Hi,

I have Q3 2010 asp.net ajax,  i found a bug when i implement with Programmatic data (BindtoDataset)
i have all value don't have parent value match. (in french :

Cette contrainte ne peut pas être activée, car toutes les valeurs n'ont pas de valeurs parentes correspondantes.

)
My table is like as :
id    parent_id  title
1     0               test1
2     0               test2
3     1               test3
4     2               test4
5     1               test5
6     2               test6

I don't understand cause if i implement with Ienumerable from my dataset it's works.

Have you an idea ?

thank's

Hello olivier,

In the dataSource the records representing root nodes should have null for parentId.
This should solve it!

Hello olivier,

Indeed, when Binding to Hierarchical Data the parent id must be null. However, when
Binding to ASP.NET DataSource Components (ObjectDataSource), the parent id can be 0.
