This is the complete code that i am testing and as mentioned in the subject line it does not work as expected
 
 
 
 
 
I just tested the VERY SAME code in an older project which is not a "Web Aplication" like this one.
Rather it's a website project and the code from above worked like a charm showing the messagebox. Not sure if it's your libraries or i miss something on my end?
Thank you
P.S. the problem is that when i click the Send button with all fields empty it cause postback instead to show the msgbox on client-side :(
