Method 1

You might add code to the rowdatabound-event of your grid:

protected void GridView_RowDataBound(object sender, GridViewRowEventArgs e)
{
    if (e.Row.RowType == DataControlRowType.DataRow)
    {
        GridViewRow row = new GridViewRow(e.Row.RowIndex, 0, DataControlRowType.Header, DataControlRowState.Normal);

        TableCell cell = new TableCell();
        cell.Controls.Add(new Label { Text = "Header" }); //as needed

        row.Cells.Add(cell);

        Table tbl = (e.Row.Parent as Table);

        tbl.Controls.AddAt(e.Row.RowIndex * 2 + 1, row);            
    }
}

In this example, I have removed the gridview header altogether as you write your own in code behind.

Method 2

You can’t without re-writing the control render method. How about using a repeater and putting it in the item separator element too?

Method 3

Well, it is way easier to either put the markup for the header also in the item template. Overriding the Render method for something like this is probably overkill.

But if there is a reason to do this, it is at least missing from your question.

Method 4

If you need the header row markup in every single item row, why not just include the markup that is currently in your header into the ItemTemplate …?
