Call C# method from JavaScript with parameter -

i want call c# method parameter javascript. possible, if remove parameter s of method <% showdetail(); %>

function showdetail(kurz)         {             string s = kurz.tostring();             <% showdetail(s); %>;         } 

c# methods test:

public void showdetail(string s)         {             label_test.text = s.tostring();         } public void showdetail()         {             label_test.text = "";         } 

it works fine without parameter s variable compiler error:

cs0103: name 's' not exist in current context

i have tried

showdetail(object s){....} 

and also

showdetail(string s){....} 

but not work.

create web method. that's easy , neat way of calling c# methods javascript. can call method using jquery ajax. see below example webmethod.

[webmethod] public static string registeruser(string s) {     //do stuff     return stringresult; } 

and call method using jquery ajax. can pass parameters also. given below

function showdetail(kurz) {  string sparam = kurz.tostring();      $.ajax({      type: "post",      url: "pagename.aspx/methodname",      data: "{s:sparam}", // passing parameter      contenttype: "application/json; charset=utf-8",      datatype: "json",      success: function(retvalue) {         // return value from.net method         }      });  }
