I'm trying to understand !IsPostback.
Should I be using if(!IsPostBack) after a button click before submitting data to a SQL database like the following?
 protected void btn101_Click(object sender, EventArgs e)
       if (!IsPostBack)
           //insert into statement
Could this help prevent duplicate data entries which I have seen occasionally?

Thank you!
