ModalPopupExtender not working correctly?

Since You have use RequiredFieldValidator so these are on when you click OK button, You have to Set CausesValidation="false" or use use ValidationGroup.

If you really need validation in modal popup use javascript / jquery .

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
