How to write an if in asp

Can some one help me to write this in asp? Is it possible?

               
                     <%# DataBinder.Eval(Container.DataItem, "Release" )%>
               
               
                    Text= '<%# if (bdirty) then DataBinder.Eval(Container.DataItem, "Release" )
                                 else GetDefaultRelease()%>'/>

Thank you!
