xaml.cs

 var varexp = exp in empdb.expense                              join cat in empdb.category                              on exp.categoryid equals cat.categoryid                              select new { exp.expenseid, exp.date, exp.price, exp.description, cat.name };                 foreach (var item in varexp)                 {                     string[] formats = { "dd/mm/yyyy" };                     expensevo objexpense = new expensevo();                                            string strdate = item.date.tostring("dd/mm/yyyy");                                             objexpense.date = datetime.parseexact(strdate, formats, new cultureinfo("en-us"), datetimestyles.none);                      objexpense.price = item.price;                     objexpense.categoryname = item.name;                     expenselist.add(objexpense);                 } 

you can format text property:

text="{binding date, stringformat='dd/mm/yyyy'}"
