Hi suppose this binding : <asp:Label runat="server" Text='<%# MyFunction( (DateTime) DataBinder.Eval(Container,"DataItem.ExpireDate")) %>' ID="Label1"></asp:Label> which MyFunction is a function with a DateTime parameter and string result. The problem is here: the field ExpireDate can have SQL NULL value and this with throw an exception because of invalid type casting (NULL to DateTime). What should I do to avoid this exception? Thanks Ramtin K.
