Hi,

Is it possible to call a method in the JavaScript?

The method is not a web method.i.e please look the method bellow

C#

public static string LoadData()
  {
      SqlConnection cn = new SqlConnection(ConfigurationManager.ConnectionStrings["conn"].ConnectionString);
      SqlDataAdapter da = new SqlDataAdapter("select * from Employee", cn);
      DataSet ds = new DataSet();
      da.Fill(ds);
      return JsonConvert.SerializeObject(ds.Tables[0]);
  }

I need to call this method in script. I have done with we method but our manager is not accepting because If we declare method as a web method it exposed so that I need to call direct method in script i.e JQGrid Script.Please look the script

JavaScript

<pre lang="cs">$(document).ready(function () {
                        $.ajax({
                url: "Default1.aspx/LoadData",

                                                           drag: false
                                                       });
                   
                }
                
            });
            
        });</pre>

If You don't Know the jqGrid leave it the jqGrid script. In general script how we can call.

you can call static method like this.. :)

Default1.aspx

JavaScript

$(document).ready(function () {
  $.ajax({
        type: "POST",
        contentType: "application/json; charset=utf-8",
        url: "Default1.aspx/LoadData",
        data: DataValue,
        dataType: "json",
        success: function (data) {

          alert("Success");

        },
        error: function (result) {

          alert("error");

        }
    });
});

Default1.aspx.cs

C#

    [WebMethod]
public static string LoadData()
   {
       SqlConnection cn = new SqlConnection(ConfigurationManager.ConnectionStrings["conn"].ConnectionString);
       SqlDataAdapter da = new SqlDataAdapter("select * from Employee", cn);
       DataSet ds = new DataSet();
       da.Fill(ds);
       return JsonConvert.SerializeObject(ds.Tables[0]);
   }
