0	You can use the PageMethods to call server side function (C#) from ClientSide(Javascript) Please try the below implementation 1) Add a script Manager to your page and set the 'EnablePageMethods' property of script manager to True. <asp:ScriptManager ID="ScriptManager2" runat="server" EnablePageMethods="true"/> 2) Add Javascript function to the body section of page <body> <form id="form1" runat="server"> <script type="text/javascript"> function CallingServerSideFunction() { PageMethods.Add(1,2); } </script> </form> </body> 3) Change you method like given below //Please note that the method should be a Static and WebMethod. [System.Web.Services.WebMethod] public static void Add(int x, int y) { int k = x + y; //Your Logic comes here } 4) Calling the Javascript function <input id="Button2" type="button" value="FunctionCall" onclick="CallingServerSideFunction()" /> Thanks, A2H My Blog Only4ram, if this helps please login to Mark As Answer. \| Alert Moderator

You can use the PageMethods to call server side function (C#) from ClientSide(Javascript)

Please try the below implementation

1) Add a script Manager to your page and set the 'EnablePageMethods' property of script manager to True.

<asp:ScriptManager ID="ScriptManager2" runat="server" EnablePageMethods="true"/>

2) Add Javascript function to the body section of page

<body>

    <form id="form1" runat="server">

    <script type="text/javascript">

        function CallingServerSideFunction() {

            PageMethods.Add(1,2);

        }

    </script>

    </form>

</body>

3) Change you method like given below

  //Please note that the method should be a Static and WebMethod.

        [System.Web.Services.WebMethod]

        public static void Add(int x, int y)

        {

            int k = x + y;



            //Your Logic comes here

        }

4) Calling the Javascript function

<input id="Button2" type="button" value="FunctionCall" onclick="CallingServerSideFunction()" />

Thanks,
