title: jqgrid add custom button to nav layer to go to new page
body: <p>OK, I am using jqgrid to only display a subset of information.</p>
  
  <p>I want to use a custom button in the nav layer to navigate to a new page where the user can enter a new record.</p>
  
  <p>i.e. I want a button that says (New record" which, when clicked loads a new pagewhich contains my record input form and code.</p>
  
  <p>I can create the bvutton fine, but I can't seem to find the right way to get it to call a function which loads a new page.</p>
  
  <p>Any ideas??</p>
