How to call the confirmation two 2 times for confirmation to save the data in the database, with server validation or client validation in ASP C# Page?

I have a web page developed in ASP.NET with C# as the code behind. I am trying to save the records in the SQL Server Express edition. I need to ask for the confirmation of the user TWO (2) times.

I have some required fields on my page. I am doing the validation on server side, so, asking the confirm() on the OnClick of the SAVE button will not call the Validation events first.

Please suggest me a way to implement both; Validation and how to ask for confirmation TWO times?

Thanks in advance!
