Silverlight: How to create a page dynamically

阅读更多关于 Silverlight: How to create a page dynamically

问题 Problem: I store the page name I want opened in Silverlight in a database. When I startup the application I want to set the page to this string so rather than this: this.RootVisual = new MainPage(); I want something like this string pageName = getValueFromDatabase() if (!PageExists(pageName)) throw error else this.RootVisual = SomeWizzyMethodToCreatePage(pageName) I guess I will need to use reflection here to find all of the pages (PageExists), and then somehow create a new instance

Click-to-edit in Silverlight

阅读更多关于 Click-to-edit in Silverlight

问题 Is there a way to make a "click-to-edit" control in silverlight? I've got some items that will be displayed in a treeview control, and I would like the labels to be editable directly in the treeview. Anyone know how to do this? 回答1: Very easy actually. I have implemented many forms with such a swapping mechanism. You could do this using a Converter and do a simple BooleanToVisibility conversion on an IsEditable property that exists on the entities that you bind to your TreeView. Within your

问题 Our company is trying to remove Visual Studio 2015 all together but we still have some Silverlight code. Is there a workaround for being able to work with Silverlight in VS 2017 even though it's not supported, or a more light-weight solution rather than having to keep either both IDE's or just use 2015? 回答1: I'm left using both IDEs as 2017 does not support it. The solution uses 2017 but if I have to edit SL code I have to go back to the previous IDE version. To quote Visual Studio 2017

问题 I'm currently writing an eBook reader for Windows Phone Seven, and I'm trying to style it like the Kindle reader. In order to do so, I need to split my books up into pages, and this is going to get a lot more complex when variable font sizes are added. To do this at the moment, I just add a word at a time into the textblock until it becomes higher than its container. As you can imagine though, with a document of over 120,000 words, this takes an unacceptable period of time. Is there a way I

【原】用Blend 3/SketchFlow画Silverlight 3原型图

简介：之前做Silverlight项目，用过Axure RP画原型图，虽然也是很好的工具，但人家本职毕竟是用来画网页原型的，和Silverlight总有些隔膜：控件上有欠缺；不提供样例数据生成；一些较复杂的页面不支持手绘，只能截图；状态、动画统统没有……于是Sketch Flow一出，立刻下手研究，最终感受是：到底是一个系统的，用起来舒服多了。创建Sketch Flow项目 Blend 3里新新添加两种项目模板，分别是Silverlight 3和WPF的SketchFlow Application。创建Silverlight 3 SkethcFlow Application，会发现同时创建了两个Project。与在VS中创建Silverlight工程时会创建一个“Silverlight应用程序”项目和一个“网站应用程序”项目不同，这里除了创建一个“Silverlight应用程序”项目，还创建了一个“Silverlight库”项目，而大部分画原型图的过程就是充实这个Silverlight库项目的过程。研究这个项目，发现下面有一个文件夹放了三种特殊的字体，另有一个声明样式的XAML文件，另有一个名为Sketch.Flow的文件，里面会有一些原型图的配置信息。理论上这三部分都是可以增删改的。但这里我们只把关注点放到默认选中的Screen 1.xaml这个文件上。关于Screen
