ria

I'm working on a Silverlight 4.0 application and am using RIA services. I have created a class on the server-side which has DataContract and DataMember attributes applied to it. A DomainService exposes this class as a query result and as such, generates code for it on the client. But somehow it doesn't generate code for all properties of the class. Primitive properties of type guid, string, int, bool etc are generated just fine, but if I have a property of my own complex type, that property isn't created on the client. Here's the class in question: [DataContract] [KnownType(typeof(SummaryGroup

I've been developing web apps for over a decade now, all the way from CGI to ASP.Net and Struts + Spring + Hibernate . The prevalent architectural style seems to be server-assisted MVC , e.g. Struts , Ruby on Rails , etc. Recent developments lead me to ask if these are on the decline. Adobe's AIR and Flex Microsoft's WPF and Silverlight Google's Chrome and Gears SOFEA and SOUI All of this leads me to believe that we're starting to come full-circle after a 15-year distraction kicked-off by the invention of the web. Over this period of time, we've been so fascinated by all the web has to offer

I am using RIA services. I need to select a parent entity ( UnitOccupier ) which has a number of related child entities( UnitOccupierDetails ). I need to filter the child entities to return a single record. How do I do this? var q = from uo in _unitOccupierContext.GetUnitOccupierQuery() where uo.UnitOccupierDetails.???? ---> I cant get to the child properties here Thanks You cannot include a filtered child collection of the selected parent. You can only include either the full collection or no child collection at all. But as a workaround you could use an intermediate anonymous type, like so:

I am using EF + RIA and unfortunately meet some problems with sorting by related entities. For such purpose there is ESQL query that I implemented (found only this solution): var queryESQL = string.Format( @" select VALUE ent from SomeEntities as ent join Attributes as ea ON ea.EntityId = ent.Id where ea.AttributeTypeId = @typeId order by ea.{0} {1}", columnName, descending ? "desc" : "asc"); var query = ObjectContext.CreateQuery<SomeEntity>(queryESQL, new ObjectParameter("typeId", attributeTypeId)); Tables have following structure: <Attribute>: int Id; decimal DecimalColumn; string

We have a requirement where we would like to redirect the user to a login page when ASP.NET Session expires and the user is working in a Silverlight plugin. So, scenario is, we have a legacy application which runs ASP.Net, all our new modules are in Silverlight, and the legacy app loads the Silverlight application. That all works :-) The user then walks away from their desk and comes back after the ASP.Net Session times out, but then tries to carry on doing something in the Silverlight App, which uses a RIA Domain Service. Because the session has time out, the RIA Domain Service fails, but it
