Have you checked the OM to see if the the columns that have been set as keys do not have repetitive values in the database?

I just noticed that even with a table that has only 2 records it still gives that error.  The table with the 2 records has good data.  So if the data appears to be ok then what else can it be?]]> Tue, 10 Jul 2007 14:46:55 -700 http://www.ideablade.com/forum/forum_posts.asp?TID=121&PID=266#266 Unable to bind a grid. : Wyatt, I think that you are... http://www.ideablade.com/forum/forum_posts.asp?TID=121&PID=265#265 Author: davidklitzke

Wyatt,
 
I think that you are completely correct.  Bad data can certainly cause the problem that you are seeing, and I don't see anything wrong or suspicious in your code.

I am using the following code:

PersistenceManager manager = PersistenceManager.DefaultManager;

EntityQuery query = new EntityQuery(typeof(Customers), Customers.ActiveEntityColumn, EntityQueryOp.EQ, "True");

EntityList<Customers> customers = manager.GetEntities<Customers>(query);

dataGridViewMain.DataSource = customers;

When it gets to the EntityList<Customers> line of code it throws the following error: "An item with the same key has already been added.".

I have used DevForce before with no problems.  I think the main difference is the database that I am using.  I have no idea about the quality of the data in this database.  Could it be something to do with the data, or am I just using it incorrectly?

Please help..

Thanks,
Wyatt
