Thanks for your reply.
In my real application, I'll be having several custom attributes for every
template column in my datagrid. On using hidden field for every of them will
result in increase in size of resulting HTML and in my opinion, using custom
attributes will be the most optimum solution.
I saw an article on codeproject sometime back which uses similar concept in
his VB.NET web application but I am not able to find that article now. So, I
can surely say that this type of behavior is not "impossible" for ASP.NET.
:-)
Any help will be appreciated for this problem.
