问题 It's incredible that such sample code doesn't even work. I have put this inside grid but I can't see any line (code taken from MSDN in fact): <Canvas Height="103" HorizontalAlignment="Left" Margin="30,166,0,0" Name="canvas1" VerticalAlignment="Top" Width="180"> <Line X1="0" Y1="10" X2="5" Y2="10" Stroke="Black" StrokeThickness="4" /> </Canvas> This is incredible that such simple thing like that would be so buggy so did I miss something see picture below ?

问题 Is it possible to get a reference to a Silverlight method purely by name from Javascript, and then invoke it? With pure Javascript objects you would be something like this: var f = theObj["theMethodName"]; f.call(theObj, "an arg"); But treating a Silverlight object as an associative array doesn't seem work. I'm guessing I could probably use Eval as a last resort, but I'd rather avoid it. 回答1: The question is on how to call a Silverlight function from Javascript by name. You can easily call

问题 I know this question has been asked before, but the other answers don't work for me because I'm on Windows Phone 7. I have a TextBlock whose Text is not known until runtime. I need to make all links clickable. My approach is basically the one described here, but there is no Hyperlink class in the WP7 SDK and I can't add a HyperlinkButton to textBlock.Inlines . Am I doing something wrong, or do I need a different approach? 回答1: WrapPanel with TextBlocks and HyperlinkButtons has been a pattern

问题 I would like to retrieve a list of links from SQLServer, and programmatically create some HyperlinkButtons from that list. These buttons should be added to a StackPnael. What is the best way to do this? Something along the lines of: private void RefreshMenu() { var dc = new FrameworkCMSDomainContext(); var query = dc.GetCMSPagesForSectionQuery(Section); dc.Load(query, (s) => { foreach(var page in dc.CMSPages) { HyperlinkButton btn = new HyperlinkButton(); btn.NavigateUri = new Uri("/" +

问题 I am new to Prism and I am trying to determine a best practice for deactivating a view in a Prism 2 application -- when a user clicks a button on the view I want to deactivate the view. The view is executing a command when the button is clicked. The view model is receiving the command but the viewmodel does not have a reference to the regionmanager.
