First of all, this issue is not related to any animation feature of RadGrid. I am afraid that I was not able to reproduce the same issue on my side. Could you provide a sample runnable project that is isolating the issue
. Meanwhile, please check if some custom css is not messing up the alignment of the checkboxes. Any further information will be very helpful, like in which browser do you face the issue, which version of the controls do you use and so on.
I look forward to your reply.
