ASP.NET Repeater Control + SUM

Quick summary.  

In my sql statement I am returning 8 values.
      
      ID
      Name
      Location
      RecordDate
      ReviewDate
      ReviewerName
      NumDates
      TotalDays
      

sql = "Select ID, Name, Location, RecordDate, ReviewDate, ReviewerName,  DATEDIFF(DAY, RecordDate, ReviewDate) AS NumDays,  "
sql = sql & "  SUM(DATEDIFF(DAY, RecordDate, ReviewDate)) AS TotalDays  from tblVendor  "

NumDays will equal the difference in days between the RecordDate and the ReviewDate.  
The TotalDays should SUM all the NumDays in the query.


Using the repeater control how do I display the SUM TotalDays in the footer ?  From the sample below everything works fine but when using Container.DataItem, "TotalDays" in the footer it does not display anything.

      <asp:Repeater ID="Repeater1" runat="server" >
        <HeaderTemplate>
        <table border = "0" cellpadding="3" cellspacing="1" >
        <tr>
        <th>ID</th>
        <th>Name</th>    
        <th>Location</th>
        <th>Date Received</th>
        <th>Reviewed By</th>
        <th>Date Reviewed</th>
        <th>Days Diff</th>  
                 
        </tr>
        </HeaderTemplate>
       
        <ItemTemplate>
        <tr>
        <td><%#DataBinder.Eval(Container.DataItem, "ID")%></a></td>
        <td><%#DataBinder.Eval(Container.DataItem, "Name")%></td>
        <td><%#DataBinder.Eval(Container.DataItem, "Location")%></td>
        <td><%#DataBinder.Eval(Container.DataItem, "RecordDate", "{0:d}")%></td>
        <td><%#DataBinder.Eval(Container.DataItem, "ReviewerName")%></td>
        <td><%#DataBinder.Eval(Container.DataItem, "ReviewDate", "{0:d}")%></td>
        <td><%#DataBinder.Eval(Container.DataItem, "NumDays", "{0:d}")%></td>    
        </tr>            
        </ItemTemplate>
        <FooterTemplate>        
        <tr>
        <td colspan="6">  
        </td>
        <td>[TotalDays should be displayed here] </td>
        </tr>  
        </table>
        </FooterTemplate>              
        </asp:Repeater>

Try playing around with this code:

http://www.experts-exchange.com/Web_Development/WebApplications/Q_23762786.html#a22570664

but instead of e.Item.ItemType = ListItemType.AlternatingItem Or e.Item.ItemType = ListItemType.Item

try  e.Item.ItemType = ListItemType.FooterItem

You have a bit of a weird scenario. I will do the following:
1. Put a label in the Footer
 <FooterTemplate>
             <asp:Label id="lblFooter" text="" runat="server" />
 </FooterTemplate>

2. Then retrieve and assign the label in the repeaters databound event
string sLocalValueToShowInFooter = "";

    protected void Page_Load(object sender, EventArgs e){}

    protected void Repeater2_ItemDataBound(object sender, RepeaterItemEventArgs e)
    {
      DataRowView drv = (DataRowView)e.Item.DataItem;
      if (drv != null)
      {
        sLocalValueToShowInFooter = drv["DataColumn3"].ToString();
      }

      if (e.Item.ItemType == ListItemType.Footer)
      {
        Label lbl = (Label)e.Item.FindControl("lblFooter");
        if (sLocalValueToShowInFooter != null)
        {
          lbl.Text = sLocalValueToShowInFooter;
        }
      }
    }

3. Resoning behind this is:
What row's value should be displayed in the footer? 1st,2nd last.
Also the local variable should probably be saved in viewstate in order not to loose value between postbacks.
So in this example I am retrieving a value to assign to the label control.

Sorry not the nicest example but it works.
