Add Gridview Row AFTER Header

Question

i\'m trying to add a new headerrow to a Gridview. This row should appear below the original headerrow.

As far as I know I have two events to choose from:

1.)

Since this is a custom GridView, why don't you consider overriding the CreateChildControls method?

I.e (sorry, C#):

protected override void CreateChildControls()
{
    base.CreateChildControls();

    if (HeaderRow != null)
    {
        GridViewRow header = CreateRow(-1, -1, DataControlRowType.Header, DataControlRowState.Normal);
        for (int i = 0; i < Columns.Count; i++)
        {
            TableCell cell = new TableCell();
            cell.Text = Columns[i].AccessibleHeaderText;
            cell.ForeColor = System.Drawing.Color.Black;
            cell.BackColor = System.Drawing.Color.Cornsilk;
            header.Cells.Add(cell);
        }

        Table table = (Table)Controls[0];
        table.Rows.AddAt(1, header);
    }
}

UPDATE As was mentioned by Ropstah, the sniplet above does not work with pagination on. I moved the code to a PrepareControlHierarchy and now it works gracefully with pagination, selection, and sorting.

protected override void PrepareControlHierarchy()
{
    if (ShowHeader && HeaderRow != null)
    {
        GridViewRow header = CreateRow(-1, -1, DataControlRowType.Header, DataControlRowState.Normal);
        for (int i = 0; i < Columns.Count; i++)
        {
            TableCell cell = new TableCell();
            cell.Text = Columns[i].AccessibleHeaderText;
            cell.ForeColor = System.Drawing.Color.Black;
            cell.BackColor = System.Drawing.Color.Cornsilk;
            header.Cells.Add(cell);
        }

        Table table = (Table)Controls[0];
        table.Rows.AddAt(1, header);
    }

    //it seems that this call works at the beginning just as well
    //but I prefer it here, since base does some style manipulation on existing columns
    base.PrepareControlHierarchy();
}
