Kevin,

You can just overload the constructor for the user form

Create a variable in the form
private int UserId = -1;

// constructor for the form with no id passed in
public frmUser()
{

}

// Constructor for the form with a userid passed in
public frmUser(int userId)
{
   this.UserId = userId;
}

public frmUser_Load(object sender, EventArgs e)
{
   if (this.UserId > -1)
   {
      // We are editing, so get call a function to get the data and bind it to the controls.
   } 
}

Now to use this from somewhere else all you need to do is initialize the form.
frmUser oUser = new frmUser();

or if you want to edit
frmUser oUser = new frmUser(id);
frmUser.ShowDialog();

Yes, that is what I would do as your controls could be bound to the dataset already. If you are adding, then just add a new row and make it the current row.

I hope that helps
