title: How to load a partial view inside Kendo Window on request
body: <p>I have a kendo window who's data is loaded with an ajax call. This kendo window is acting like a widget editor which allow users to change or manipulate data in order to render different charts etc. Once users have configured all the options they want to preview their chart/graph before being displayed on a page.
  I have successfully constructed the model window and loaded the initial data with one input (Preview) button but now I don't know how to load the partial view inside the Model window on the Preview button click. I don't know if this approach is right or not but I defiantly need a partial view as I have to construct the model which will be passed to this partial view to render the chart/graph.</p>
  
  <pre><code>    $('.btnedit').click(function () {
          var pwrid = $(this)[0].id;
  
          $.ajax({
              url: '/Home/EditWidget/' + '?id=' + pwrid,
              type: 'GET',
              accepts: 'text/html',
              context: self,
              success: self.editWidgetWindowCallBack,
              error: function () { alert('Oops! Something went wrong'); },
              complete: function(){ }
          });
      });
  
  editWidgetWindowCallBack: function (html, textStatus, jqXHR) {
      var model = $('#EditWidgetModelWindow').data('kendoWindow');
      model.content(html);
      model.center();
      model.open();
  }
  </code></pre>
  
  <p>EditWidgetModelWindow is my kendo model window</p>
  
  <p>following is my action method</p>
  
  <pre><code>public ActionResult EditWidget(string id)
  {
      var widgetViewModel = // view model construction here.
      return PartialView("Widgets/_EditWidget", widgetViewModel);
  }
  </code></pre>
  
  <p>this is how my kendo model window is loading an editor partial view in it and now I want to load another partial view inside this partial view on a button click.
  e.g. if my partial view name is _Chart and model name is ChartModel, how I can call this partial view from the parent partial view on a button click (on demand) and render it inside the existing partial view with in the Kendo Model Window.</p>
