AddNewCore to Async call EC Child

lds posted on Friday, August 28, 2009

I'm having hard time figuring out how to code the ECL AddNewCore method in Silverlight to Asynchronously call the EC Child_Create on the server side so that I can initialize some properties with data from the database.

I have the following but the EC Child_Create does not get called.

   ECL - Silverlight (.Client)
   protected override void AddNewCore()
   {
      var child = DataPortal.CreateChild<EmployeeType>();
      Add(child);
   }

   EC - .Net (.Server)
   protected override void Child_Create()
   {
      // Initialize some Properties with values from Database;
   }

Can anyone shed some light on the subject?

Thanks

It Silverlight it should be possible, but in WPF it isn't possible to implement Async behavior in the AddNewCode()

I didn't try to figure it out in Silverlight, so i don't know how it should be done. If u fixed your problem i would like to hear the solution for it.

It is possible to do in Silverlight

ECL:

Protected override AddNewCore()
{
EC.NewEC((o,e)=>
{
If (e.Error == null)
{
Add(e.NewObject;
OnAddedNew(e.NewObject)
}
Else
{
//Do your error handling here
}
}
}

EC

Internal void NewEC(EventHandler> completed)
{
DataPortal dp = new DataPortal;
dp.CreateCompleted = completed;
dp.BeginCreate();
}

In ECL you could use a spate event handler instead of lambda expression if you would like

Thanks Sergeyb that helped a lot...
I'm wondering if you could answer one more:

If the EC: DataPortal_Create() is used instead of Child_Create() what MarkX() should be used beside MarkAsChild()?
