Hi JayKumar, You cannot directly call any server-side methods from the client end. I don't aware about what kind of application you are working on but If you want to do, we can have two options. Option-1: You need to call this method via Ajax call from Client End using $.Ajax or other techniques. Option-2: You can create HTTP handler file (.ashx) and call this file using Ajax call from the front end. Option-3: You can even call any server-side methods using SignalR. Here I am trying to give you what options can fulfill your requirement to call a server-side method. If you select any one option which suits your application. Surely I can help you by providing some samples.

$(document).ready(function() { //set initial state. $('#textbox1').val(this.checked); $('#checkbox1').change(function() { if(this.checked) { var returnVal = confirm("Are you sure?"); $(this).prop("checked", returnVal); } $('#textbox1').val(this.checked); }); });
