Add LinkButtons during OnDayRender event of ASP.NET Calendar Control

So I need to add some link buttons to each cell of a asp:calendar control dynamically based on data in the database. I wondering what the best way to do this is so that the the link buttons will be wired up to their events on postbacks (as to my knowledge creating the link buttons on the Day Render event and adding them there will occur after the LinkButton events would have fired).

How to bind a List to a gridview?

This might be quite a strange question since usually people bind only complex types to a gridview. But I need to bind a List of Int (the same is for strings).
Usually, as the property to bind one uses the name of the property of the object, but when using a Int or a String, the value is exactly the object itself, not a property.
