Create an error window in web application with C#

[volpebianca]

Good evening,
i have a problem: i have created a little web application with some textbox. If user writes in these textbox i want that appears an error window. For example if there is a textbox which has to contain only positive integer and user writes "-1", i want that an error window appears. Into the window there is a label: "only positive integer", and a OK button, when user click button returns in the main webForm. How can i create this with Csharp?
Thank you very much.

since C#'s MessageBox would only run on the server you cannot use that (which, I don't think MessageBox.show is even valid in ASP.Net) the best shot you'd have would be making an html message box.

Good luck,
Kevin
