title: RadComboBox SelectedIndexChanged event not firing when using inplace editing in a RadGrid
body: <p>I am using inplace editing on a RadGrid that is built using a class file. Everything is working well except I am having an issue the SelectedIndexChanged event not firing when the grid is in edit mode. Any thoughts?</p>
  
  <pre><code>private void RadGrid_ItemCreated(object sender, GridItemEventArgs e)
  {
      if (e.Item is GridEditableItem &amp;&amp; e.Item.IsInEditMode)
      {
          try
          {
              if ((e.Item as GridDataItem) == null) { return; }
              ((RadNumericTextBox) (e.Item as GridDataItem)["Percentage"].Controls[0]).Width = Unit.Pixel(75);
              ((TextBox) (e.Item as GridDataItem)["Code"].Controls[0]).Width = Unit.Pixel(75);
  
              RadComboBox _participantList = (e.Item as GridEditableItem)["ID"].Controls[0] as RadComboBox;
              if (null == _participantList) { return; }
  
              _participantList.Width = Unit.Pixel(120);
              _participantList.DataValueField = "ID";
              _participantList.DataTextField = "ID";
              _participantList.AutoPostBack = true;
              _participantList.DataSource = MAASBaseInterface.ParticipantAPI.GetParticipants();
              _participantList.DataBind();
              _participantList.SelectedIndexChanged += new RadComboBoxSelectedIndexChangedEventHandler(_participantList_SelectedIndexChanged);
  
              if (!(e.Item.DataItem is GridInsertionObject))
                  _participantList.SelectedValue = ((Participant) (e.Item.DataItem)).ID.ToString();
              if (e.Item.DataItem is GridInsertionObject)
                  _participantList.EmptyMessage = "-- Select --";
          }
          catch (Exception ex)
          {
  
              string _ex = ex.Message;
          }
      }
  } 
  
  void _participantList_SelectedIndexChanged(object sender, RadComboBoxSelectedIndexChangedEventArgs e)
  {
      //first reference the edited grid item through the NamingContainer attribute
      GridEditableItem editedItem = (sender as RadComboBox).NamingContainer as GridEditableItem;
      int _selectedValue = Convert.ToInt32((editedItem["ID"].Controls[0] as RadComboBox).SelectedValue);
      ParticipantList _participants = MAASBaseInterface.ParticipantAPI.GetParticipants();
      Participant _participant = _participants.Where(a =&gt; a.ID == _selectedValue) as Participant;
      RadTextBox _code = editedItem["Code"].Controls[0] as RadTextBox;
      _code.ReadOnly = false;
      _code.Text = _participant.Code;
  }
