title: Binding checkboxes in treeview with checkboxes that uses remote datasource
body: <p>Let me layout a situation here. I have a situation where I need to show several check boxes on a form that are hierarchical by nature in terms that some of them belong to one category and other belong to a second and so on. My first idea was to use KendoUI treeview with check boxes.
  I have several questions in relations to this: </p>
  
  <ol>
  <li>obviously there will be a situation where on a form load some check boxes need to be checked because they are coming like that from data source. When I define new kendo.data.HierarchicalDataSource there is a property that lets me specify what property in the data source defines hierarchy, 'ParentID', and another that notifies if particular item has any children items 'hasChildren'. I cannot see if there is a property called 'checked' or something that would allow proper binding with the data source in the same fashion. <strong>Does one exist and how do I set that up</strong>?</li>
  <li>Provided that the answer to the first question is NO, what I did so far is manually check individual check boxes in treeview's dataBound event like this:</li>
  </ol>
  
  <pre class="lang-js prettyprint-override"><code>    $(e.node).find(":checkbox[isselected='true']").prop("checked", true);
  </code></pre>
  
  <p>What this does is go through the check boxes in the node and checks if they have an attribute called 'isselected' (which I fill by using a check box template) and if that one is set to <code>true</code> then check that check box. This works as it should but the problem happens when I want to post the checked boxes back to the server. The check boxes selected through above code are not reflected in the treeview's datasource. Now I have to figure out on how to do that. I was wandering if there was a more elegant solution to this instead of the approach I am using: manually check the check boxes -> fire event on every check box to update its 'isselected' attribute or treeview datasource -> on posting values get all of the checked values.</p>
  
  <p>Thanks for any help.</p>
