You can use Repeater.ItemDataBound event to achieve this.

First, make sure you set the OnItemDataBound property to the name of the event handler method in your aspx code, let's say the name is rpt1_ItemDataBound:

<asp:Repeater ID="rpt1" runat="server" OnItemDataBound="rpt1_ItemDataBound">

then hide tdInfoHeader in rpt1_ItemDataBound method:

protected void rpt1_ItemDataBound(object sender, RepeaterItemEventArgs e)
{
    if (e.Item.ItemType == ListItemType.Header)
    {
        Label tdInfoHeader = (Label)e.Item.FindControl("tdInfoHeader");
        tdInfoHeader.Visible = false;
    }
}
