Remote File Data Access - Event Not Fired On Button Click

I am writing a program to access the remote file data using FTP on button click event. Set breakpoint in the fist line of button click event. That program is using windows application vb.net 2008. If I run the application, when I click the button, it does not fire a click event of the button.

Here's my code:
Dim reqFTP As FtpWebRequest
Dim filepath As String
Dim filename As String
Dim filename1 As String
Dim ftpserverip As String
[Code] .....
During run time when I click the button the control not entered to an click event.
