RadTooltip in Radgrid Child Table

[Leonard Jones]

I have an .aspx Content Page (i.e. a web page based on a master page), which contains a RadGrid with a single Child Table. I have used the following Telerik demo to incorporate a tooltip column into the child table http://demos.telerik.com/aspnet-ajax/tooltip/examples/targetcontrolsandajax/defaultcs.aspx. When I expand a row on the parent table I get the following error message

Microsoft JScript runtime error: Sys.WebForms.PageRequestManagerServerErrorException: Cannot find a server control with ID=ctl00_PageMainContent_gridFlightSchedule_ctl00_ctl07_Detail20_ctl04_targetControl. If you need to specify a client-side element ID, please set IsClientID to true.

I would be extremely grateful if you can you tell me what is happening here.
