Forms Data Controls :: GridView DateDiff Negative Value

I have a GridView that populates the days between the start and end date. What i want to ask is that is it possible to display a word "Overdue" (If possible "Overdue by 7 days") when the datediff is negative (eg: -7 days) The following are parts my codes for now:

<asp:TemplateField HeaderText="Date Raised" SortExpression="DateRaised">
<ItemTemplate>
<asp:Label ID="Label1" runat="server" Text='<%# Bind("DateRaised","{0:d}") %>'></asp:Label>
</ItemTemplate>
</asp:TemplateField>
<asp:TemplateField HeaderText="Expected Close Date" SortExpression="DateClose">
<ItemTemplate>
<asp:Label ID="Label2" runat="server" Text='<%# Bind("DateClose","{0:d}") %>'></asp:Label>
</ItemTemplate>
</asp:TemplateField>
<asp:BoundField DataField="DaysTaken" HeaderText="Allocated Days" />
<asp:BoundField DataField="RemainingDays" HeaderText="Remaining Days" />
<asp:SqlDataSource ID="SqlDS_UnresolvedIssues" runat="server"
ConnectionString="<%&#36; ConnectionStrings:DatabaseConnectionString_PITLog %>"
SelectCommand="SELECT [IssueLog].[DateRaised], [IssueLog].[DateClose], DATEDIFF(dd,DateRaised,DateClose) AS DaysTaken, DATEDIFF(dd, GETDATE() ,DateClose) AS RemainingDays FROM [IssueLog]
INNER JOIN [ActDetails] ON [IssueLog].[ActID]=[ActDetails].[ActID] WHERE [ActDetails].[ProjID]=@ProjID AND [ActDetails].[DevPhase]=@DevPhase AND NOT [IssueLog].[IssueStatus]=@IssueStatus">
<SelectParameters>
<asp:ControlParameter ControlID="DD_PMProjID" Name="ProjID" />
<asp:ControlParameter ControlID="DD_DevPhase" Name="DevPhase" />
<asp:Parameter DefaultValue="COMP" Name="IssueStatus" />
</SelectParameters>
</asp:SqlDataSource>

By the way, I am using Web Developer 2008, VB.net.
