!!> Hello Ken,
!>
!> Thanks very much for your feedback.
!>
!> The problem is: When a typed dataset with annotations is return via a Web
!Service, annotations are lost in client side typed
!> dataset generated proxy. Please correct me if I have misunderstood the
!issue.
!>
!> This is a known "by design" behavior in the RTM release of the .NET
!Framework. Related reports have been filed and are
!> being investigated to implement it in a future release of .NET framework.
!>
!> Now the workaround resolution is to add code manually to the generated
!Typed DataSet Class to define and set extended
!> properties that match the codegen annotations.
!>
!> For an example, To one of the generated typed dataset classes[which has
!annotations] I added the following:
!>
!> this.columnAddress.ExtendedProperties.Add("nullValue", "_throw");
!> this.columnCity.ExtendedProperties.Add("nullValue", "_null");
!> this.columnPostalCode.ExtendedProperties.Add("nullValue", "toy");
!> this.columnCountry.ExtendedProperties.Add("nullValue", "");
!> this.columnPhone.ExtendedProperties.Add("nullValue", "_empty");
!> this.columnShipVia.ExtendedProperties.Add("nullValue", "0");
!> this.columnOrderDate.ExtendedProperties.Add("nullValue", "2000-01-01");
!>
!> The proxy generated on the client side would be with the necessary code
!required for these extended property
!> annotations..for ex, the client side proxy code is like:
!>
!> public string Phone {
!> get {
!> if (this.IsPhoneNull()) {
!> return string.Empty;
!> }
!> else {
!> return ((string)(this[this.tableCustomers.PhoneColumn]));
!> }
!> }
!> set {
!> this[this.tableCustomers.PhoneColumn] = value;
!> }
!> }
!>
!> Hope it helps.
