title: how to make a column editable in kendo grid from a button click
body: <p>I've seen how you can make a column editable / non-editable within a kendo grid, but how do I make a certain column editable from a button outside the grid?</p>
  
  <p>The grid starts off as not editable but when a button is clicked outside the grid, it is to make "Column 2" editable. Can this be done?</p>
  
  <pre><code>&lt;button id="Edit"&gt;Edit&lt;/button&gt;
  &lt;div id="grid"&gt;&lt;/div&gt;
  
  $('#grid").kendoGrid({
      pageable: true,
      editable: false,
      etc...
      columns: [
         { field: "Column 1", title: "Column 1" }
         { field: "Column 2", title: "Column 2" }
         { field: "Column 3", title: "Column 3" }
      ]
  })
  </code></pre>
