title: ReportViewerForMvc event on report load
body: <p>I am loading a report in an iframe using ReportViewerForMvc. Currently, I have a spinner so that the user will know the report is loading. However, the spinner stops spinning when the iframe is placed on the page...not when the content of the report is finished rendering. I have found people using isLoading with $find but I am pretty sure that is just for asp and I need my to be in .Net</p>
  
  <p><strong>What is the simplest way to have spinner continue to spin until the report is loaded in the iframe?</strong></p>
  
  <p>Currently, I have a shared view for all reports that I am hoping to add some javascript to: </p>
  
  <pre><code>@using ReportViewerForMvc;
  
  &lt;div id="reportViewer"&gt;@Html.ReportViewer(Model.ReportViewer as Microsoft.Reporting.WebForms.ReportViewer)&lt;/div&gt;
  </code></pre>
