ASP.Net Core: Insert current DateTime in Database using Entity Framework

I have this form which submit successfully, I insert the values of the name text box into the createdby column in the database and also the datepicker textbox.

since I submit the value of the name as the createdby value I need to hide the createdby textfield and also hide the datepicker textbox since I will like to use current date

what I want

1) hide the createdby textfield from the form

2) hide the LastLoggedDate datepicker and insert current date
