I need to display a YesNo messagebox, in case of a server side code execution failure. As far as I can tell, you can't show a messagebox from the server side. Is a walk around of sorts, where I fire a hidden button's OnClientClick Event programmatically in order to display a messagebox is possible? If so, how do I trigger it? If not, Is there any other way to display a YesNo messagebox from the server side?
As far as I can tell, unless I misunderstood, the solutions I was given or was refered to, handled cases where client side script fires the second button's event, but that's not what I'm looking for. I need the server side script to trigger the client side script/event.
