silverlight

问题 From what I can find, seems like the IsolatedStorage supposed to be permanent unless the user delete it manually. And the following thread says so too: Is Silverlight isolated storage treated as permanent, or as a cache? However seems like if I shut down my application and restart it (as I am debugging on debug mode - not sure if that makes a different), the data I stored earlier is gone. For example, just as pseudocode: onClick = let storage = IsolatedStorageSettings.ApplicationSettings let

问题 I am using a C1ReportViewer control, and have already posted a question on the C1 forums, however i thought i would post here as well to see if anyone had run across a similar issue. The control uses the generic silverlight PrintDocument() method. When printing a Crystal Report from this control in Silverlight 5 sometimes the report prints out garbled, meaning different sized text, tapered lines and generally out of position. It also rarely prints the entire report. I have narrowed the issue

问题 **This is for silverlight application. I have a stream with xml data, which after loading massage the data and generate final file. I start by load using XDocument.Load(stream).

问题 We're trying to learn to use T4 Templates. I have a desire to use the System.Data.Entity.Design.PluralizationServices library in order to better pluralize some Entity Model names within my template, but I've come across some issues in the achievement of this goal. Running code to generate output text. I think this is possible, but if it's not going to work, then there's no need to go any further. (I could call Date.Now.ToString() and get the expected result.

问题 I have a collection of buttons in a grid. For each one of these buttons, I want to handle the MouseEnter and MouseLeave events to animate the height of the button (and do some other interesting stuff). It all works good until I start moving my mouse too fast over and off the buttons which eventually cause the events to take place at before the other is complete. What's the best way of making sure the events wait for eachother before being triggered? UPDATE: Going by x0r's advice, I refactored

问题 I have a ListBox in a grid that gets databound when the page loads... pretty straightforward. The problem I'm having is that, after the box is databound, I can scroll... but not all the way to the bottom of the list. It stops an item or two short and won't let me scroll anymore.
