Forms Data Controls :: Adding Static Text Before Bind() In Datalist Control?

I have a datalist control

In it, I have a hyperlink that im binding the url, and the text to from a mysql database

here is my code so far

<asp:HyperLink ID="HyperLink1" runat="server"
NavigateUrl='<%#Bind("topicid") %>' Text='<%# Bind("title") %>'></asp:HyperLink>

Now, the problem is, the field "topicid" returns a number, such as 3. I want to add the following text before it: viewTopic.aspx?id=

So, ideally, i want something like this

<asp:HyperLink ID="HyperLink1" runat="server"
NavigateUrl='<%# "viewTopic.aspx?id=" + Bind("topicid") %>' Text='<%# Bind("title") %>'></asp:HyperLink>

But, when I do it that way, I obviously get an error.

So, is there any way to solve this problem without having to modify the database?
