I have a template data field in a WebDataGrid.  In the template is a button and when the user clicks on the button, I want to display the contents of a hidden column (I do not want to go back to the server for this data).  I have this code for my template field:

                            <ig:TemplateDataField Key="NotesButton">

                                <ItemTemplate>

                                 <input runat="server" type="button" value="Notes"  onclick="BLOCKED SCRIPTShowNotes()" /> 

                                <asp:Button runat="server" Text="asp but" OnClientClick="BLOCKED SCRIPTShowNotes()" />

                                </ItemTemplate>

                            </ig:TemplateDataField> 

  And the following for my Javascript.

                      function ShowNotes(webDataGrid, evntArgs) {

                          var grid = $find("<%= grdSchedule.ClientID %>");

                          var activeRow = grid.get_behaviors().get_activation().get_activeCell().get_row();

                          alert(activeRow.get_cell(0).get_value());

                          return false;

                      }

The event fires but i suspect that there is no active row since there is no row selected.  How do i get the data from a cell of the row that contains the templated data field without making the user select the row first?

Thanks
