Use EntityManager.InvokeServerMethodAsync().

I exactly want to retreive from database, but not using default operations of entitymanager or using linq to devforce queries, but by calling some async server methods. How can i do it ?]]> Fri, 11 Jun 2010 22:25:42 -700 http://www.ideablade.com/forum/forum_posts.asp?TID=1864&PID=7297#7297 How add a custom method to entitymanager class ? : The EntityManager is operating... http://www.ideablade.com/forum/forum_posts.asp?TID=1864&PID=7260#7260 Author: GregD

The EntityManager is operating client-side. You can do all of the synchronous client-side stuff you want to. If you have to retrieve data from the backend database, that's a different story.]]> Thu, 10 Jun 2010 16:23:23 -700 http://www.ideablade.com/forum/forum_posts.asp?TID=1864&PID=7260#7260 How add a custom method to entitymanager class ? : Ishared my partial class as linked... http://www.ideablade.com/forum/forum_posts.asp?TID=1864&PID=7215#7215 Author: ehsan

I shared my partial class as linked file in client project & now I can call methods, but synchronously ! I've heared that silverlight does not supports synchronous calls, but I can call them synchronously !!!
Assume that my method does a time-consuming operation & returns a serializable data type, how can I define an asynchronous operation here ?

As I said before, you'll need to add the file with the partial EM class as a shared file in your client project in order to have access to the method - just as the TestTableModel.IB.Designer.cs file is linked as a shared file.

As for "calling it asynchronously": what exactly do you want this method to do and/or return?]]> Tue, 08 Jun 2010 17:41:22 -700 http://www.ideablade.com/forum/forum_posts.asp?TID=1864&PID=7210#7210 How add a custom method to entitymanager class ? : I've a file which has created... http://www.ideablade.com/forum/forum_posts.asp?TID=1864&PID=7195#7195 Author: ehsan

I've a file which has created by EntityFramework wizard & modified by devforce, it name is : TestTableModel.IB.Designer.cs
It contains :
 
...

namespace DevForceSilverlightApplication {

/// <summary>

/// The domain-specific EntityManager for your domain model.

/// </summary>

[IbEm.DataSourceKeyName(@"TestEntities")]

public partial class TestEntities : IbEm.EntityManager {

...
 
}
 
}
 
now I want to add some methods to TestEntities class (for example doTest method), I created a partical class in a new file & named id TestEntities.cs :
 

namespace DevForceSilverlightApplication {

public partial class TestEntities /*: IbEm.EntityManager*/{

   public void doTest() { ... }

}

}
 
I think this problem is a little more complicated than just adding a partial class & defining methods.
In wcf there is an [OperationContract] directive which identifies this method is a service operation, or in RIA there is an [EnableClientAcceess] directive which identifies client can see this class.
but here how can i access doTest method from client entitymanager object & call it asynchronously in silverlight ?

Did you define your partial class file in the web project and then forget to share it on the client? That would explain this:

I want to ad some custome methods to entity manager in my domain model . I need call those methods directly using silverlight, so they must be async .
how can i do this & where is the best place for defining such methods ? ( I tried to define them is a partial class but in this state I cant access them from client, when i define them in the main class, Client can see them, but when call them nothing happens. I know I should define them in a manner that I can call them asynchronously, but i dont know how :(( )
