title: Persist additional dataSource.read parameters on paganation in Kendo data grid
body: <p>I have a Kendo Grid that loads data via ajax with a call to server-side ASP.NET read method:</p>
  
  <pre><code> public virtual JsonResult Read(DataSourceRequest request, string anotherParam)
  </code></pre>
  
  <p>In my client-side JS, I trigger a read when a button is clicked:</p>
  
  <pre><code>grid.dataSource.read( { anotherParam: 'foo' });
  grid.refresh();
  </code></pre>
  
  <p>This works as expected, only I lose the additional param when I move through the pages of results in the grid, or use the refresh icon on the grid to reload the data.</p>
  
  <p>How do I persist the additional parameter data in the grid?</p>
  
  <p>I have tried setting</p>
  
  <pre><code>grid.dataSource.data
  </code></pre>
  
  <p>directly, but without much luck. I either get an error if I pass an object, or no effect if I pass the name of a JS function that returns data.</p>
