I am using a aspx page which is having a button.

 <asp:Button ID=savebtn runat=server OnClick=savebtn_Click Style=display: none />

There are two ways to cause post back as shown in the below code.

 $(document).ready(function () {

               var id = document.getElementById('<%= savebtn.ClientID %>');

       //Cause post back & calls page load but not savebtn_Click event

            __doPostBack('<%= savebtn.ClientID  %>', 'OnClick');



    });



    $(document).ready(function () {

                     var id = document.getElementById('<%= savebtn.ClientID %>');

           //Cuase postback & calls both PageLoad and savebtn_Click events.

           //If I use method, There is no way to know which control caused postback

            id.click();



    });

When I use __doPostBack, It calls page load event but not btn click event.

Is there any way using __doPostBack to trigger Page Load as well as savebtn_Click event.

If I use id.click(); as shown above, I am able to call savebtn_Click but it does not tells me which control caused the post back.
