Change the code like below.
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
DisplayUserDetails();

}
private void DisplayUserDetails()

dt.Rows.Add(1, "Project1", "Module1", "SubModule1", DateTime.Now, "Description1", "Remark1");

You need to call the below line on each postback to apply the responsive.
if (GridView1.Rows.Count > 0)
{
GridView1.HeaderRow.TableSection = TableRowSection.TableHeader;
}
