Page fails to load when arraylist being saved in Viewstate

Question

Hi, I'm facing problem when i load page with dynamically created controls. This happens if i save a arraylist in viewstate. ViewState["Delim"] = arrList; I searched the net, and found that we can save arraylists in viewstate, and that try saving it in page_preRender. I did so, but same issue. If i save some string in viewstate instead, it doesn't have any problems loading the dynamic controls. Anyone can help me here, to resolve this? Thanks, Deepa
