title: Kendo Grid custom filter on date
body: <p>I have seen a couple of code examples of how to do this, but none in the format I'm looking for. I tried to convert them myself, but without success. What I'm trying to do is to create a custom row filter that will give you an x-amount of options that can be used on a date.</p>
  
  <pre><code>columns.Bound(cc =&gt; cc.StartDate).Width(160)
     .HeaderHtmlAttributes(new { title = "startdate") })
     .Title("startdate"))
     .Filterable(ftb =&gt; ftb.Extra(false)
     .Operators(op =&gt; op.ForDate(d =&gt; d
     .IsEqualTo("At date")
     .IsLessThan("Before date")
     .IsGreaterThan("After date"))));
  </code></pre>
  
  <p>In the code above I'm trying to use filter options so a user can chose to filter events before, at and after a certain date. It would be nice if these options would actualy be shown and even better if a user could use the kendo datepicker. </p>
  
  <p>So my question is: What am I doing wrong that I'm not seeing the correct options and how do i get the date-picker into the filter?</p>
