An item with the same key has already been added.

Has anybody faced this issue in WebHierarchicalDataGrid, I have used this control expanding till 3 levals without any problem.

But im having issues using a SelfRererencing table, any ideas... is that a BUG in the control?

Ex:

Id (PK)

name (Varchar)

ParentId (FK)

Hello

Please look at this post in our forum - http://forums.infragistics.com/forums/t/58654.aspx. the forum post contains a sample with self referenced table which you can run and examine on your own. The exceptions is caused by trying to add a table 2 times at the same level of the hierarchy

Hi madhu_penta,

Do you have a better stack trace of the exception? Or a sample website that reproduces this problem? If you do not have the latest Service Release for whatever version you're using, I would upgrade as well.

regards,
David Young
