Display Event Notification Calendar like FaceBook using Repeater in ASP.Net

This way

  <asp:Repeater ID = "rptEvents" runat = "server" OnItemDataBound = "OnItemDataBound">
            <ItemTemplate>
                <asp:Label ID = "lblEvent" Text = '<%# Eval("Event") %>' runat = "server" />
                <asp:Label ID = "lblDate" Text = '<%# Eval("Date") %>' runat = "server" />
            </ItemTemplate>
            <SeparatorTemplate>
            <br />
            </SeparatorTemplate>
        </asp:Repeater>

I have made use of Dummy Datatable to populate repeater. You can directly bind it with the data from database. The important part is OnItemDataBound event

protected void Page_Load(object sender, EventArgs e)
    {
        DataTable dt = new DataTable();
        dt.Columns.AddRange(new DataColumn[2] { new DataColumn("Event"), new DataColumn("Date") });
        dt.Rows.Add("Event1", DateTime.Today);
        dt.Rows.Add("Event2", DateTime.Today.AddDays(1));
        dt.Rows.Add("Event3", DateTime.Today.AddDays(2));
        dt.Rows.Add("Event4", DateTime.Today.AddDays(3));
        rptEvents.DataSource = dt;
        rptEvents.DataBind();
    }
    protected void OnItemDataBound(object sender, RepeaterItemEventArgs e)
    {
        if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem)
        {
            Label lblDate = e.Item.FindControl("lblDate") as Label;
            DateTime dt = Convert.ToDateTime(lblDate.Text);
            if (dt.Date == DateTime.Today.Date)
            {
                lblDate.Text = "Today";
            }
            else if (dt.Date == DateTime.Today.AddDays(1).Date)
            {
                lblDate.Text = "Tomorrow";
            }
            else
            {
                lblDate.Text = dt.ToString("dddd dd, MM yyyy");
            }
        }
    }

 Output

Event1 Today Event2 Tomorrow Event3 Monday 27, 05 2013 Event4 Tuesday 28, 05 2013
