return object from WebMethod

[kids_pro]

Hi there,

I try to create a webmethod in webservice by return DataView but each time I
compile there is and error
[WebMethod]
public DataView GetAuthor(){
.....
return ds.Tables["Authors"].DefaultView;
}

You must implement the Add(System.Data.DataRowView) method on
System.Data.DataView because it inherits from ICollection.

Please kindly advice.

Regards

Essentially whats happening is that VS.net creates a proxy class called
Reference.cs. Out there it defines the DataView property which is
obviously not implemented correctly as its only a placeholder value
object. Try changing the DataView return type to object and you should
be good to go
Thanks
