Hello Bertrand,

In my attempt to reproduce the described issue I created a test project. I could not replicate the issue on  my end. I attached the sample to this forum thread. Please examine it and tell me if I am missing something.

If the problem persists, I suggest you modify the attached web site in order to replicate the issue and send it back via a regular support thread. Thus I will do my best to assist you further with the resolution.

Kind regards,

Thk you,

Effectively in your example, it works for certain things.

I do not understand why I have problems with the example of the site .. However, in your file, the first level, we track all the elements, it seems to me that there is a problem in relation to the example on your site ...

Let me explain, I use the version 2008.3.1314.20 and in your example, tree works, but in principal level, I see all the records and sub record are also under correct parent record (but also in first level).

Note : update don't work but i suppose it is a little error ... i don't checked

Hi Bertrand,

We are not familiar with such a problem related with our live demo. It is working as expected according the applied settings.

Fill free to use my sample project as a reference for the discussion. The hierarchy is shown only to the first level, because MaximumDepth property is set to "0". Thus the grid has only one row hierarchy. You can easily set it to "5" for instance.

In my sample project only the insertion of rows is implemented. The update, delete and etc. are not implemented, as they are not related to the subject.

AND after :

5    c.a
6    c.b

Thk you

Hello Bertrand,

Unfortunately I am not able to determine where the exact source of the issue is. You can try to set HierarchyLoadMode to "ServerOnDemand" and to verify that the problem still persists.
If it is convenient for you, I will ask you to post mark-up code of the RadGrid declaration in order to review grid's settings.
