I couldn't get this to work in Silverlight, so I created two test projects. One simple WPF project and one simple Silverlight project that both do only one thing: set a public static readonly variable in code, and use it in a completely bare bones XAML. In WPF, works without a hitch. In Silverlight, I get the following compiler warni...
I am creating a Silverlight 2 user interface to a remote instrument. There are two concurrent users at different sites interacting with the instrument (operator at the instrument and remote scientist) and any number of observer users not interacting with it, just watching. However, whenever one of the two active users changes something t...
There are lots of great examples around on MVVM but I'm still confused. Lets say you have a CustomerModel and a CustomerViewModel. It seems there would be a Name property on the CustomerModel and one on the CustomerViewModel. The setter on the CustomerViewModel will set the CustomerModel Name property and then call the OnPropertyChange...
So lets say i have an OrderModel and an OrderViewModel. I have the Supplier, Order Date, etc properties on both the ViewModel and the Model and they are linked up. Seen examples on this and seems straighforward enough, although somewhat duplicated in terms of writing setters/getters. Now what do I do with the OrderDetails? In my model I...
What are some tools/practices used to measure performance with Silverlight? I am interested in the performance costs of rendering certain xaml objects as well as algorithms I have written. I was about to start writing my own classes for this, but I thought I would ask here first. Thank you in advance. ...
I have found that datagrid columns can be dynamically created and bound in Silverlight. However I can't find a way to bind data to those columns. If I try to bind any type of object with AutoGenerateColumns = true, then the names of each property of the object get added as columns and the object information is displayed in the grid in a...

In ASP.NET, one finds themselves often writing code like: foreach(DataListItem item in theDataList.Items){ MyUserControl foo = item.FindControl("myUserControl") as MyUserControl; foo.DoSomethingNice(); } In Silverlight, how can one iterate through the constituent controls of a DataGrid (or other collection bound control)? I w...
I am pretty new to Silverlight and just now realised that there is a passwordbox control in Silverlight 2. But there are not much articles about how to get the value from this control.

Has anyone developed or know of a place where I could find a Silverlight implementation of NetDataContractSerializer? This WCF and Silverlight Comparison states that Silverlight does not ship with an implementation of NetDataContractSerializer. I'm hoping to avoid developing one myself. Thanks! ...
Is there a way to hook into how specific types are serialized when using WCF and Silverlight. For example, I need to tweak how System.DateTime properties are serialized/deserialized. ...
I'm wondering what strategies exist to handle object integrity in a stateful client like a Flex or Silverlight app. What I mean is the following: consider an application where you have a Group and a Member entity. Groups contain multiple members and members can belong to multiple groups. A view lists the different groups, which are laz...
In my Silverlight project, I would like to make an assembly which contains .xaml that can't be seen from outside of the assembly. However, there is no clear way I can do this. When I modify the access modifier on the .xaml.cs file, the compiler tells me: Partial declarations of "My xaml class here" have conflicting accessibility modifie...
Hi! Sometimes I need to call WCF service in Silverlight and block UI until it returns. Sure I can do it in three steps: Setup handlers and block UI Call service Unblock UI when everything is done. However, I'd like to add DoSomethingSync method to service client class and just call it whenever I need. Is it possible? Has anyone re...
I'm having a right barney getting my head around how everything fits together using the MVVM pattern. It all seems quite simple in practice but trying to implement it I seem to be breaking various other rules that I try to code by. Just as a side note, I'm trying to implement the pattern using Flex, not Silverlight or WPF, so if anyone...

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 ...
