("#list")[0] in a variable
  if ($(this).jqGrid('getGridParam', 'datatype') === 'json') {
    // the first load from the server
    setTimeout(function () {
      gridDOM.triggerToolbar();
    });
  }
  </code></pre>
  
  <p>The problem with this is that the grid is loaded with all the data first, without any filters applied. This is producing a small "flash" when the filters are applied with the above code. </p>
  
  <p>What I want is to load the result of the filtering directly, and not with preloading the full content, and then present the filtered result.</p>
