Silverlight：多次引用同一元素而没有冗余？

发布于 2024-10-01 15:37:27 字数 665 浏览 5 评论 0原文

我正在构建一个 Silverlight Windows Phone 7 应用程序。我有以下元素：

<TextBox x:Name="DownloadFailed"
         Text="MySite.com could not be reached at this time. Do you have a network connection? &#xd;&#xa;&#xd;&#xa;Try again in a few minutes." 
         BorderBrush="{x:Null}" Background="{x:Null}" 
         Foreground="{StaticResource PhoneDisabledBrush}" Margin="56,8,8,-8" TextWrapping="Wrap" />

如何定义一次并将其添加到我的应用程序中的多个页面？

我可以创建一个用户控件，但这对于这样一个具有一些属性的单个元素来说似乎有点矫枉过正。

我可以以某种方式使用 StaticResource 字典吗？还是只是为了属性？

我这样做的原因是因为我在许多不同的页面上都有内容，应用程序尝试从网络服务加载这些内容，但可能会失败。对于这样的控件/内容是否有常规的设计模式/封装？

I'm building a Silverlight Windows Phone 7 app. I have the following element:

<TextBox x:Name="DownloadFailed"
         Text="MySite.com could not be reached at this time. Do you have a network connection? 

Try again in a few minutes." 
         BorderBrush="{x:Null}" Background="{x:Null}" 
         Foreground="{StaticResource PhoneDisabledBrush}" Margin="56,8,8,-8" TextWrapping="Wrap" />

How can I define this once and add it to multiple pages in my app?

I could make a user control, but that seems like overkill for such a single element with a few properties.

Could I use the StaticResource dictionary somehow? Or is that just for properties?

The reason I'm doing this is because I have content on a number of different pages that the app attempts to load from a web service, but may fail. Is there a conventional design pattern / encapsulation for such a control/content?

定义它

public static void ShowMessage(string message)
{
    Deployment.Current.Dispatcher.BeginInvoke(() => MessageBox.Show(message));
}

我在我的应用程序中实现此要求的一种方法是在静态 Helper 类中。然后我将其用作 -

Helper.ShowMessage("Error Loading Data from remote service. Please try again later.");

您可以考虑构建一个包装 TextBlock 的控件（您的示例代码使用 TextBox，要显示静态文本，您可以使用 TextBlock< /code>) 并使用上述方法调用控件。

One way I have implemented this requirement in my apps to define this -

public static void ShowMessage(string message)
{
    Deployment.Current.Dispatcher.BeginInvoke(() => MessageBox.Show(message));
}

in a static Helper class. I then use it as -

Helper.ShowMessage("Error Loading Data from remote service. Please try again later.");

You may consider building a control that wraps the TextBlock (Your sample code uses TextBox, to display static text, you can use TextBlock) and invoke the control using the method above.
