I noticed a few tweets this morning about a new version of Silverlight having been released - Silverlight 2 GDR 1 (2.0.40115.0). Details of what/why/should I target it/is it backward compatible/etc seem incredibly thin on the ground. Hitting this Silverlight page on Microsoft.com tells me my version (RTW) is now out of date and I shoul...

Hi, I've made a simple storyboard that takes a particular ListBoxItem and lets it grow by a factor of 1.3. I'd like to add this animation to every ListBoxItem I create dynamically so that it can be activated when it gets a mouse-over, but the storyboard seems to be hardcoded to that first item: <Storyboard x:Name="ListItem_MouseEntered...
I have a simple Grid control in my silverlight page. One of the cells in the grid is supposed to house a web page. As there is no web browser control, I have added an IFRAME to the HTML page and I modify the size and position of the IFRAME after loading so it looks like it is in the grid cell. I also have a GridSplitter that I use to al...

Is anyone using the SLExtensions command pattern (http://www.codeplex.com/SLExtensions) for associating commands to Silverlight control events? From what I've seen, you can only attach a command for one event per control. For example, you can only add a click event for a button, a keydown event for a textbox, etc. What if I wanted to a...
I make calls to a WCF service from my silverlight application. I am doing this asynchronously and I am not blocking execution after making the async. call (that means, I am not using wait-join mechanism frm this page). I do not want the flow to get blocked. However, I would like to detect that the WCF call has gone into a wait state so ...
If you read the release notes from the Feb 18th release of Silverlight, you will see a line that states: graceful failures when attempting to use features that require .Net Framework 3.0 or 3.5 on machines that do not have either framework installed What does this mean? Surely Silverlight has no direct dependencies to the full .Net 3....
I'm programmatically adding a UserControl to another in Silverlight 2 by adding it to the parent control's "Children" collection. At first this works fine. If I do something else to the window (in my case I'm scrolling the entire panel out of view then back into view) then it apparently changes the render order and causes my control to ...

Ok, I have a pretty complex silverlight app that gets its data from a WCF service (asp.net hosted service layer) which in turn calls into a data layer that calls stored procedures in a SQL 2005 DB to extract the needed data. So the round trip goes like this: Silverlight App --> WCF Service --> Data Layer --> DB --> Data Layer --> WCF S...

Now I am trying figure out how to implement drag and drop with NESTED lists. For instance I have a listview containing projects and each project item contains another listview of tasks. I ...

Does anyone know of a simple WPF or Silverlight framework which enables you to e.g. define some database tables in e.g. SQL Server compact database and then the framework automatically creates the Window classes etc. which allows a user to login and edit that data?

Hi, I'm making a silverlight app that when the user does a mouse-over some tab bars, he/she will see a preview of the page it will link to.
