Hey Everyone!

Hope you guys can help me with this. I am trying to format a datalist with the month name as headers. The issue I am facing is that the code is hiding some of the rows but I am unable to figure out why. The datasource returns 25 records without the ItemDataBound command and when I add the ItemDatabound code I get about 17 records. Basically if the name of the month is the same it should only display once and hide the duplicate month names. Here's what I have so far:
 protected void DataList1_ItemDataB(object sender, System.Web.UI.WebControls.DataListItemEventArgs e)

        if (e.Item.ItemType == ListItemType.AlternatingItem || e.Item.ItemType == ListItemType.Item)
            string strval = ((Label)(e.Item.FindControl("lblMP"))).Text;
            string month = ViewState["DateAdded"] as string;

            if (month == strval)
                ((Label)(e.Item.FindControl("lblMP"))).Text = "";
                e.Item.Visible = false;

                month = strval;
                ViewState["DateAdded"] = month;
                ((Label)(e.Item.FindControl("lblMP"))).Text = month;
                Panel pnlMonth = (Panel)e.Item.FindControl("pnlMonth");
                pnlMonth.Visible = true;
                e.Item.Visible = true;


Can someone please help out, thanks.
