c# - Eval can't access a nullable DateTime? -

Usually, on a foreach inside .ascx, I use a tap with the time of the correct date:

  & lt;% = item.DataModifica.Value.ToShortDateString ()%>   
 But if I tried it on a repeater:  
  & lt;% # Eval ("DataModifica.Value.ToShortDateString ()"). ToString ()% & gt;   
 I get an exception  
 
  There is no property with name in System.DateTime 'value'    
 Where am I wrong?   
 
 
 I recommend that you change the code like this:  
 < Code> & lt;% # convert ToDateTime (Eval ("DataModifica")). ToShortDateString ()% & gt;
