You are trying to use a WinForms specific command (msgbox) in an asp.net environment, which is not allowed (this is exactly what the error also says)

if you want a message box to appear at client side, you should use javascript to show the message. You could do something like response.write("<script type='text/javascript'>a l e r t('Your repair id is: " + id.tostring + "') </script>")

Remove extra spaces in a l e r t (put there to prevent js filtering)

I don't understand what you are saying here.

the bottom line is: you are not coding for winforms, but for asp.net. The msgbox command is not allowed in asp.net.

You can use inline messages like this: response.write("mymessage"), you can use a label on the control, and set that label to a value, you can open a javascript alert on your page, and there a lot of other ways to do what you want. You might want to get a basic book on asp.net, to figure out the basics.. (your question is not really dotnetnuke specific)
