با این که برنامه به راحتی اجرا میشود و خروجی آن قابل مشاهده است ولی امکان نمایش فرم در حالت design وجود ندارد. متاسفانه در Windows Appها برای تعریف فرم‌ها به صورت generic یا این مشکل روبرور هستیم. تنها راه موجود برای حل این مشکل استفاده از یک کلاس کمکی است. به صورت زیر:
public partial class FrmTest : FrmTestHelp
{
public FrmTest()
{
InitializeComponent();
}
}
public class FrmTestHelp : FrmBase<String>
{
}public class WindowBase<T> : Window where T : class
{
}public partial class MainWindow: WindowBase<String>
{
public MainWindow()
{
InitializeComponent();
}
}<local:WindowBase x:Class="GenericWindows.MainWindow"
x:TypeArguments="sys:String" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:local="clr-namespace:GenericWindows" xmlns:sys="clr-namespace:System;assembly=mscorlib" Title="MainWindow" Height="350" Width="525"> <Grid> </Grid> </local:WindowBase>
<div class="alert">
نمایش اعلانات
</div> 
تعدادی کلاس دیگر نیز جهت استفاده از رنگ‌های مختلف نیز توسط بوت استرپ ارائه شده است:
همچنین اگر مایل بودید میتوانید با افزودن یک دکمه با کلاس close و ویژگی data-dismiss مساوی alert، امکان بستن پیام را در اختیار کاربر قرار دهید:
<div class="alert alert-warning alert-dismissable"> <button type="button" class="close" data-dismiss="alert" aria-hidden="true">×</button> نمایش اعلان </div>
در ادامه قصد داریم این پیام را بعد از ثبت اطلاعات، به کاربر نمایش دهیم. یعنی در داخل کد، امکان صدا زدن این نوع پیام‌ها را داشته باشیم.
ابتدا کلاس‌های زیر را تعریف میکنیم:
کلاس Alert
public class Alert
{
public const string TempDataKey = "TempDataAlerts";
public string AlertStyle { get; set; }
public string Message { get; set; }
public bool Dismissable { get; set; }
} در کلاس فوق خصوصیت یک alert را تعریف کرده‌ایم (از خاصیت TempDataKey جهت پاس دادن alertها به view استفاده میکنیم).
public class AlertStyles
{
public const string Success = "success";
public const string Information = "info";
public const string Warning = "warning";
public const string Danger = "danger";
} public class BaseController : Controller
{
public void Success(string message, bool dismissable = false)
{
AddAlert(AlertStyles.Success, message, dismissable);
}
public void Information(string message, bool dismissable = false)
{
AddAlert(AlertStyles.Information, message, dismissable);
}
public void Warning(string message, bool dismissable = false)
{
AddAlert(AlertStyles.Warning, message, dismissable);
}
public void Danger(string message, bool dismissable = false)
{
AddAlert(AlertStyles.Danger, message, dismissable);
}
private void AddAlert(string alertStyle, string message, bool dismissable)
{
var alerts = TempData.ContainsKey(Alert.TempDataKey)
? (List<Alert>)TempData[Alert.TempDataKey]

alerts.Add(new Alert
{
AlertStyle = alertStyle,
Message = message,
Dismissable = dismissable
});
TempData[Alert.TempDataKey] = alerts;
