I have autocomplete gridview which will filter when i keypress in separate textbox. It is working fine in filter part. but now i want to select the row from table and store the data in sessions. can anyone please explain how i can do it.

my jquery code is:-

$("#popup").ready(function () { GetCustomers(1);  });  $("[id*=txtSearch]").live("keyup", function () { GetCustomers(parseInt(1));  }); $(".Pager .page").live("click", function () { GetCustomers(parseInt($(this).attr('page'))); }); function SearchTerm() { return jQuery.trim($("[id*=txtSearch]").val()); }; function GetCustomers(pageIndex) { $.ajax({     type: "POST",     url: "Home.aspx/GetCustomers",     data: '{searchTerm: "' + SearchTerm() + '", pageIndex: ' + pageIndex + '}',     contentType: "application/json; charset=utf-8",     dataType: "json",     success: OnSuccess,     failure: function (response) {         alert(response.d);     },     error: function (response) {         alert(response.d);     } }); } var row; function OnSuccess(response) { var xmlDoc = $.parseXML(response.d); var xml = $(xmlDoc); var customers = xml.find("Customers"); if (row == null) {     row = $("[id*=gvCustomers] tr:last-child").clone(true); } $("[id*=gvCustomers] tr").not($("[id*=gvCustomers] tr:first-child")).remove(); if (customers.length > 0) {     $.each(customers, function () {         var customer = $(this);         $("td", row).eq(0).html($(this).find("Id").text());         $("td", row).eq(1).html($(this).find("Patient_First_Name").text());         $("td", row).eq(2).html($(this).find("Patient_DOB").text());         $("td", row).eq(3).html($(this).find("Patient_Home_Phone").text());         $("td", row).eq(4).html($(this).find("Patient_Account_No").text());         $("[id*=gvCustomers]").append(row);         row = $("[id*=gvCustomers] tr:last-child").clone(true);     });     var pager = xml.find("Pager");     $(".Pager").ASPSnippets_Pager({         ActiveCssClass: "current",         PagerCssClass: "pager",         PageIndex: parseInt(pager.find("PageIndex").text()),         PageSize: parseInt(pager.find("PageSize").text()),         RecordCount: parseInt(pager.find("RecordCount").text())     });      $(".ContactName").each(function () {         var searchPattern = new RegExp('(' + SearchTerm() + ')', 'ig');         $(this).html($(this).text().replace(searchPattern, "" + SearchTerm() + ""));     }); } else {     var empty_row = row.clone(true);     $("td:first-child", empty_row).attr("colspan", $("td", row).length);     $("td:first-child", empty_row).attr("align", "center");     $("td:first-child", empty_row).html("No records found for the search criteria.");     $("td", empty_row).not($("td:first-child", empty_row)).remove();     $("[id*=gvCustomers]").append(empty_row); } };
