title: Adding a non data bound row to a grid
body: <p>This is a bit of a blast from the past, but anyway...</p>
  
  <p>I have a grid, that loads from a store, with a rowselection model, and some buttons etc...</p>
  
  <pre><code>MyGrid = function(config){
      var config = Ext.apply({},config,{
      cm:'rowselection',
      store:new Ext.data.Store({
          ajax:true,
          url:'someUrl'
      })//thumbsucked config, this is prolly totally wrong
      });
  
      MyGrid.superclass.constructor.call(this, config);
  }
  Ext.extend(MyGrid,Extx.grid.GridPanel)
  </code></pre>
  
  <p>Now My question is...</p>
  
  <p>How do I add a row to this grid without actually adding it to the store?</p>
  
  <p>I want to do this so i can violate the column model ( eg I wanna add another row that has some textual info in it, and a hyperlink, which isn't gonna fit in my 4 column wide grid )</p>
  
  <p>Can I access it as a dataview or something?</p>
  
  <pre><code>this.store.on('load',function(store,records,e){
          doWhat()
          //debugger;
      },this);
  };
  </code></pre>
