Need to Handle Transaction in web application, using webservice for DML operation

As per your given code suppose I have webmethods for Delete and Update too,
And I need to consume them(WebMethods) in my web application where I also have to handle Transaction,
Can you provide with example of codes while consuming method, transaction should also gets handle.
Since I cannot use connection.BeginTransaction in my Consuming application becoz connection part is run inside webmethod

e.g.

/Application Consuming Webmethod

try
{
//Here I need to handle Transaction if any error occurred in 
//middle of sth the transaction should get rolled back
service1.InsertRow(param1, param2);
service1.DeleteRow(param3, param4);
service1.UpdateRow(param5, param6);

}
Catch
{


}

web Service code...........

[OperationContract]
public string InsertRow(string empname,string designation)
  { 
  SqlConnection dbConn = null;
  dbConn = new  SqlConnection(System.Configuration.ConfigurationManager.ConnectionStrings["insightconnection"].ToString());
  
  SqlCommand cmd;
  SqlDataReader dr;
  
  dbcon.Open();
  spcmd = new SqlCommand("SP_InsertRow", spcon);
  spcmd.CommandType = CommandType.StoredProcedure;
  spcmd.Parameters.Add(new SqlParameter("@EMPName", empname));
  spcmd.Parameters.Add(new SqlParameter("@DEsignation", designation));

  dr = cmd.ExecuteReader();
  return "inserted......!!! ";
  }

Stored Procedure code..............

create PROCEDURE [dbo].[SP_InsertRow]
 
 @EMPName varchar(max),
 @DEsignation varchar(max)
AS
BEGIN
 SET NOCOUNT ON;

  insert into EMPDetails values(@EMPName,@DEsignation)
End
