  I have an image within the itemtemplate of a RadListView. I'm populating several of the controls within the template on the ItemDataBound event for the ListView with the Entity Framework. I'm new to the Entity Framework so need some help in figuring out how to populate the RadBinaryImage control.
  
  The method I have for retrieving the image is this:
  
  

  public static byte[] GetAccommodationMainImage(int accomID)

  {

      byte[] image = null;

   

      using (var myEntity = new MyEntity1())

      {

          var photoRecord = (from accom in myEntity.WTO_Photos

                             where accom.accom_id == accomID

                             && accom.in_use_as_main == true

                             select accom).First();

          image = photoRecord.image;

      }

   

      return image;

  }

  Hello David,
  
  I'm assuming the Entity framework uses the same data type as Linq-to-SQL does when linking a VarBinary column, which I'm assuming is what your image column is. If so, the data type it uses is Binary. So to get the bytes from this field you can call photoRecord.image.ToArray().
  
  I hope that helps.
