You need to check whether page is postback. Put your database insertion code inside following condition.

if(!IsPostback)
{

}

Use a hidden field. Check the value of the field before you do the insert. If the field is blank, do the insert and set hidden field value to "inserted", else don't insert.

After saving the information in database simply redirect to the current page. For instance, if your page name is insert.aspx then after saving the record write : Response.Redirect("insert.aspx"); This will prevent the page from raising postback on refresh.
