In the rowcreated I have the following code

bool Row = false;
if ((id != null) && (DataBinder.Eval(e.Row.DataItem, "id") != null))
{

if (id != (DataBinder.Eval(e.Row.DataItem, "id").ToString()))

Row = true;

}
if ((id != null) && (DataBinder.Eval(e.Row.DataItem, "id") == null))
{
Row = true;
rowIndex = 0;
}

if (Row)
{

GridView GridView1 = (GridView)sender;
GridView1.HeaderRow.BackColor = System.Drawing.Color.Orange;
GridViewRow NewTotalRow = new GridViewRow(0, 0, DataControlRowType.DataRow, DataControlRowState.Insert);
NewTotalRow.Font.Bold = true;
TableCell HeaderCell1 = new TableCell();
HeaderCell1.ColumnSpan = 6;
NewTotalRow.Cells.Add(HeaderCell);
HeaderCell1 = new TableCell();
HeaderCell1.HorizontalAlign = HorizontalAlign.Right;
HeaderCell1.Text = tohrs.ToString();
NewTotalRow.Cells.Add(HeaderCell1);
GridView1.Controls[0].Controls.AddAt(e.Row.RowIndex + rowIndex, NewTotalRow);
rowIndex++;
tohrs = 0;

}

Adding the solution given by OP hiself/herself.

In the RowCreated I have the following code

C#

bool Row = false;
if ((id != null) && (DataBinder.Eval(e.Row.DataItem, "id") != null))
{
    if (id != (DataBinder.Eval(e.Row.DataItem, "id").ToString()))
     
    Row = true;
    }
    
    if ((id != null) && (DataBinder.Eval(e.Row.DataItem, "id") == null))
    {
        Row = true;
        rowIndex = 0;
    }
     
    if (Row)
    {
        GridView GridView1 = (GridView)sender;
        GridView1.HeaderRow.BackColor = System.Drawing.Color.Orange;
        GridViewRow NewTotalRow = new GridViewRow(0, 0, DataControlRowType.DataRow, DataControlRowState.Insert);
        NewTotalRow.Font.Bold = true; 
        TableCell HeaderCell1 = new TableCell();
        HeaderCell1.ColumnSpan = 6;
        NewTotalRow.Cells.Add(HeaderCell);
        HeaderCell1 = new TableCell();
        HeaderCell1.HorizontalAlign = HorizontalAlign.Right;
        HeaderCell1.Text = tohrs.ToString();
        NewTotalRow.Cells.Add(HeaderCell1);
        GridView1.Controls[0].Controls.AddAt(e.Row.RowIndex + rowIndex, NewTotalRow);
        rowIndex++;
        tohrs = 0;
    }
}
