thank you!

in end solution

@{                 string value_d_s = "";                 datetime? dateornull = item.data_end_prezzatura;                 if (dateornull != null)                 {                     datetime date_d_s = dateornull.value;                     value_d_s = date_d_s.tostring("dd/mm/yyyy");                 }               }              <input type="datetime" id="data_end_@id" value="@value_d_s" />      

use overload of datetime.tostring() method format date.

<input type="datetime" id="data_end_@id" value="@item.data_end_prezzatura.tostring("dd/mm/yyyy")" /> 

if item.data_end_prezzatura string instead of datetime, need use datetime.tryparse():

@{     datetime test;     datetime.tryparse(item.data_end_prezzatura, out test); } <input type="datetime" id="data_end_@id" value="@test.tostring("dd/mm/yyyy")" /> 

note need handle case when tryparse fails.
