I want to display gridview in horizontal format in C# and Vb.Net.

I want to display my image from the database in horizontal format but GridView does not allow what I want. How do I change my code to suit how I want my images to display.

ASPX

<asp:GridView ID="gvImages" runat="server" AutoGenerateColumns="false" OnRowDataBound="OnRowDataBound">
    <Columns>
        <asp:BoundField HeaderText="File Name" DataField="image_name" />
        <asp:TemplateField HeaderText="image">
            <ItemTemplate>
                <asp:Image ID="Image1" runat="server" Height="80" Width="80" />
            </ItemTemplate>
        </asp:TemplateField>
    </Columns>
</asp:GridView>

 CS

protected void Page_Load(object sender, EventArgs e) 
{
   if (!IsPostBack) 
   {
    this.BindGrid();          
   }
}

private void BindGrid() 
{
  MySqlConnection connection = new MySqlConnection(xxxxxxx)
  
  using (MySqlCommand cmd = new MySqlCommand())
  {
    cmd.CommandText = "SELECT * FROM annexa_images";
    cmd.Connection = connection;
  
    using (MySqlDataAdapter dr = new MySqlDataAdapter(cmd))
    {
      DataTable dt = new DataTable();                    
      dr.Fill(dt);
      gvImages.DataSource = dt; //GridView ID
      gvImages.DataBind(); //GridView ID
    }
}

protected void OnRowDataBound(object sender, GridViewRowEventArgs e) 
{
  if (e.Row.RowType == DataControlRowType.DataRow)
  {
    byte[] bytes = (byte[])(e.Row.DataItem as DataRowView)["image"];
    string base64String = Convert.ToBase64String(bytes, 0, bytes.Length);
    (e.Row.FindControl("Image1") as Image).ImageUrl = "data:image/png;base64," + base64String;
  }
}
