Gridview "Caption" styling from C # class

Question

I am trying to create an ASP.NET GridView header in a C # file. here is my method that returns a stylized gridview:

private GridView setupGridView(string caption)
{
 var gview = new GridView()
 {
  BackColor = Color.White,
  BorderColor = Color.Gray,
  BorderStyle = BorderStyle.Solid,
  BorderWidth = new Unit(1, UnitType.Pixel),
  Caption = caption,
  ForeColor = Color.Black,
 };
 gview.HeaderStyle.BackColor = Color.Navy;
 gview.HeaderStyle.ForeColor = Color.White;
 gview.HeaderStyle.BorderColor = Color.DarkGray;
 gview.HeaderStyle.BorderWidth = new Unit(1, UnitType.Pixel);
 gview.HeaderStyle.BorderStyle = BorderStyle.Solid;
 gview.AlternatingRowStyle.BackColor = Color.LightGray;
 return gview;
}

By default, Caption has no style (it's just black text on top of the gridview)

Does anyone know how I can style Caption Navy with white text? (similar to how, for example, I wrote a title bar?)

EDIT: I did this before using CSS, but I don’t have that option since it is a program that generates gridviews for sending via email. No aspx or skin file ...
