I'm trying to figure out how to wire up parent child relationships on a form using the ria stuff. On your bug system PDC demo, you use a collection insted of a child table. Can you point me toward some info on hoe to do this. More detailed examples on how to get the Binding UI to work would probably do it. Thanks Rob Hi David –

But I have some problems 1- My database is Oracle how can I connect with it. 2- I have 150 tables at my hr can you give me a method for dynamic binding Ex: one or two classes for many forms (it is better for maintenance). 3- I need a method for modal dialog that return one or more value to the parent form. 4- What about reports? That is my problems to transfer my business application. Thanx again Hi David, Thanx for your example. But I have some problems

1- My database is Oracle how can I connect with it.

2- I have 150 tables at my hr can you give me a method for dynamic binding Ex: one or two classes for many forms (it is better for maintenance).

3- I need a method for modal dialog that return one or more value to the parent form.

4- What about reports?

That is my problems to transfer my business application.

Thanx again

I've read the referenced MS page and added code to every config file in the solution but still get the error.

And I'm not even talking about John Papa's presentation, he had not enough time to discuss about Prism and SL4. However none of you covered such topic as deleting items using RIA. I know there was a bug in previous version when you delete from local collection but the item wasn't deleted from bound DataGrid. Can you update your sample with such a functionality, when an empowered user can delete an Issue and all its related information. Also I noticed when you were updating an issue as solved the grid didn't refresh automatically, can you check on this as well? Thx and keep doing a great job.
