VB has a function InputBox() that will prompt the user to enter a single value, then click OK.
Is there a parallel functionality in ASP.NET, that will get the browser to pop up some kind of input box to return a single value?
If not, how do you recommend I achieve this effect?
You can do this in JavaScript
But most web apps seem to use of screen forms and simulated modal dialogs (fade and disable rest of screen)
jQuery is your friend for this, try simplemodal
