the problem in here data: { id: @item.userprofileid }, . can not id in here although when show devtool chrome , see <a class="fa fa-times btn btn-danger btn-xs" data-ajax="true" data-ajax-method="get" data-ajax-success="showmodal()" href="/home/index/p000000002" id="bt_del_profile"> delete</a> can tell me this? , give me advices. thank you.

even though using @item.userprofileid within java script, it's asp.net. if had value coming javascript, use data: { id: '12345' },

which means code should data: { id: '@item.userprofileid' }. should fix problem.

some 'ideas'

you can change show modal this.

<div aria-hidden="true" class="modal fade mymodal"> <div class="modal-dialog">     <div class="modal-content">         <div class="modal-footer">             <button type="button" id="bt_del_ok" class="btn btn-success btn-sm">ok</button>         </div>     </div> </div>

then change showmodal below.

function showmodal(userprofileid) {     $(".mymodal").prop('id', userprofileid);     $(".mymodal").modal('show'); }

then in delete event;

 var userprofileid =  $(".mymodal").prop('id');  data: { id:userprofileid },
