c# - How to pass and retrieve table row data using QueryString in asp.net -

i have datatable

i have created

var a=[]; $("#datatable tbody").on( 'click', 'tr', function ()  {            a=table.row( ).data(); }); 

now want pass array a[] web form using query string on button click

<asp:button id="button" onclick="click_function"/> 

and then

[webmethod] click_function()           {           var darr = [];           darr = table.row('.selected').data();            var url = "questiondetail.htm?questionid=" + darr;           window.location.href = url;           } 

how should i?

and have retrieve array in new webform. so, data of row

i'm guessing

// javascript     var table = $("#datatable").datatable(); 

if that's case add hidden field on form

<!-- html --> <input type="hidden" runat="server" id="hfselectedrow" /> 

and set data field

// javascript $("#datatable tbody").on( 'click', 'tr', function ()  {            $('#hfselectedrow').val(table.row( ).data()); }); 

so on server can retreive data by

[webmethod] protected void button_click()  {     response.redirect("questiondetail.htm?questionid=" + hfselectedrow.value); }
