Webservices and ChangeSets

[Nigel]

Hi I am a little confused, Looking at the examples (and the auto generated asmx file) the webservice returns ChangeSet objects, whihc looks great as just sending it back will make the changes that occured at the top tier of the solution. However I can not work how to use this class, and the API is not very descriptive.

The web method simply returns a changeset

[

WebMethod] 
public Telerik.OpenAccess.ObjectContainer.ChangeSet GetDocumentTree()
{

 

try

 

{return DBManager.GetObjects("DocumentTreeItem", true).GetContent();
}

 

 

 

 

 

 

catch (Exception exc)

 

{

 

 

 

string msg = exc.Message;

 

 

 

 

throw;

 

}
 Were GetObjects returns an ObjectContainer.

But how do you detail with the changeset at the receiver? I am using MPF for the project that I am testing to see if OpenAccess will suit for this application.
I would like to load this tree and bind it to a RadTree for example.

Thanks in advanced

Hi Nigel,
the ChangeSet is used to pass information in the services because its serializable. You can use it in your receiver by creating a container and using the apply property on it to apply the returned ChangeSet from the service.
