    The function gets Fired Twice why ?

    Good Day All

    i have a function that is getting called with Page-methods like this

    Code:
      protected void Bind_SearchBox(object sender, EventArgs e)
        {
            
                RadToolBarItem textItem = RadToolBar1.FindItemByText("Button1");
                TextBox txtseach = (TextBox)textItem.FindControl("txtsearch");
                try
                {
                    if (sender.Equals(txtseach))
                    {
                        Bind_SearchBox(txtseach.Text);
                    }
                }
                catch (SqlException ex)
                {
                    lblMessage.Text = ex.Message;
                    Response.Redirect("View.aspx", false);
                }
            
        }
    and this method will call this

    Code:
     /// <summary>
        /// This Function will bind the ListBoxes on the Lefthand side of the Viewer
        /// It accept a search String
        /// </summary>
        public void Bind_SearchBox(String Search)
        {
            Session["Search"] = Search;
    
            RadPanelBar1.Items.Clear();
    
            RadScheduler1.Appointments.Clear();
            //get the Menu inside the toolbar

            ViewerService.extract extract = obj.getObjects(SessionKey, Search, Date1, false, Date2, false, "", "");

                    RadMenuItem childItem = new RadMenuItem(ParentRecordsRow[KK]);
                    //add the menu items
                    childItem.Text = ParentRecordsRow[KK];
                    //item.ImageUrl = "~/images/o!logo.png";
                    item.Items.Add(childItem);
    
    
                }
                 
            }
            catch (ApplicationException ex)
            {
                lblTestlabel.Text = ex.Message;
    
            }
            finally
            {
       
                obj.closeSession(SessionKey);
                obj = null;
                extract = null;
            }
     
    
        }

    and the page method for the client side

    Code:
       [WebMethod, System.Web.Script.Services.ScriptMethod]
        public static string Getadata(String StrSearch)
        {
            View obj = new View();
            obj.Bind_SearchBox(StrSearch);
            return StrSearch;
        }
    and on the client side

    Code:
      function keyPress_test() 
         {
          
            var tb = document.getElementById("<%=txtsearchid%>");
           
            if (window.event.keyCode == 13)
             {
                 PageMethods.Getadata(tb.value, myFunction(tb.Value));
                
                ToggleCollapsePane();
            }
            return false;
         }
     
     
        function myFunction(msg) {
            alert(msg);
        }

    So when i press enter it start searching and do all the data binding , now its fine but i went to debug it and i saw that this gets fired twice

    What is wrong ?

    Thanks
    Few companies that installed computers to reduce the employment of clerks have realized their expectations.... They now need more and more expensive clerks even though they call them "Developers" or "Programmers."

    Re: The function gets Fired Twice why ?

    If this is happening only when debugging, then you can use the stack trace.
    When entering the method the first and second time, check out the stack trace and you should see which functionality is calling your function.
