Load on Demand

I have a webhierarchicaldatagrid with two child grids, the intialdatabinddepth is 0 and the child grids are expanding/loading on demand. However, I have a search functionality on my web page which searches the text in all the grids. Through a stored procedure I am getting the search results with ID's for all the grids (parent and child). If a click on any search result I want that webhierarchicaldatagrid row to be expanded with the search text to be highlighted. For parent row its working fine, but for child grid I am first finding the parent row id then binding the child grid and then expanding and highlighting that particular text. But I am getting this error: . Is there a way I can bind only the child grids I want and implement the search functionality. Please help, its very urgent.

Thanks.
