I use Login control to authenticate users and when users enter username and password web server contacts sql server to authenticate. Problem is that operation sometimes takes a few seconds, especially on first start. I want to user see message "logging in progress..." on that few seconds. I would normally use button.onclick client event to write message but it seems to Login control (with built-in button) does't have client events at all (!!). I tried to use server-side event "LoggingIn" but that event is unusable, I set sql server service offline and when click to "Log In" button, webserver is trying to connect about 10 seconds but server side-event "LoggingIn" not fired!
