title: Cannot implicitly convert type 'System.DateTime?' to 'System.DateTime'. An explicit conversion exists (are you missing a cast?)
body: <p>I think I am suppose to use something like this but I am not sure how to modify it to work for DateTime because upon doing so it tells me DateTime can not be null. So how can I change this or is there a better method to resolve this issue? Thank you in advance.</p>
  
  <p>What I'm trying to set</p>
  
  <pre><code>startDateTime = RadDateTimePickerBegin.SelectedDate;
  </code></pre>
  
  <p>What I think it should look similar to</p>
  
  <pre><code>RadDateTimePickerBegin.SelectedDate == What goes here(string.Empty) ? (object)DBNull.Value : RadDateTimePickerBegin.SelectedDate);
  </code></pre>
