Handling Exceptions ObjectDatasource BLL to the user page

I have a problem to send the exceptions from BLL to the user page. when I try to insert data from the Detailsview this messag appear: "NullReferenceException was unhandled by the user code". How should I relate BLL to the Detailsview (user page)? I attached below the code for the BLL and user page.

BLL:

[System.ComponentModel.DataObjectMethodAttribute(System.ComponentModel.DataObjectMethodType.Insert, false)]
    public void InsertForestPhotos(int PhotoId, byte[] Photo, System.DateTime Date, string FileName)
    {

        try
        {
            AdapterForestPhoto.InsertForestPhotos(PhotoId, Photo, Date, FileName);
        }
        catch (Exception)
        {

            
        }

Detailsview code:

protected void ForestPhotoDetail_ItemInserted(Object sender, 
    DetailsViewInsertedEventArgs e)
  {
    

    // Use the Exception property to determine whether an exception
    // occurred during the insert operation.
    if (e.Exception == null && e.AffectedRows == 1)
    {
      // Use the Values property to get the value entered by 
      // the user for the CompanyName field.
      String name = e.Values["PhotoID"].ToString();
      //ExceptionDetails.Visible = true;
      // Display a confirmation message.
       ExceptionDetails.Text = name + " added successfully. ";

    }
    else
    {
      // Insert the code to handle the exception.
       ExceptionDetails.Text= e.Exception.Message;
       //ExceptionDetails.Visible = true;
      // Use the ExceptionHandled property to indicate that the 
      // exception is already handled.
      e.ExceptionHandled = true;

      // When an exception occurs, keep the DetailsView
      // control in insert mode.
      e.KeepInInsertMode = true;
         GridView1.DataBind();
    }
  }

Hello

Consider that your Photo is type of byte[]And it's not a standard typeI suggest you use a FileUpLoader to load the image and then use File.ReadAllBytes to set the property in the DetailsView_ItemUpdating event and do something like this

Plz see my sample at CodePlex
