/// A JavaScript alert 
/// </summary>
public static class Alert
    /// <summary>
    /// Shows a client-side JavaScript alert in the browser.

    /// <param name="message">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("<script type=\"text/javascript\">$(document).ready(function(){alert('{0}');});</script>", 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 all ready on the Page

        if (page != null && !page.ClientScript.IsClientScriptBlockRegistered("alert"))


            page.ClientScript.RegisterClientScriptBlock(typeof(Alert), "alert", script);
