Forms Data Controls :: Trying To Use Dynamic Object In A Databinding Tag

im trying to use dynamic object in a databinding tag , it gives me error that the property does not exists even though i can see all the properties there in the vs debug mode

here is what im trying to do:

C#:

my method signature:

public static dynamic MyMethod()

ASPX:

in control itemtemplate:

<%# MyMethod().SomeProperty %>

if also trite the other way:

C#:

public static object MyMethod()

ASPX:

<%# ((dymanic)MyMethod() ).SomeProperty%>

But i dont know why it cant resolve the properties , even though i can see them when the databinder control throws an exception (its working fine outside the databinder tag (ie normal aspx tags <% %>)
