Hi,
A seconde question about the DataSource is how can we get the Data of a subset into f.i. a grid. Here's the code we use for our JSON services.
The consumed class VMRoot looks like this:
[DataContract]
public partial class VMRoot : Viewmodel
{
public VMRoot() {}
public static VMRoot GetById(object sender, int id)
{
return CallGetVMById<VMRoot>("", id);
}
public static VMEntitySet<VMRoot> AllVMRootList(object sender)
{
return (VMEntitySet<VMRoot>)CallGetVMAllList<VMEntitySet<VMRoot>>(sender);
}
[DataMember]
public Int32 Id
{
get { return CallGetData<Int32>("Id"); }
set { CallSetData ("Id", value); }
}
[DataMember]
public DateTime CreatedOn
{
get { return CallGetData<DateTime>("CreatedOn"); }
set { CallSetData ("CreatedOn", value); }
}
[DataMember]
public Int32 CreatedBy
{
get { return CallGetData<Int32>("CreatedBy"); }
set { CallSetData ("CreatedBy", value); }
}
[DataMember]
public DateTime ChangedOn
{
get { return CallGetData<DateTime>("ChangedOn"); }
set { CallSetData ("ChangedOn", value); }
}
[DataMember]
public Int32 ChangedBy
{
get { return CallGetData<Int32>("ChangedBy"); }
set { CallSetData ("ChangedBy", value); }
}
}
The VMEntitySet is an ObservableCollection which contains VMProjectRegel objects. These are defined like so:
The JSON we receive looks like this:
The DataSource is defined like so:
after executing the
dataSourceprojecten.read() the data is available for the main list but how do we specify the fetch for the ProjectRegelsList in f.i. a grid?
This is what I have tried (among many other attempts) to get it to work:
