try this one is a very easy method if you are in list of model foreach  var item in Modal  loop    lt th href  quot  category edit  item idCategory gt View lt  a gt  quot    or   lt th href  quot  category edit  item idCategory quot  gt View lt  a gt

I think you can try this    lt a th href      category edit      category id    gt view lt  a gt    Or if you have  idCategory  this    lt a th href      category edit      category idCategory    gt view lt  a gt

I think your problem was a typo    lt a th href      category edit       category id    gt view lt  a gt    You are using category id  but in your code is idCategory  as Eddie already pointed out   This would work for you    lt a th href      category edit       category idCategory    gt view lt  a gt

Your code looks syntactically correct  but I think your property doesn t exist to create the URL   I just tested it  and it works fine for me    Try using category idCategory instead of category id  for example        lt tr th each  category     categories   gt       lt td th text    category idCategory   gt  lt  td gt       lt td th text    category name   gt  lt  td gt       lt td gt         lt a th href      category edit       category idCategory    gt view lt  a gt       lt  td gt     lt  tr gt
