Passing arguments from a button

I have a button like:  <asp:Button ID="Button2" runat="server" Text="Send" OnClick="Test"></asp:Button>
and want to send two arguments:  ddlArt.SelectedValue  and  ddlType.SelectedValue  by clicking the button to the function :
void Test(object sender, System.EventArgs e)  so the function ca update a sqlserver  with these arguments.
How shall I pass them from the button? I can not use the e argument
Hope someone can help me
