I just got the same trouble, have to do some logic judgement in the Page_Load method to treat different event(which button was clicked). I realize the arm to get the as the following example. The front end aspx source code(I have many Buttons with IDs F2, F3, F6, F12.

The back end aspx.cs source code, what I need to do is judge which button was clicked when Page_Load was triggered. It seems a little stupid, but works. In your situation, the button be clicked will be added into dic. I hope that will be helpful to some one.

Dictionary dic = new Dictionary();
foreach(var id in new string[]{"F2","F3","F6","F12"})
{
       foreach (var key in Request.Params.AllKeys)
                    {
                        if (key != null && key.ToString().Contains(id))
                            dic.Add(id, Request[key.ToString()].ToString()); 
                    }
}
