Is it possible to insert a TextBox for the user to input text on top of a MessageBox in Windows Phone 7?
Thanks.
No - it isn't
But the "Input Prompt" in http://coding4fun.codeplex.com/ might help you. See the overview at http://www.windowsphonegeek.com/articles/Coding4Fun-Toolkit-for-WP7-Overview-and-Getting-Started
