Simple, Add the following class in your solution/project, /// /// A JavaScript alert /// public static class Alert { /// /// Shows a client-side JavaScript alert in the browser. /// /// The message to appear in the alert. public static void Show(string message) { // Cleans the message to allow single quotation marks string cleanMessage = message.Replace("'", "\'"); string script = string.Format(" $(document).ready(function(){alert('{0}');}); ", cleanMessage); // Gets the executing web page Page page = HttpContext.Current.CurrentHandler as Page; // Checks if the handler is a Page and that the script isn't allready on the Page if (page != null && !page.ClientScript.IsClientScriptBlockRegistered("alert")) { page.ClientScript.RegisterClientScriptBlock(typeof(Alert), "alert", script); } } } Just use Alert.Show("Your message"); where ever you want to show the message.
