I have a small SL application that uses RIA services to display employee data (Northwind database) in a data grid. I have a text filter, that works fine against varchar columns but does not filter against a nullable int column. Here is the xaml: <UserControl xmlns:riaControls="clr-namespace:System.Windows.Controls;assembly=System.Window...
Hi all, I've just been toying around with the new WCF RIA Services Beta for Silverlight this evening. So far it looks nice, but I've come across a few barriers when trying to retrieve data and exposing it to the UI via binding. First of all, how am I able to get a single integer or string value from my service? Say if I have this metho...
I have a very simple sample silverlight application. I added a domain service to it with an entity model that has one entity. The client app simply loads all rows in the entity at startup. When I run this on my development box, it works as expected. However, when I move it to our test server I get an exception saying that the method I am...
When I was developing web-apps with jsp/jstl and jQuery, I used to write nice html-code, separated from styles and scripts. JSP inserted some odd spaces and blank lines but nothing else. Now I'm trying to develop with jsf. JSF has lots of libs for creating RIA with numerous components so it should be much faster to develop web-apps wi...
Hi all, A quick question here about the new WCF Ria services beta: If I do this in code-behind: EntitySet e = MyContext.Employees It seems that the entityset is always empty at runtime? I.e. if I want to loop through the Employee entityset. Also, if I'm getting the Enumerator for the entityset, I'll get an error telling me that the...
I know I've had this problem when I started working with Silverlight, but I can't for the life of me remember how to fix it.

Now I pull open the Web properties and change the web proj...

As a familiar example let's call it aspnet_User which has a member object called aspnet_Membership; aspnet_User has a member called "UserName" and aspnet_Membership has a member called "Email". Now using the aspnet_User as a datacontext I want to bind to any changes in...

One of the columns is called OrdinalPosition and I have specified that the grid is to sort by this column. I have a custom column with up and down ar...
It seems the world is awash with people having problems deploying RIA WCF services, and now I'm one too. I've already tried a bunch of things, but to no avail. I need WCF RIA to support a Silverlight 3 application I've built. The short story is, using the new WCF RIA services (Nov 09?) I open VS 2008, create new project (silverlight a...
