aspx:Included only the relevant parts of my markup as it is lengthy.

Hi Soumya,

I have tried to reproduce the error you experience, but to no avail. I'm sending you the code i tested at my end, which works perfectly fine. Please find the attachment.

Does the attached project work at your side? If yes - could you please modify it so we can see the problem locally?

Kind regards,
Nencho

Hi Nencho
Thanks for the reply.Even I am not getting the error .Tried different scenarios to remove the error,finally I just commented that part of the code and was working with other changes in the same code.But now with RadTabStrip1 & RadMultiPage1,the code works perfectly without showing any error.

Unfortunately I couldn't figure out the cause for the error.

Thanks,
Soumya
