You are attempting to use a MessageBox intended for Windows Forms applications, not for Web applications. The interfaces for the two platforms are entirely different.

You can't use Winforms.MessageBox directly in a web app. There are, however, *several* approaches available for *simulating* a Message Box in a web application. You can call a javascript alert; you can even hide a
within your web page and programmatically style/show it when necessary. There are *many* options available.

The Message box control you were using is for windows desktop application, in another word, it runs under interactive mode which means the dialog only pops up on the machine the code runs on, so in your case, if you look at your server which hosts your web application, you could see it pops up there.

So basically you would need to use web based dialog box, you could try Jquery dialog, it is very easy to use, look at here for the demo and code example.

Please mark it as answer if it solves your problem.

i want to make an ok and cancel and i dont think this is availble in Javascript – KAS Jun 04 '15 at 19:40
javascript could do window.confirm("text"), it would show ok and cancel. Also if you use Jquery Dialog, you could customize it completely by putting any buttons you want. – Kane Wang Jun 04 '15 at 20:18
