event Page\_Error(object sender, EventArgs e) doesn't handle expection. Exception is handling by Visual Studio.

I tried throw Exception by Page\_Load or button but still isn't working. I can't search any information about this problem. In my book is show simple example with Page\_Load, Page\_Error, Button and according my book this should working. I guess that in Web.config is missing something.

```
    void Page_Error(object sender, EventArgs e)
    {
        Response.Clear();
        Exception ex = Server.GetLastError();
        Response.Write("Something not yet");
        Response.Write(ex.Message);
        Server.ClearError();
    }

protected void Page_Load(object sender, EventArgs e)
    {
        Response.Write("Load event fired");
        throw new Exception();
    }

```

I expect that throwed Exception will be handled by Page\_Error, not by Visual Studio.
