title: manually maintain dirty cell marker on paging in Kendo grid
body: <p>I have an editable Kendo grid where I can edit a cell and the grid adds the red mark to the upper left hand corner of the cell. </p>
  
  <p>I go to another page and then come back to the page where the edit took place and the red mark is gone but the newly added value in the cell remains. I saw a response to this on the Kendo site where it was advised that: "In order to show the "dirty flag" every time the grid is rebound it will have to iterate through all the model, check all fields if changed and visible in the grid cells. " </p>
  
  <p>I'm assuming this will need to be done on the <code>DataBound()</code> event of the grid (seems to fire when I switch pages) where I will manually apply the <code>k-dirty-cell</code> class to the cell but I can't figure out how to make this work in code. Any thoughts are greatly appreciated.</p>
