Is there a way to know what parameters are needed by an event in Visual Studio 2010?

Let's say I have a DropDownList control and I want to bind a method to the "OnSelectedIndexChanged", I would do something like this

In the ASPX File:

<asp:DropDownList ID="lstMyList" runat="server" OnSelectedIndexChanged="lstMyList_SelectedIndexChanged"></asp:DropDownList>

In the codebehind:

protected void lstMyList_SelectedIndexChanged(object sender, EventArgs e) 
{
    ...
}

Is there a way to know what parameters the method needs? (In this case, an object for the sender and an EventArgs parameter for the event.)

I know you can easily create the method by double-clicking the right event in Design Mode, but it does a mess with your code so I prefer not to use it.

Thanks!
