问题 How can I add tabs to a tabcontrol that exists in one usercontrol from another usercontrol that is contained within a tab itself?? Can I do it without passing in the tabcontrol as a parameter in the constructor, perhaps via some static global method? I've tried public static ObservableTabCollection FindCollectionFromUC(this DependencyObject depObject) { bool loop = true; var parent = (VisualTreeHelper.GetParent(depObject) as FrameworkElement); while (loop) { if (parent.GetType() is typeof

问题 I recently decided to go into WP7 app development, but haven't actually started learning silverlight/xna; Only C#. I already know C++ quite well. my Dad, who works for Microsoft, has recently told me that there's no point to learning Silverlight because it will become irrelevant in the long run; due to HTML5's superiority. However, Im not aware of any way to develop apps for WP7 using HTML5, and I barely know anything about markup languagez anyway. I wanted to get some proffesional advice on

问题 Is there comprehensive list of what's new in silverlight 5? I'm seeing different blogs, etc but obviously the devil is in details.

问题 I've added a domain service class to the server side project of my SL4 / EF / RIA Services application. I've managed to create all the necessary elements needed in my web.config section. (Btw, why isn't this generated for me when I created my Domain Service Class?) What I'm missing now is what to put in the contract attribute of my endpoint element: <service behaviorConfiguration="XXX.Web.RIAServices.MyServiceBehavior" name="XXX.Web.RIAServices.MyService"> <endpoint address="http://localhost

问题 I have a feeling i'm missing something obvious here, but i can not find a way to iterate through a DataGrids DataGridRow collection. I have a grid which has an itemssource of a collection of my class set. I am trying to iterate through the rows and highlight any rows that meet a certain condition but can't for the life of me see how. 回答1: You don't want to iterate through the grid. That's old-skool WinForms thinking. The Grids in WPF and Silverlight have been redesigned with MVVM in mind;

问题 I have a large Silverlight application, and we have decided to redesign the whole interface. Since it is a good time to polish some issues, I would like to read some XAML good practices to take into account when designing. Does anyone know of a good Silverlight (or even WPF) book or guide to read about XAML? I'm not looking for a tutorial on XAML, I just want to know some good practices. Thanks! 回答1: This is a good link having video interview with people who have worked with wpf and

问题 The task: Make the text content of the InlineUIContainer to be inline with the outer text. The standard behaviour of the InlineUIContainer content is when the bottom edge is inline with the outer text. It is possible to shift the position of InlineUIContainer with RenderTransform, but the value of Y has to be chosen for each font type and size - not a perfect way. <RichTextBox> <Paragraph> LLL <InlineUIContainer> <Border Background="LightGoldenrodYellow"> <TextBlock Text="LLL"/> </Border> <

问题 Update : This is a confirmed bug in Silverlight 4 beta. http://connect.microsoft.com/VisualStudio/feedback/ViewFeedback.aspx?FeedbackID=523052 I solved this issue by switching to a full blown WPF application and using regular old Microsoft.Office.Interop.Word. But I'm still very interested in how to get this to work using the dynamic values from ComAutomationFactory. This may be more of a C# 4.0 question, but what I'm trying to do is leverage the ComAutomationFactory class in a trusted SL4
