DataView binding bug: still alive?

Question

There's a post by Ron Barone at http://social.msdn.microsoft.com/Forums/en-US/wpf/thread/e9ddd299-4182-4760-9ec8-68f49e8a59ba

He says: "The only way to rebuild the related view is to build the dataview over again and reset the data context.  I've tried every refresh trick I know of..."

I'm not able to digg into the bug at this moment, as I'm busy enough. Please say me that I'm wrong and master-detail binding works fine;)

Thanks!

Answer 2

Linda Liu, did you mention who feedbacked the issue?;)

Ron Barone says,
<CollectionViewSource x:Key="cvsParentT" />
  <CollectionViewSource x:Key="cvsChildT" Source="{Binding Source={StaticResource cvsParentT}, Path=FK_ParentT_ChildT}" />
stops working if parent key updated.

I'm still not sure the case posted by Ron Barone is the same as I feedbacked.
Unfortunately, I'm deeply burried in non-wpf app for now and have not enough time to validate the trouble. Ill try to repro it at home and post results here.

Answer 3

Linda Liu, unfortunately this is a bug. Feedbacked at https://connect.microsoft.com/VisualStudio/feedback/details/538103/wpf-dataset-master-detail-binding-issue.

Sample at http://sites.google.com/site/whocodes/home/WpfBinding.zip (Instructions are listed on the sample's screen).

Answer 4

Dear Linda, please, reopen the bug I've feedbacked at https://connect.microsoft.com/VisualStudio/feedback/details/538103/wpf-dataset-master-detail-binding-issue.

WPF binding (or RelatedDataView class itself) does not nandle case when master's key changed. Detail's keys ARE changed (FK's update rule set to cascade), but they are not displayed.

I really dislike the quiality of conect service. Every time I feedbacked, I need to run 2-3 loops of cross-comments on multiple threads on forums before getting any reaction (not positive, as a rule). It's take eight month just to connect with DataSet team member and finally report the previus bug directly to him. This time will be the same?

Answer 5

Hi Sinix,

Microsoft has replied your feedback, and it seems an ADO bug, I think ADO team will process it as soon as possible.
Thank you very much for your effects to improving the quality of the product from Microsoft.

Best regards,
Linda Liu
