Integration with DevExpress Grid in server mode

[crazypit]

Hello,

I'm trying to use the DevExpress Grid Linq Server Mode functionality along with the Devart DotConnect for Oracle provider. In short, DevEpxress provides a way to load data in a grid incrementally in server mode, using Linq to SQL classes.

I opened a ticket in DevExpress support and you can read all about it at : http://www.devexpress.com/Support/Center/p/Q202392.aspx

They came to the conclusion that there is a problem with the Devart provider.

I would be grateful if you examine the case and provide me with relevant feedback.

Thank you.

I have made some simple tests using your test project with the recent 5.20.27 Beta version of dotConnect for Oracle and everything succeeded.

Hello,

I tested the project again and i got the same results. It is very important for me to use this functionality.

I attach the call stack generated when i break in the frozen application.

It is apparent that an exception is raised with the following information :

Please provide some help for a registered user...

We are investigating the problem. I will let you know about the results as soon as possible.

Hello,

In addition, i think i found a bug.

If i generate the classes using the O-R tool, each business class e.g. Customer gets a Table attribute in which the name if the table is prefixed by the relevant default schema E.g. SCHEMA1.CUSTOMERS. If i use a different schema when i instantiate the DataContext class, data for Customers are still retrieved from the SCHEMA1.CUSTOMERS table!!! Both users have DBA priviledges and i think this is the reason behind the visibility of the old schema. If i change the attribute to point to a non existent schema, i get an error "table or view does not exist". It seems to me, that the tool should not prefix the table name with a user. If i just delete the schema prefix, everything works as expected.

Using the latest build 5.20.29, everything worked ok! The integration with the grid seems to be ok. I;ll get back to you if needed.

Thanks.
