Question

I have two results from a data set. I want to add both results in one gridview column. I do not want to merge in the code behind. Is there another way to do that?

<asp:TemplateField HeaderText="Entered Date" SortExpression="Date">
                    <ItemTemplate>
                    <div style="text-align: center;">
                        <asp:Label ID="Label3" runat="server" Text='<%# formatDisplayDate(Eval("Date").ToString()) %>'></asp:Label>
                    </div>
                    </ItemTemplate>                    
                </asp:TemplateField>

Now i would return “04/04/2009”. I would like to return “04/04/2009-PASSED”

Have you tried:

formatDisplayDate(Eval("Date").ToString()) & "-" & Eval("OtherField").ToString()

If that doesn’t work you should be able to set up a TemplateField for the combined rows like this:

<asp:TemplateField HeaderText="CombinedFieldName" SortExpression="CombinedFieldName">
    <ItemTemplate>
       <asp:Label ID="Label1" runat="server" 
       Text='<%# DataBinder.Eval(Container,"DataItem.FirstField") %>' >
       </asp:Label>
       -
       <asp:Label ID="Label2" runat="server" 
       Text='<%# DataBinder.Eval(Container,"DataItem.SecondField") %>' >
       </asp:Label>
        </ItemTemplate>
</asp:TemplateField>

That said – it is usually much more efficient to do the field concatenation in the database operation if possible. I haven’t tested, but I would assume that concatenating in the SELECT would be fastest, followed by concatenating in the data set in the codebehind, and combining them on the ASP.Net page would be slowest.
