问题 I am creating one installer which needs to change config file of my one silverlight component. This component's config file is inside XAP file. Is there any way to change that config file? 回答1: Host your configuration file side-by-side with your XAP file. ../YourProject.XAP ../YourProjectSettings.XML The following code will download a file called "Settings.xml" which sits in the same directory as your XAP, and place it in Isolated Storage. You can then open/close/parse it as needed later.

阅读更多关于 Filling Grid with TextBoxes programmatically in WPF

问题 Let's assume that I have defined two Grid s and few TextBox es in my XAML . I want to put these TextBox es in the Grid s at runtime (I know which TextBox should be put in which Grid after starting the application). I thought it would be possible to simply add a row definition to the Grid in my C# code, however the text boxes bind to some Style . Maybe there is a simple solution (entirely in XAML - preferred)? So the question is - how to dynamically fill the grid during the runtime with the

问题 I am looking at this, Clear Binding in Silverlight (Remove Data Binding from SetBinding) But to clear bindings you have to specify a dependency property. Is there a way to generically find all the bindings on a DependencyObject and clear them?

1.核心命名空间 1.xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"是silverlight的核心命名空间，包含所有了的silverlight的核心类。比如usercontrol和grid等.通常此命名空间声明时没有加前缀，因此它成为了整个文档的的默认命名空间。换句话说就是页面所有的元素都默认的属于此命名空间，除非声明了其它的。 2.xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" 表示XAML的命名空间。此命名空间的前缀为x。你可以通过把命名空间放在一个XML元素名称或属性前使用它(例如：x:Class="CheckNamespace.MainPage" 核心命名空间主要是让XAML解析器找到正确的类。比如，当遇到Grid和UserControl时，解析器发现它在 http://schemas.microsoft.com/winfx/2006/xaml/presentation 命名空间下。然后继续寻找相对应的SilverLight对应的类，直到找到匹配的类system.Windows.Usercontrol和System.Windows.Controls.Grid为止。 2.设计命名空间
