I'm writing an asp.net user control. It has a property, FurtherReadingPage, and two controls bound to it: ObjectDataSource and a Repeater. Inside the Repeater I would like to display a hyperlink with an href property set to something like `FurtherReadingPage + "?id=" + Eval("Id")`. I don't know how to do it inside the page's markup. I can use `<% Eval("Id") %>` or `<% Response.Write(FurtherReadingPage + "?id=") %>` alone but I don't know how to mix them.
