Message box cant be displayed When run in IIS?

I wants to display an OK/CANCEL message box. I have written like this. 

   if (MessageBox.Show("Are you sure you wants to Save the details ?  ", "Validate", MessageBoxButtons.OKCancel) == DialogResult.OK)
    {
         // do something if "OK "
    }

it works locally well.. but on IIS shows an error " Showing a modal dialog box or form when the application is not running in UserInteractive mode is not a valid operation. Specify the ServiceNotification or DefaultDesktopOnly style to display a notification from a service application." please help.

To get the effect I believe you are wanting, you'll want to use the Javascript confirm() function. It is typically used like this: 

<asp:Button runat="server" OnClientClick="return confirm('Are you sure you want to save the details?')" id="btnSubmit" OnClick="btnSubmit_Click" />

This would, upon clicking the button, display a confirmation box that would stop the server OnClick event from firing if the user clicks No, Cancel, etc.

OnClientClick will render as an onclick event on the <input> tag. The rest is determined by the browser's handling of Javascript. See What's the effect of adding 'return false' to a click event listener? for more details on what the return value of the code in OnClick (OnClientClick) does.

Here's an example of the return values of confirm() using Chrome. For the first execution I had clicked Cancel.
